Other + toolchains will likely cause problems. + +GNU Toolchain Options +===================== + + The NuttX make system will support the several different toolchain options. + + All testing has been conducted using the CodeSourcery GCC toolchain. To use + a different toolchain, you simply need to add change to one of the following + configuration options to your .config (or defconfig) file: + + CONFIG_ARMV7A_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery under Windows + CONFIG_ARMV7A_TOOLCHAIN_CODESOURCERYL=y : CodeSourcery under Linux + CONFIG_ARMV7A_TOOLCHAIN_ATOLLIC=y : Atollic toolchain for Windos + CONFIG_ARMV7A_TOOLCHAIN_DEVKITARM=y : devkitARM under Windows + CONFIG_ARMV7A_TOOLCHAIN_BUILDROOT=y : NuttX buildroot under Linux or Cygwin (default) + CONFIG_ARMV7A_TOOLCHAIN_GNU_EABIL=y : Generic GCC ARM EABI toolchain for Linux + CONFIG_ARMV7A_TOOLCHAIN_GNU_EABIW=y : Generic GCC ARM EABI toolchain for Windows + + The CodeSourcery GCC toolchain is selected with + CONFIG_ARMV7A_TOOLCHAIN_CODESOURCERYW=y and setting the PATH variable + appropriately. + + NOTE about Windows native toolchains + ------------------------------------ + + There are several limitations to using a Windows based toolchain in a + Cygwin environment. The three biggest are: + + 1. The Windows toolchain cannot follow Cygwin paths. Path conversions are + performed automatically in the Cygwin makefiles using the 'cygpath' + utility but you might easily find some new path problems. If so, check + out 'cygpath -w' + + 2. Windows toolchains cannot follow Cygwin symbolic links. Many symbolic + links are used in Nuttx (e.g., include/arch). The make system works + around these problems for the Windows tools by copying directories + instead of linking them. But this can also cause some confusion for + you: For example, you may edit a file in a "linked" directory and find + that your changes had no effect. That is because you are building the + copy of the file in the "fake" symbolic directory. If you use a\ + Windows toolchain, you should get in the habit of making like this: + + make clean_context all + + An alias in your .bashrc file might make that less painful. + + 3. Dependencies are not made when using Windows versions of the GCC. This is + because the dependencies are generated using Windows paths which do not + work with the Cygwin make. + + MKDEP = $(TOPDIR)/tools/mknulldeps.sh + +IDEs +==== + + NuttX is built using command-line make. It can be used with an IDE, but some + effort will be required to create the project. + + Makefile Build + -------------- + Under Eclipse, it is pretty easy to set up an "empty makefile project" and + simply use the NuttX makefile to build the system. That is almost for free + under Linux. Under Windows, you will need to set up the "Cygwin GCC" empty + makefile project in order to work with Windows (Google for "Eclipse Cygwin" - + there is a lot of help on the internet). + + Native Build + ------------ + Here are a few tips before you start that effort: + + 1) Select the toolchain that you will be using in your .config file + 2) Start the NuttX build at least one time from the Cygwin command line + before trying to create your project. This is necessary to create + certain auto-generated files and directories that will be needed. + 3) Set up include pathes: You will need include/, arch/arm/src/sam34, + arch/arm/src/common, arch/arm/src/armv7-m, and sched/. + 4) All assembly files need to have the definition option -D __ASSEMBLY__ + on the command line. + + Startup files will probably cause you some headaches. The NuttX startup file + is arch/arm/src/sam34/sam_vectors.S. You may need to build NuttX + one time from the Cygwin command line in order to obtain the pre-built + startup object needed by an IDE. + +NuttX EABI "buildroot" Toolchain +================================ + + A GNU GCC-based toolchain is assumed. The files */setenv.sh should + be modified to point to the correct path to the Cortex-M3 GCC toolchain (if + different from the default in your PATH variable). + + If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX + SourceForge download site (https://sourceforge.net/projects/nuttx/files/buildroot/). + This GNU toolchain builds and executes in the Linux or Cygwin environment. + + 1. You must have already configured Nuttx in <some-dir>/nuttx. + + cd tools + ./configure.sh sama5d3-xplained/<sub-dir> + + 2. Download the latest buildroot package into <some-dir> + + 3. unpack the buildroot tarball. The resulting directory may + have versioning information on it like buildroot-x.y.z. If so, + rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot. + + 4. cd <some-dir>/buildroot + + 5. Copy the configuration file from the configs/ sub-directory to the + top-level build directory: + + cp configs/cortexa8-eabi-defconfig-4.8.2 .config + + 6a. You may wish to modify the configuration before you build it. For + example, it is recommended that you build the kconfig-frontends tools, + generomfs, and the NXFLAT tools as well. You may also want to change + the selected toolchain. These reconfigurations can all be done with + + make menuconfig + + 6b. If you chose to make the configuration with no changes, then you + should still do the following to make certain that the build + configuration is up-to-date: + + make oldconfig + + 7. make + + 8. Edit setenv.h, if necessary, so that the PATH variable includes + the path to the newly built binaries. + + See the file configs/README.txt in the buildroot source tree. That has more + details PLUS some special instructions that you will need to follow if you are + building a Cortex-M3 toolchain for Cygwin under Windows. + +NXFLAT Toolchain +================ + + If you are *not* using the NuttX buildroot toolchain and you want to use + the NXFLAT tools, then you will still have to build a portion of the buildroot + tools -- just the NXFLAT tools. The buildroot with the NXFLAT tools can + be downloaded from the NuttX SourceForge download site + (https://sourceforge.net/projects/nuttx/files/). + + This GNU toolchain builds and executes in the Linux or Cygwin environment. + + 1. You must have already configured Nuttx in <some-dir>/nuttx. + + cd tools + ./configure.sh sama5d3-xplained/<sub-dir> + + 2. Download the latest buildroot package into <some-dir> + + 3. unpack the buildroot tarball. The resulting directory may + have versioning information on it like buildroot-x.y.z. If so, + rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot. + + 4. cd <some-dir>/buildroot + + 5. cp configs/cortexm3-defconfig-nxflat .config + + 6. make oldconfig + + 7. make + + 8. Edit setenv.h, if necessary, so that the PATH variable includes + the path to the newly built NXFLAT binaries. + + NOTE: There are some known incompatibilities with 4.6.3 EABI toolchain + and the NXFLAT tools. See the top-level TODO file (under "Binary + loaders") for more information about this problem. If you plan to use + NXFLAT, please do not use the GCC 4.6.3 EABI toochain. + +Loading Code into SRAM with J-Link +================================== + + Loading code with the Segger tools and GDB + ------------------------------------------ + + 1) Change directories into the directory where you built NuttX. + 2) Start the GDB server and wait until it is ready to accept GDB + connections. + 3) Then run GDB like this: + + $ arm-none-eabi-gdb + (gdb) target remote localhost:2331 + (gdb) mon reset + (gdb) load nuttx + (gdb) ... start debugging ... + + Loading code using J-Link Commander + ---------------------------------- + + J-Link> r + J-Link> loadbin <file> <address> + J-Link> setpc <address of __start> + J-Link> ... start debugging ... + +Writing to FLASH using SAM-BA +============================= + + Assumed starting configuration: + + 1. You have installed the J-Link CDC USB driver (Windows only, there is + no need to install a driver on any regular Linux distribution), + 2. You have the USB connected to DBGU port (J23) + 3. Terminal configuration: 115200 8N1 + + Using SAM-BA to write to FLASH: + + 1. Exit the terminal emulation program and remove the USB cable from + the DBGU port (J23) + 2. Connect the USB cable to the device USB port (J6) + 3. JP9 must open (BMS == 1) to boot from on-chip Boot ROM. + 4. Press and maintain PB4 CS_BOOT button and power up the board. PB4 + CS_BOOT button prevents booting from Nand or serial Flash by + disabling Flash Chip Selects after having powered the board, you can + release the PB4 BS_BOOT button. + 5. On Windows you may need to wait for a device driver to be installed. + 6. Start the SAM-BA application, selecting (1) the correct USB serial + port, and (2) board = at91sama5d3-xplained. + 7. The SAM-BA menu should appear. + 8. Select the FLASH bank that you want to use and the address to write + to and "Execute" + 9. When you are finished writing to FLASH, remove the USB cable from J6 + and re-connect the serial link on USB CDC / DBGU connector (J23) and + re-open the terminal emulator program. + 10. Power cycle the board. + +Creating and Using NORBOOT +========================== + + In order to have more control of debugging code that runs out of NOR FLASH, + I created the sama5d3-xplained/norboot configuration. That configuration is + described below under "Configurations." + + Here are some general instructions on how to build an use norboot: + + Building: + 1. Remove any old configurations (if applicable). + + cd <nuttx> + make distclean + + 2. Install and build the norboot configuration. This steps will establish + the norboot configuration and setup the PATH variable in order to do + the build: + + cd tools + ./configure.sh sama5d3-xplained/<subdir> + cd - + . ./setenv.sh + + Before sourcing the setenv.sh file above, you should examine it and + perform edits as necessary so that TOOLCHAIN_BIN is the correct path + to the directory than holds your toolchain binaries. + + NOTE: Be aware that the default norboot also disables the watchdog. + Since you will not be able to re-enable the watchdog later, you may + need to set CONFIG_SAMA5_WDT=y in the NuttX configuration file. + + Then make norboot: + + make + + This will result in an ELF binary called 'nuttx' and also HEX and + binary versions called 'nuttx.hex' and 'nuttx.bin'. + + 3. Rename the binaries. Since you will need two versions of NuttX: this + norboot version that runs in internal SRAM and another under test in + NOR FLASH, I rename the resulting binary files so that they can be + distinguished: + + mv nuttx norboot + mv nuttx.hex norboot.hex + mv nuttx.bin norboot.bin + + 4. Build your NOR configuration and write this into NOR FLASH. Here, for + example, is how you would create the NSH NOR configuration: + + cd <nuttx> + make distclean # Remove the norboot configuration + cd tools + ./configure.sh sama5d3-xplained/nsh # Establish the NSH configuration + cd - + make # Build the NSH configuration + + Then use SAM-BA to write the nuttx.bin binary into NOR FLASH. This + will involve holding the CS_BOOT button and power cycling to start + the ROM loader. The SAM-BA serial connection will be on the device + USB port, not the debug USB port. Follow the SAM-BA instruction to + write the nuttx.bin binary to NOR FLASH. + + 5. Restart the system without holding CS_BOOT to get back to the normal + debug setup. + + 6. Then start the J-Link GDB server and GDB. In GDB, I do the following: + + (gdb) mon reset # Reset and halt the CPU + (gdb) load norboot # Load norboot into internal SRAM + (gdb) mon go # Start norboot + (gdb) mon halt # Break in + (gdb) mon reg pc = 0x10000040 # Set the PC to NOR flash entry point + (gdb) mon go # And jump into NOR flash + + The norboot program can also be configured to jump directly into + NOR FLASH without requiring the final halt and go by setting + CONFIG_SAMA5D3XPLAINED_NOR_START=y in the NuttX configuration. However, + since I have been debugging the early boot sequence, the above + sequence has been most convenient for me since it allows me to + step into the program in NOR. + + 7. An option is to use the SAM-BA tool to write the NORBOOT image into + Serial FLASH. Then, the system will boot from Serial FLASH by + copying the NORBOOT image in SRAM which will run and then start the + image in NOR FLASH automatically. This is a very convenient usage! + + NOTES: (1) There is jumper on the CM module that must be closed to + enable use of the AT25 Serial Flash. (2) If using SAM-BA, make sure + that you load the NOR boot program into the boot area via the pull- + down menu. + + STATUS: + 2014-7-30: I have been unable to execute these configurations from NOR + FLASH by closing the BMS jumper (J9). As far as I can tell, this + jumper does nothing on my board??? So I have been using the norboot + configuration exclusively to start the program-under-test in NOR FLASH. + +Buttons and LEDs +================ + + Buttons + ------- + + The following push buttons switches are available: + + 1. One board reset button (BP2). When pressed and released, this push + button causes a power-on reset of the whole board. + + 2. One wakeup pushbutton that brings the processor out of Low-power mode + (BP1) + + 3. One user pushbutton (BP3) + + Only the user push button (BP3) is controllable by software: + + - PE29. Pressing the switch connect PE29 to ground. Therefore, PE29 + must be pulled high internally. When the button is pressed the SAMA5 + will sense "0" is on PE29. + + LEDs + ---- + There are two LEDs on the SAMA5D3 series-CM board that can be controlled + by software. A blue LED is controlled via PIO pins. A red LED normally + provides an indication that power is supplied to the board but can also + be controlled via software. + + PE23. This blue LED is pulled high and is illuminated by pulling PE23 + low. + + PE24. The red LED is also pulled high but is driven by a transistor so + that it is illuminated when power is applied even if PE24 is not + configured as an output. + + These LEDs are not used by the board port unless CONFIG_ARCH_LEDS is + defined. In that case, the usage by the board port is defined in + include/board.h and src/sam_leds.c. The LEDs are used to encode OS-related + events as follows: + + SYMBOL Meaning LED state + Blue Red + ------------------- ----------------------- -------- -------- + LED_STARTED NuttX has been started OFF OFF + LED_HEAPALLOCATE Heap has been allocated OFF OFF + LED_IRQSENABLED Interrupts enabled OFF OFF + LED_STACKCREATED Idle stack created ON OFF + LED_INIRQ In an interrupt No change + LED_SIGNAL In a signal handler No change + LED_ASSERTION An assertion failed No change + LED_PANIC The system has crashed OFF Blinking + LED_IDLE MCU is is sleep mode Not used + + Thus if the blue LED is statically on, NuttX has successfully booted and + is, apparently, running normally.

Properties: It does support some wear- + leveling like NXFFS, but like FAT, cannot handle bad blocks and like + NXFFS, it will try to re-write erased bits. + + Using NAND with NXFFS + --------------------- + + With the options CONFIG_SAMA5D3XPLAINED_NAND_AUTOMOUNT=y and + CONFIG_SAMA5D3XPLAINED_NAND_NXFFS=y, the NAND FLASH will be mounted in the NSH + start-up logic before the NSH prompt appears. There is no feedback as + to whether or not the mount was successful. You can, however, see the + mounted file systems using the nsh 'mount' command: + + nsh> mount + /mnt/nand type nxffs + + Then NAND can be used like any other file system: + + nsh> echo "This is a test" >/mnt/nand/atest.txt + nsh> ls -l /mnt/nand + /mnt/nand: + ---x--x--x 16 atest.txt + nsh> cat /mnt/nand/atest.txt + This is a test + + The NAND volume can be un-mounted with this comment: + + nsh> umount /mnt/nand + nsh> mount + + And re-mounted with this command: + + nsh> mount -t nxffs /mnt/mystuff + nsh> mount + /mnt/mystuff type nxffs + + NOTES: + 1. NXFFS can be very slow. The first time that you start the system, + be prepared for a wait; NXFFS will need to format the NAND volume. + I have lots of debug on so I don't yet know what the optimized wait + will be. But with debug ON, software ECC, and no DMA the wait is + in many tens of minutes (and substantially longer if many debug + options are enabled. + + [I don't yet have data for the more optimal cases. It will be + significantly less, but still not fast.] + + 2. On subsequent boots, after the NXFFS file system has been created + the delay will be less. When the new file system is empty, it will + be very fast. But the NAND-related boot time can become substantial + when there has been a lot of usage of the NAND. This is because + NXFFS needs to scan the NAND device and build the in-memory dataset + needed to access NAND and there is more that must be scanned after + the device has been used. You may want to create a separate thread at + boot time to bring up NXFFS so that you don't delay the boot-to-prompt + time excessively in these longer delay cases. + + 3. There is another NXFFS related performance issue: When the FLASH + is fully used, NXFFS will restructure the entire FLASH, the delay + to restructure the entire FLASH will probably be even larger. This + solution in this case is to implement an NXFSS clean-up daemon that + does the job a little-at-a-time so that there is no massive clean-up + when the FLASH becomes full. + + 4. Bad NXFFS behavior with NAND: If you restart NuttX, the files that + you wrote to NAND will be gone. Why? Because the multiple writes + have corrupted the NAND ECC bits. See STATUS below. NXFFS would + require a major overhaul to be usable with NAND. + + Using NAND with FAT + ------------------- + + If configured for FAT, the system will create block driver at + /dev/mtdblock0: + + NuttShell (NSH) + nsh> ls /dev + /dev: + console + mtdblock0 + null + ttyS0 + + You will not that the system comes up immediately because there is not + need to scan the volume in this case.. + + The NSH 'mkfatfs' command can be used to format a FAT file system on + NAND. + + nsh> mkfatfs /dev/mtdblock0 + + This step, on the other hand, requires quite a bit of time. + + And the FAT file system can be mounted like: + + nsh> mount -t vfat /dev/mtdblock0 /mnt/nand + nsh> ls /mnt/nand + /mnt/nand: + + nsh> echo "This is a test" > /mnt/nand/atest.txt + + NOTE: This will take a long time because it will require reading, + modifying, and re-writing the 128KB erase page! + + nsh> ls -l /mnt/nand + /mnt/nand: + -rw-rw-rw- 16 atest.txt + + nsh> cat /mnt/fat/atest.txt + This is a test + + NOTES: + + 1. Unlike NXFFS, FAT can work with NAND (at least with PMECC disabled). + But there are some significant issues. + + 2. First, each NAND write access will cause a 256KB data transfer: It + will read the entire 128KB erase block, modify it and write it back + to memory. There is some caching logic so that this cached erase + block can be re-used if possible and writes will be deferred as long + as possible. + + 3. If you hit a bad block, then FAT is finished. There is no mechanism + in place in FAT not to mark and skip over bad blocks. + + What is Needed + -------------- + + What is needed to work with FAT properly would be another MTD layer + between the FTL layer and the NAND FLASH layer. That layer would + perform bad block detection and sparing so that FAT works transparently + on top of the NAND. + + Another, less general, option would be support bad blocks within FAT. + + STATUS SUMMARY + -------------- + + 1. PMECC appears to be working in that I can write a NAND block with its + ECC and read the block back and verify that that is are no bit + failures. However, when attempting to work with FAT, it does not + work correctly: The MBR is written and read back correctly, but gets + corrupted later for unknown reasons. + + 2. DMA works (at least with software ECC), but I have seen occasional + failures. I recommend enabling DMA with caution. + + In NuttX, DMA will also cost two context switches (and, hence, four + register state transfers). With smaller NAND page sizes (say 2KiB and + below), I would expect little or no performance improvement with DMA + for this reason. + + 3. NXFFS does not work with NAND. NAND differs from other other FLASH + types several ways. For one thing, NAND requires error correction + (ECC) bytes that must be set in order to work around bit failures. + This affects NXFFS in two ways: + + a. First, write failures are not fatal. Rather, they should be tried by + bad blocks and simply ignored. This is because unrecoverable bit + failures will cause read failures when reading from NAND. Setting + the CONFIG_EXPERIMENTAL+CONFIG_NXFFS_NANDs option will enable this + behavior. + + b. Secondly, NXFFS will write a block many times. It tries to keep + bits in the erased state and assumes that it can overwrite those bits + to change them from the erased to the non-erased state. This works + will with NOR-like FLASH. NAND behaves this way too. But the + problem with NAND is that the ECC bits cannot be re-written in this + way. So once a block has been written, it cannot be modified. This + behavior has NOT been fixed in NXFFS. Currently, NXFFS will attempt + to re-write the ECC bits causing the ECC to become corrupted because + the ECC bits cannot be overwritten without erasing the entire block. + + This may prohibit NXFFS from ever being used with NAND. + + 4.

At the conclusion of + the make, the nuttx binary will reside in an ELF file called, simply, nuttx. + + make + + The <subdir> that is provided above as an argument to the tools/configure.sh + must be is one of the following. + + NOTES: + + 1. These configurations use the mconf-based configuration tool. To + change any of these configurations using that tool, you should: + + a. Build and install the kconfig-mconf tool. See nuttx/README.txt + and misc/tools/ + + b. Execute 'make menuconfig' in nuttx/ in order to start the + reconfiguration process. + + 2. Unless stated otherwise, all configurations generate console + output on UART0 (J3). + + 3. All of these configurations use the Code Sourcery for Windows toolchain + (unless stated otherwise in the description of the configuration). That + toolchain selection can easily be reconfigured using 'make menuconfig'. + Here are the relevant current settings: + + Build Setup: + CONFIG_HOST_WINDOWS=y : Microsoft Windows + CONFIG_WINDOWS_CYGWIN=y : Using Cygwin or other POSIX environment + + System Type -> Toolchain: + CONFIG_ARMV7A_TOOLCHAIN_GNU_EABIW=y : GNU EABI toolchain for windows + + That same configuration will work with Atmel GCC toolchain. The only + change required to use the Atmel GCC toolchain is to change the PATH + variable so that those tools are selected instead of the CodeSourcery + tools. Try 'which arm-none-eabi-gcc' to make sure that you are + selecting the right tool. + + The setenv.sh file is available for you to use to set the PATH + variable. The path in the that file may not, however, be correct + for your installation. + + See also the "NOTE about Windows native toolchains" in the section call + "GNU Toolchain Options" above. + + !!!WARNING!!! The first time that you type 'make', the system will + configure itself based on the settings in the .config file. One of + these settings can cause a lot of confusion if you configure the build + in the wrong state: If you are running on Linux, make *certain* that + you have CONFIG_HOST_LINUX=y *before* the first make or you will + create a very corrupt configuration that may not be easy to recover + from. + + Configuration Sub-directories + ----------------------------- + Summary: Some of the descriptions below are long and wordy. Here is the + concise summary of the available SAMA5D3-Xplained configurations: + + norboot: + This is a little program to help debug of code in NOR flash. I wrote + it because I don't yet understand how to get the SAMA5 to boot from + NOR FLASH. See the description below and the section above entitled + "Creating and Using NORBOOT" for more information + nsh: This is another NSH configuration, not too different from the + demo configuration. The nsh configuration is, however, bare bones. + It is the simplest possible NSH configuration and is useful as a + platform for debugging and integrating new features in isolation. + + There may be issues with some of these configurations. See the details + before of the status of individual configurations. + + Now for the gory details: + + norboot: + This is a little program to help debug of code in NOR flash. It + does the following: + + - It enables and configures NOR FLASH, then + - Waits for you to break in with GDB. + + At that point, you can set the PC and begin executing from NOR FLASH + under debug control. See the section entitled "Creating and Using + NORBOOT" above. + + NOTES: + + 1. This program derives from the hello configuration. All of the + notes there apply to this configuration as well. + + 2. The default norboot program initializes the NOR memory, + displays a message and halts. The norboot program can also be + configured to jump directly into NOR FLASH without requiring the + final halt and go by setting CONFIG_SAMA5D3XPLAINED_NOR_START=y in the + NuttX configuration. + + 3. Be aware that the default norboot also disables the watchdog. + Since you will not be able to re-enable the watchdog later, you may + need to set CONFIG_SAMA5_WDT=y in the NuttX configuration file. + + 4. If you put norboot on the Serial FLASH, you can automatically + boot to NOR on reset. See the section "Creating and Using NORBOOT" + above. + + STATUS: + See the To-Do list below + + nsh: + + This configuration directory provide the NuttShell (NSH). There are + two NSH configurations: nsh and demo. The difference is that nsh is + intended to be a very simple NSH configuration upon which you can build + further functionality. The demo configuration, on the other hand, is + intended to be a rich configuration that shows many features all working + together. + + NOTES: + 1. This configuration uses the default USART1 serial console. That + is easily changed by reconfiguring to (1) enable a different + serial peripheral, and (2) selecting that serial peripheral as + the console device. + + 2. By default, this configuration is set up to build on Windows + under either a Cygwin or MSYS environment using a recent, Windows- + native, generic ARM EABI GCC toolchain (such as the CodeSourcery + toolchain). Both the build environment and the toolchain + selection can easily be changed by reconfiguring: + + CONFIG_HOST_WINDOWS=y : Windows operating system + CONFIG_WINDOWS_CYGWIN=y : POSIX environment under windows + CONFIG_ARMV7A_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery for Windows + + If you are running on Linux, make *certain* that you have + CONFIG_HOST_LINUX=y *before* the first make or you will create a + corrupt configuration that may not be easy to recover from. See + the warning in the section "Information Common to All Configurations" + for further information. + + 3. This configuration executes out of CS0 NOR flash and can only + be loaded via SAM-BA. The are the relevant configuration options + are provided above in the section entitled "NOR FLASH Support". + + 4. This configuration has support for NSH built-in applications enabled. + However, no built-in applications are selected in the base configuration. + + 5. Data resides in ISRAM, but can be moved to SDRAM as described above + under "SDRAM Data Configuration." + + 6. This configuration has support for the FAT file system built in. However, + by default, there are no block drivers initialized. The FAT file system can + still be used to create RAM disks. + + 7. SDRAM support can be enabled by modifying your NuttX configuration as + described above in the paragraph entitle "SDRAM Support" + + 8. The SAMA5D3 Xplained board includes an option serial DataFlash. Support + for that serial FLASH can be enabled by modifying the NuttX configuration + as described above in the paragraph entitled "AT25 Serial FLASH". + + 9. Enabling HSMCI support. The SAMA5D3-Xplained provides a two SD memory + card slots: (1) a full size SD card slot (J10), and (2) a microSD + memory card slot (J11). The full size SD card slot connects via HSMCI0; + the microSD connects vi HSMCI1. Support for both SD slots can be enabled + with the settings provided in the paragraph entitled "HSMCI Card Slots" + above. + + 10. Support the USB low-, high- and full-speed OHCI host driver can be enabled + by changing the NuttX configuration file as described in the section + entitled "USB High-Speed Host" above. + + 11. Support the USB high-speed USB device driver (UDPHS) can be enabled + by changing the NuttX configuration file as described above in the + section entitled "USB High-Speed Device." + + 12. I2C Tool. NuttX supports an I2C tool at apps/system/i2c that can be + used to peek and poke I2C devices. See the discussion above under + "I2C Tool" for detailed configuration settings. + + 13. Networking support via the can be added to NSH by modifying the + configuration. See the "Networking" section above for detailed + configuration settings. + + 16. The Real Time Clock/Calendar RTC) may be enabled by reconfiguring NuttX. + See the section entitled "RTC" above for detailed configuration settings. + + 17. This example can be configured to exercise the watchdog timer test + (apps/examples/watchdog). See the detailed configuration settings in + the section entitled "Watchdog Timer" above. + + 18. This example can be configured to enable the SAMA5 TRNG peripheral so + that it provides /dev/random. See the section entitled "TRNG and + /dev/random" above for detailed configuration information. + + 19. See also the sections above for additional configuration options: + "CAN Usage", "SAMA5 ADC Support", "SAMA5 PWM Support", "I2S Audio + Support" + + STATUS: + See the To-Do list below + + I2C + 2014-9-12: The I2C tool, however, seems to work well. It succesfully + enumerates the devices on the bus and successfully exchanges a few + commands. The real test of the come later when a real I2C device is + integrated. + +To-Do List +========== + +1) Currently the SAMA5Dx is running at 396MHz in these configurations. This + is because the timing for the PLLs, NOR FLASH, and SDRAM came from the + Atmel NoOS sample code which runs at that rate. The SAMA5Dx is capable + of running at 528MHz, however. The setup for that configuration exists + in the Bareboard assembly language setup and should be incorporated. + +2) Most of these configurations execute from NOR FLASH. I have been unable + to execute these configurations from NOR FLASH by closing the BMS jumper + (J9). As far as I can tell, this jumper does nothing on my board??? I + have been using the norboot configuration to start the program in NOR + FLASH (see just above). See "Creating and Using NORBOOT" above. + +3) Neither USB OHCI nor EHCI support Isochronous endpoints. Interrupt + endpoint support in the EHCI driver is untested (but works in similar + EHCI drivers). + +4) HSCMI TX DMA support is currently commented out. + +5) I believe that there is an issue when the internal AT25 FLASH is + formatted by NuttX. That format works fine with Linux, but does not + appear to work with Windows. Reformatting on Windows can resolve this. + NOTE: This is not a SAMA5Dx issue. + + UPDATE: Two important bugs were recently fixed in the NuttX FAT + formatting function (mkfatfs). It is likely that these fixes will + eliminate this issue, but that has not yet been verified. + +6) CAN testing has not yet been performed due to issues with cabling. I + just do not have a good test bed (or sufficient CAN knowledge) for + good CAN testing. + +7) The NxWM example does not work well. This example was designed to work + with much smaller displays and does not look good or work well with the + SAMA5D3-Xplained's 800x480 display. See above for details. + +8) I have a Camera, but there is still no ISI driver. I am not sure what to + do with the camera. NuttX needs something like V4L to provide the + definition for what a camera driver is supposed to do. + + I will probably develop a test harness for ISI, but it is of only + minimal value with no OS infrastructure to deal with images and video. + +9) GMAC has only been tested on a 10/100Base-T network. I don't have a + 1000Base-T network to support additional testing. diff --git a/nuttx/configs/sama5d3-xplained/include/board.h b/nuttx/configs/sama5d3-xplained/include/board.h new file mode 100644 index 000000000..59292dfdf --- /dev/null +++ b/nuttx/configs/sama5d3-xplained/include/board.h @@ -0,0 +1,341 @@ +/************************************************************************************ + * configs/sama5d3-xplained/include/board.h + * + * Copyright (C) 2014 Gregory Nutt.
