-OSTEST Project
---------------
-
-ostest.zfpproj is a simple ZDS II - ZNEO 5.0.1 project that will allow you
-  to use the ZDS-II debugger.  Before using, copy the following files from
-  the toplevel directory:
-
-    nuttx.hex, nuttx.map, nuttx.lod
-
-  to this directory as:
-
-    ostest.hex, ostest.map, ostest.lod
-
-Loading and Executing Code
---------------------------
-
-1. Copy the files to this directory as described above
-2. Connect the ZiLOG XTools USB debugger.
-3. Install the USB driver from the ZDS-II device_drivers directory
-4. Start ZDS-II and load the ostest.zfpproj project
-5. In the debug tab, connect to the debugger
-6. In the debug tab, load code, reset, and go
-
-Hmmm... it appears that the code does not run if started by a hardware reset.
-It runs only when started via the debugger.  What is up with that?
-
-Console Output
---------------
-
-OS test results will be provided on the serial console at 57600 8N1 baud.
-
-STATUS
-------
-
-1. This configuration does not run correctly.  There is currently a problem
-   with the SRAM accesses.

-    NOTES:
-
-    1. This configuration uses the mconf-based configuration tool.  To
-       change this configuration 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. By default, this configuration assumes that you are using the
-       Cygwin environment on Windows.  An option is to use the native
-       CMD.exe window build as described in the top-level README.txt
-       file.  To set up that configuration:
-
-       -CONFIG_WINDOWS_CYGWIN=y
-       +CONFIG_WINDOWS_NATIVE=y
-
-       And after configuring, make sure that CONFIG_APPS_DIR uses
-       the back slash character.  For example:
-
-        CONFIG_APPS_DIR="..\apps"
-
-      NOTES:
-      
-      a. If you need to change the toolchain path used in Make.defs, you
-         will need to use the short 8.3 filenames to avoid spaces.  On my
-         PC, C:\PROGRA~1\ is is C:\Program Files\ and C:\PROGRA~2\ is
-         C:\Program Files (x86)\
-      b. You can't use setenv.sh in the native Windows environment.  Try
-         scripts/setenv.bat instead.
-      c. At present, the native Windows build fails at the final link stages.
-         The failure is due to problems in arch/z80/src/nuttx.linkcmd that
-         is autogenerated by arch/z80/src/Makefile.zdsii.  The basic problem
-         is the spurious spaces and and carrirage returns are generated at
-         the end of the lines after a line continuation (\ ^M).  If these
-         trailing bad characters are manually eliminated, then the build
-         will succeed on the next try.

-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

-All features are enabled and all test pass *except* for the round-robin
-test.  However, it appears that some kept the interrupts disabled through-out
-the conduct of that test (I can tell because of the interrupt driven LED
-array on the board does not update when interrupts are disabled).  So I
-suspect that there is something else going on in that test case.

-    NOTES:
-
-    1. This configuration uses the mconf-based configuration tool.  To
-       change this configuration 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. Default toolchain:
-
-       CONFIG_HOST_WINDOWS=y                   : Builds under Windows
-       CONFIG_WINDOWS_CYGWIN=y                 : Using Cygwin
-       CONFIG_ARMV6M_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery for Windows

-       UART0 SIGNAL     J1 pin
-       ---------------- ---------
-       UART0_RX (PTA1)  J1, pin 2
-       UART0_TX (PTA2)  J1, pin 4
-
-       Ground is available on J2 pin 14.  3.3V is available on J3 and J4.
-
-       It is possible to configure NSH to use a USB serial console instead
-       of an RS-232 serial console.  However, that configuration has not
-       been impelmented as of this writing.

-    2. Default platform/toolchain:
-
-       CONFIG_HOST_LINUX=y                 : Linux (Cygwin under Windows okay too).

-    To switch to the Linux C32 toolchain you will have to change (1) the

-  ostest:
-  ------
-    This configuration directory, performs a simple OS test using
-    apps/examples/ostest.
-
-    NOTES:
- 
-    1. This configuration uses the mconf-based configuration tool.  To
-       change this configuration 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. Default toolchain:
-
-       CONFIG_HOST_WINDOWS=y                   : Builds under Windows
-       CONFIG_WINDOWS_CYGWIN=y                 : Using Cygwin
-       CONFIG_ARMV6M_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery for Windows
-
-    3. Serial Console.  A serial console is required to see the OS test
-       output.  The serial console is configured on UART1 which is available
-       on JP5:
-
-       UART1 RX signal (RXD1) is on PB.4, pin 8, and
-       UART1 TX signal (TXD1) is on PB.5, pin 9.

 CONFIGURATION
 =============
 
-  ostest
-  ------
-    This configuration directory, performs a simple OS test using
-    apps/examples/ostest.
-
-    NOTES:
-
-    1. This configuration uses the mconf-based configuration tool.  To
-       change this configuration 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. Uses the older, OABI, buildroot toolchain.  But that is easily
-       reconfigured:
-
-       CONFIG_ARMV7M_TOOLCHAIN_BUILDROOT=y : Buildroot toolchain
-       CONFIG_ARMV7M_OABI_TOOLCHAIN=y      : Older, OABI toolchain
-

     This is identical to the nsh configuration below except that NuttX

 -----------------------------
 
-  ostest:
-    This configuration directory, performs a simple OS test using
-    apps/examples/ostest.
-
-    NOTES:
-
-    1. The serial console is on UART1.  Therefore, you will need an external
-       RS232 driver or TTL serial-to-USB converter.  The UART1 TX and RX
-       pins are available on:
-
-           TX  -- Pin 53: U1TX/RF8
-           RX  -- Pin 52: U1RX/RF2
-
-       Power for the converter is available from the power point connector:
-
-          GND -- POWER POINT: GND
-          Vcc -- POWER POINT: Vdd (3.3V) -- Or P32_VBUS (+5V)
-                 Or +5V from a USB PC port.
-
-       The serial console is configured for 115200 8N1 by default.
-
-    2. By default, this configuration uses an older Microchip C32 toolchain
-       for Windows (the newer ones seem to be incompatible) and builds under
-       Cygwin (or probably MSYS).  That can easily be reconfigured, of course.
-
-       Build Setup:
-         CONFIG_HOST_WINDOWS=y                     : Builds under Windows
-         CONFIG_WINDOWS_CYGWIN=y                   : Using Cygwin
-
-       System Type:
-         CONFIG_MIPS32_TOOLCHAIN_MICROCHIPW_LITE=y : Older C32 toolchain
-
   nsh:
     This configuration directory holds configuration files tht can
     be used to support the NuttShell (NSH).

     Bottom line:  Not ready for prime time.
 
-  ostest:
-
-    This configuration directory, performs a simple OS test using
-    examples/ostest.
-
-    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.  These are the relevant configuration options
-       the define the NOR FLASH configuration:
-
-       CONFIG_SAMA5_BOOT_CS0FLASH=y            : Boot from FLASH on CS0
-       CONFIG_BOOT_RUNFROMFLASH=y              : Run in place on FLASH (vs copying to RAM)
-
-       CONFIG_SAMA5_EBICS0=y                   : Enable CS0 external memory
-       CONFIG_SAMA5_EBICS0_SIZE=134217728      : Memory size is 128KB
-       CONFIG_SAMA5_EBICS0_NOR=y               : Memory type is NOR FLASH
-
-       CONFIG_FLASH_START=0x10000000           : Physical FLASH start address
-       CONFIG_FLASH_VSTART=0x10000000          : Virtual FLASH start address
-       CONFIG_FLASH_SIZE=134217728             : FLASH size (again)
-
-       CONFIG_RAM_START=0x00300400             : Data stored after page table
-       CONFIG_RAM_VSTART=0x00300400
-       CONFIG_RAM_SIZE=114688                  : Available size of 128KB - 16KB for page table
-
-       NOTE:  In order to boot in this configuration, you need to close the
-       BMS jumper.
-
-    4. Data resides in ISRAM, but can be moved to SDRAM as described above
-       under "SDRAM Data Configuration."

-    This configuration directory, performs a simple OS test using
-    apps/examples/ostest.
-
-    NOTES:
-
-    1. This configuration uses the mconf-based configuration tool.  To
-       change this configuration using that tool, you should:
-
-       a. Build and install the mconf tool.  See nuttx/README.txt and
-          misc/tools/
-
-       b. Execute 'make menuconfig' in nuttx/ in order to start the
-          reconfiguration process.
-
-    2. Default toolchain:
-
-       CONFIG_STM32_CODESOURCERYL=y  : CodeSourcery under Linux / Mac OS X
-
-    3. By default, this project assumes that you are *NOT* using the DFU
-       bootloader.

 Where <subdir> is one of the following:
 
-  ostest:
-  ------
-    This configuration directory, performs a simple OS test using
-    apps/examples/ostest.
-
-    NOTES:
- 
-    1. This configuration uses the mconf-based configuration tool.  To
-       change this configuration 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. Default toolchain:
-
-       CONFIG_HOST_WINDOWS=y                   : Builds under Windows
-       CONFIG_WINDOWS_CYGWIN=y                 : Using Cygwin
-       CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery for Windows
-
-    3. By default, this project assumes that you are *NOT* using the DFU
-       bootloader.
- 
-    4. If you use the Atollic toolchain, then the FPU test can be enabled in the
-      examples/ostest by adding the following your NuttX configuration file:
-
-      -CONFIG_ARCH_FPU=n              : Enable FPU support
-      +CONFIG_ARCH_FPU=y
-
-      -CONFIG_STM32_CODESOURCERYW=y   : Disable the CodeSourcery toolchain
-      +CONFIG_STM32_CODESOURCERYW=n
-
-      -CONFIG_STM32_ATOLLIC_LITE=n   : Enable *one* the Atollic toolchains
-       CONFIG_STM32_ATOLLIC_PRO=n
-      -CONFIG_STM32_ATOLLIC_LITE=y   : The "Lite" version
-       CONFIG_STM32_ATOLLIC_PRO=n    : The "Pro" version
-
-      -CONFIG_INTELHEX_BINARY=y       : Suppress generation FLASH download formats
-      +CONFIG_INTELHEX_BINARY=n       : (Only necessary with the "Lite" version)
-
-      -CONFIG_HAVE_CXX=y              : Suppress generation of C++ code
-      +CONFIG_HAVE_CXX=n              : (Only necessary with the "Lite" version)
-
-      -CONFIG_SCHED_WAITPID=y         : Enable the waitpid() API needed by the FPU test
-      +CONFIG_SCHED_WAITPID=n
-
-      The FPU test also needs to know the size of the FPU registers save area in
-      bytes (see arch/arm/include/armv7-m/irq_lazyfpu.h):

-  ostest:
-  ------
-    This configuration directory, performs a simple OS test using
-    apps/examples/ostest.
-
-    NOTES:
-
-    1. This configuration uses the mconf-based configuration tool.  To
-       change this configuration 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. Default toolchain:
-
-       CONFIG_STM32_CODESOURCERYL=y  : CodeSourcery under Linux / Mac OS X
-
-    3. By default, this project assumes that you are *NOT* using the DFU
-       bootloader.
-
-    4. If you use the Atollic toolchain, then the FPU test can be enabled in the
-      examples/ostest by adding the following your NuttX configuration file:
-
-      -CONFIG_ARCH_FPU=n              : Enable FPU support
-      +CONFIG_ARCH_FPU=y
-
-      -CONFIG_STM32_CODESOURCERYW=y   : Disable the CodeSourcery toolchain
-      +CONFIG_STM32_CODESOURCERYW=n
-
-      -CONFIG_STM32_ATOLLIC_LITE=n   : Enable *one* the Atollic toolchains
-       CONFIG_STM32_ATOLLIC_PRO=n
-      -CONFIG_STM32_ATOLLIC_LITE=y   : The "Lite" version
-       CONFIG_STM32_ATOLLIC_PRO=n    : The "Pro" version
-
-      -CONFIG_INTELHEX_BINARY=y       : Suppress generation FLASH download formats
-      +CONFIG_INTELHEX_BINARY=n       : (Only necessary with the "Lite" version)
-
-      -CONFIG_HAVE_CXX=y              : Suppress generation of C++ code
-      +CONFIG_HAVE_CXX=n              : (Only necessary with the "Lite" version)
-
-      -CONFIG_SCHED_WAITPID=y         : Enable the waitpid() API needed by the FPU test
-      +CONFIG_SCHED_WAITPID=n
-
-      The FPU test also needs to know the size of the FPU registers save area in
-      bytes (see arch/arm/include/armv7-m/irq_lazyfpu.h):
-
-      -CONFIG_EXAMPLES_OSTEST_FPUSIZE=(4*33)
-
-  ostest-fpu
-  ----------
-
-    This is essentially the same as the as the ostest configuration but
-    additionally enables the FPU.  Contributed by David Alessio.

      http://www.nuttx.org/doku.php?id=wiki:graphics:nxgraphics for a description
      of the fat, flat line bug.
 
-  ostest:
-  ------
-    This configuration directory, performs a simple OS test using
-    apps/examples/ostest.
-
-    NOTES:
-
-    1. This configuration uses the mconf-based configuration tool.  To
-       change this configuration 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. Default toolchain:
-
-       CONFIG_STM32_CODESOURCERYL=y  : CodeSourcery under Linux / Mac OS X
-
-    3. By default, this project assumes that you are *NOT* using the DFU
-       bootloader.
-
-    4. If you use the Atollic toolchain, then the FPU test can be enabled in the
-      examples/ostest by adding the following your NuttX configuration file:
-
-      -CONFIG_ARCH_FPU=n              : Enable FPU support
-      +CONFIG_ARCH_FPU=y
-
-      -CONFIG_STM32_CODESOURCERYW=y   : Disable the CodeSourcery toolchain
-      +CONFIG_STM32_CODESOURCERYW=n

-      -CONFIG_STM32_ATOLLIC_LITE=y   : The "Lite" version
-       CONFIG_STM32_ATOLLIC_PRO=n    : The "Pro" version
-
-      -CONFIG_INTELHEX_BINARY=y       : Suppress generation FLASH download formats
-      +CONFIG_INTELHEX_BINARY=n       : (Only necessary with the "Lite" version)
-
-      -CONFIG_HAVE_CXX=y              : Suppress generation of C++ code
-      +CONFIG_HAVE_CXX=n              : (Only necessary with the "Lite" version)
-
-      -CONFIG_SCHED_WAITPID=y         : Enable the waitpid() API needed by the FPU test
-      +CONFIG_SCHED_WAITPID=n
-
-      The FPU test also needs to know the size of the FPU registers save area in
-      bytes (see arch/arm/include/armv7-m/irq_lazyfpu.h):

-
-    NOTES:
-
-    1. This configuration uses the mconf-based configuration tool.  To
-       change this configuration using that tool, you should:
-
-       a. Build and install the mconf tool.  See nuttx/README.txt and
-          misc/tools/
-
-       b. Execute 'make menuconfig' in nuttx/ in order to start the
-          reconfiguration process.
-
-    2. Default toolchain:
-
-       CONFIG_STM32_CODESOURCERYL=y  : CodeSourcery under Linux / Mac OS X

-    1. By default, this configuration uses an older Microchip C32 toolchain

-    1. This configuration uses the mconf-based configuration tool.  To
-       change this configuration using that tool, you should:
-
-       a. Build and install the kconfig-mconf tool.  See nuttx/README.txt

-    Description.
-    ------------
-    This configuration directory, performs a simple OS test using
-    apps/examples/ostest.
-
-    NOTES:
-    ------ 
-    1. This configuration uses the mconf-based configuration tool.  To
-       change this configuration 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. Serial Output.
-
-       The OS test produces all of its test output on the serial console.
-       This configuration has UART1 enabled as a serial console.
