README
^^^^^^
Each Neuros OSD configuration is maintained in a sudirectory and
can be selected as follow:
cd tools
./configure.sh ntosd-dm320/<subdir>
cd -
. ./setenv.sh
Where <subdir> is one of the following:
ostest
^^^^^^
This configuration directory, performs a simple OS test using
examples/ostest.
nsh
^^^
Configures the NuttShell (nsh) located at examples/nsh. The
Configuration enables both the serial and telnetd NSH interfaces.
nettest
^^^^^^^
This alternative configuration directory may be used to
enable networking using the OSDs DM9000A Ethernet interface.
It uses examples/nettest to excercise the TCP/IP network.
uip
^^^
This configuration file demonstrates the tiny webserver
at examples/uip.
udp
^^^
This alternative configuration directory is similar to nettest
except that is use examples/upd to exercise UDP.
Configuration Options
^^^^^^^^^^^^^^^^^^^^^
In additional to the common configuration options listed in the
file configs/README.txt, there are other configuration options
specific to the DM320:
CONFIG_ARCH - identifies the arch subdirectory and, hence, the
processor architecture.
CONFIG_ARCH_name - for use in C code. This identifies the
particular chip or SoC that the architecture is implemented
in.
CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
CONFIG_ARCH_CHIP_name - For use in C code
CONFIG_ARCH_BOARD - identifies the configs subdirectory and, hence,
the board that supports the particular chip or SoC.
CONFIG_ENDIAN_BIG - define if big endian (default is little endian)
CONFIG_ARCH_BOARD_name - for use in C code
CONFIG_BOARD_LOOPSPERMSEC - for delay loops
CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to lpc2148.
CONFIG_DRAM_SIZE - Describes the internal DRAM.
CONFIG_DRAM_START - The start address of internal DRAM
CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
DM320 specific device driver settings
CONFIG_UARTn_SERIAL_CONSOLE - selects the UARTn for the
console and ttys0 (default is the UART0).
CONFIG_UARTn_RXBUFSIZE - Characters are buffered as received.
This specific the size of the receive buffer
CONFIG_UARTn_TXBUFSIZE - Characters are buffered before
being sent. This specific the size of the transmit buffer
CONFIG_UARTn_BAUD - The configure BAUD of the UART. Must be
CONFIG_UARTn_BITS - The number of bits. Must be either 7 or 8.
CONFIG_UARTn_PARTIY - 0=no parity, 1=odd parity, 2=even parity
CONFIG_UARTn_2STOP - Two stop bits
DM320 USB Configuration
CONFIG_DM320_GIO_USBATTACH
GIO that detects USB attach/detach events
CONFIG_DM320_GIO_USBDPPULLUP
GIO connected to D+. Support software connect/disconnect.
CONFIG_DMA320_USBDEV_DMA
Enable DM320-specific DMA support
