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
|
