@ -30,11 +30,72 @@ 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 only the serial NSH interfaces.
Configuration Options
^^^^^^^^^^^^^^^^^^^^^
In additional to the common configuration options listed in the
file configs/README.txt, there are other configuration options
specific to the LPC214x:
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
LPC2148 specific chip initialization
CONFIG_EXTMEM_MODE, CONFIG_RAM_MODE. CONFIG_CODE_BASE, CONFIG_PLL_SETUP,
CONFIG_MAM_SETUP, CONFIG_APBDIV_SETUP, CONFIG_EMC_SETUP,. CONFIG_BCFG0_SETUP,
CONFIG_BCFG1_SETUP, CONFIG_BCFG2_SETUP, CONFIG_BCFG3_SETUP, CONFIG_ADC_SETUP
LPC214X UART 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, 3=mark 1, 4=space 0
CONFIG_UARTn_2STOP - Two stop bits
LPC214X USB Configuration
CONFIG_LPC214X_USBDEV_FRAME_INTERRUPT
Handle USB Start-Of-Frame events.
Enable reading SOF from interrupt handler vs. simply reading on demand.
Probably a bad idea... Unless there is some issue with sampling the SOF
from hardware asynchronously.
CONFIG_LPC214X_USBDEV_EPFAST_INTERRUPT
Enable high priority interrupts. I have no idea why you might want to
do that
CONFIG_LPC214X_USBDEV_NDMADESCRIPTORS
Number of DMA descriptors to allocate in the 8Kb USB RAM. This is a
tradeoff between the number of DMA channels that can be supported vs
the size of the DMA buffers available.
CONFIG_LPC214X_USBDEV_DMA
Enable lpc214x-specific DMA support

^^^^^^
This configuration directory, performs a simple OS test using

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.
