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.

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
|

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.
