ARM/C5471-specific Configuration Options
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
CONFIG_ARCH - Identifies the arch/ subdirectory. This should
|
|
be set to:
|
|
|
|
CONFIG_ARCH=arm
|
|
|
|
CONFIG_ARCH_name - For use in C code:
|
|
|
|
CONFIG_ARCH_ARM=y
|
|
|
|
CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
|
|
|
|
CONFIG_ARCH_CHIP=c5471
|
|
|
|
CONFIG_ARCH_CHIP_name - For use in C code
|
|
|
|
CONFIG_ARCH_CHIP_C5471
|
|
|
|
CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
|
|
hence, the board that supports the particular chip or SoC.
|
|
|
|
CONFIG_ARCH_BOARD=c5471evm (for the Spectrum Digital C5471 EVM)
|
|
|
|
CONFIG_ARCH_BOARD_name - For use in C code
|
|
|
|
CONFIG_ARCH_BOARD_C5471EVM (for the Spectrum Digital C5471 EVM)
|
|
|
|
CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
|
|
of delay loops
|
|
|
|
CONFIG_ENDIAN_BIG - define if big endian (default is little
|
|
endian)
|
|
|
|
CONFIG_ROM_VECTORS - should be defined for the C5471 because the
|
|
interrupt vectors are in ROM
|
|
|
|
CONFIG_DRAM_END - the size of installed DRAM. Unique to c5471
|
|
|
|
CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
|
|
have LEDs
|
|
|
|
CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
|
|
stack. If defined, this symbol is the size of the interrupt
|
|
stack in bytes. If not defined, the user task stacks will be
|
|
used during interrupt handling.
|
|
|
|
CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
|
|
|
|
C5471 specific device driver settings
|
|
|
|
CONFIG_SERIAL_IRDA_CONSOLE - selects the IRDA UART for the
|
|
console ant ttys0 (default is the modem UART).
|
|
CONFIG_UART_*_HWFLOWCONTROL - enables hardware flow control
|
|
CONFIG_UART_*_RXBUFSIZE - Characters are buffered as received.
|
|
This specific the size of the receive buffer
|
|
CONFIG_UART_*_TXBUFSIZE - Characters are buffered before
|
|
being sent. This specific the size of the transmit buffer
|
|
CONFIG_UART_*_BAUD - The configure BAUD of the UART. Must be
|
|
CONFIG_UART_*_BITS - The number of bits. Must be either 7 or 8.
|
|
CONFIG_UART_*_PARTIY - 0=no parity, 1=odd parity, 2=even parity
|
|
CONFIG_UART_*_2STOP - Two stop bits
|
|
|
|
C5471 Ethernet Driver settings
|
|
|
|
CONFIG_C5471_NET_STATS
|
|
CONFIG_C5471_ETHERNET_PHY={ETHERNET_PHY_LU3X31T_T64,ETHERNET_PHY_AC101L}
|
|
CONFIG_NET_C5471_AUTONEGOTIATION
|
|
CONFIG_NET_C5471_BASET100
|
|
CONFIG_NET_C5471_BASET10
|
|
|
|
defconfig
|
|
^^^^^^^^^
|
|
The default configuration file, defconfig, performs a
|
|
simple OS test using examples/ostest. This can be
|
|
configuration as follows:
|
|
|
|
cd tools
|
|
./configure.sh c5471evm
|
|
cd -
|
|
. ./setenv.sh
|
|
|
|
netconfig
|
|
^^^^^^^^^
|
|
This alternative configuration file, netconfig, may be used
|
|
instead of the default configuration (defconfig). This
|
|
configuration enables networking using the c5471's built-in
|
|
Ethernet interface. It uses examples/nettest to excercise
|
|
the TCP/IP network.
|
|
|
|
nshconfig
|
|
^^^^^^^^^
|
|
This configuration file builds NSH (examples/nsh) using the
|
|
TELNET server front end
|
|
|
|
dhcpconfig
|
|
^^^^^^^^^^
|
|
This configuration exercises the DHCP client of netutils/dhcpc
|
|
using examples/uip.
|
|
|
|
These alternative configurations can be selected by (using
|
|
uipconfig as example):
|
|
|
|
(Seleted the default configuration as show above)
|
|
cp config/c5471evm/uiponfig .config
|
|
