README ^^^^^^ 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
