本文解决编译过程中出现的弱内联函数声明错误问题，通过注释掉特定代码行来避免错误，确保编译过程正常进行。

打印的错误信息如下：

board.c:1: warning: target CPU does not support interworking
board.c:125: error: inline function 'coloured_LED_init' cannot be declared weak
board.c:127: error: inline function 'red_LED_on' cannot be declared weak
board.c:129: error: inline function 'red_LED_off' cannot be declared weak
board.c:131: error: inline function 'green_LED_on' cannot be declared weak
board.c:133: error: inline function 'green_LED_off' cannot be declared weak
board.c:135: error: inline function 'yellow_LED_on' cannot be declared weak
board.c:137: error: inline function 'yellow_LED_off' cannot be declared weak
make[1]: *** [board.o] Error 1
make[1]: Leaving directory `/opt/FriendlyARM/u-boot-2008.10/lib_arm'
make: *** [lib_arm/libarm.a] Error 2

解决方法：如图注释掉相应行
