1、1.Make编译uboot出错：…………board.c:138:error:inlinefunction'coloured_LED_init'cannotbedeclaredweakboard.c:140:error:inlinefunction'red_LED_on'cannotbedeclaredweakboard.c:142:error:inlinefunction'red_LED_off'cannotbedeclaredweakboard.c:144:error:inlinefunction'green_LED_on'cannotbedeclaredweakboard.c:146:er

3、植操作这个错误将消失。或者注释掉出错行。****挂载文件系统时候的错误：************…………TCPcubicregisteredNET:Registeredprotocolfamily17drivers/rtc/hctosys.c:unabletoopenrtcdevice(rtc0)VFS:UnabletomountrootfsviaNFS,tryingfloppy.VFS:Cannotopenrootdevice"nfs"orunknown-block(2,0)Pleaseappendacorrect"root="bootoption;herearetheavailablepa

6、on.a(main.o)不使用新的4.4.3版本的编译工具，改为以前的3.4.5版本的arm-linux-gnu-gcc.****编译好的uboot下载到板子上没有任何的输出内容？？？************可能是自动拷贝的4KB代码不能完成自启动，更改根目录下的Makefile文件：将一行改为如下形式：__LIBS:=$(subst$(obj),,$(LIBBOARD))$(subst$(obj),,$(LIBS)interrupts.c:184:3:#error"tbclknotconfigured"interrupts.c:Infunction`get_tbclk':interrupts
