How to trace u-boot
Would you please teach me how to setup the config file or someting else, so I can debug U-BOOT cold in SkyEye.Thanks a lot The image in binary format do not contain any debug information. So it can not be debug by gdb. You can try to compile u-boot to elf format.Then if you use SkyEye below 1.0 version, you can type:
skyeye u-boot.elf
if you use skyeye above 1.0 version, you can tyoe:
skyeye -e u-boot.elf I use a config file to start u-boot with a binary file, it should be the same as skeyeye -e u-boot.elf, but the u-boot get executed when skyeye starts, so I can debug the binary from the first instruction. I use u-boot-1.2 Skyeye Wiki has a good tutorial on u-boot.

In the interface of skyeye, input: (For Skyeye1.0, this step shoul be ignored and u-boot will start directly.)
target sim
run
At this time , the interface and prompt of u-boot can be saw and then when inputting ?help?, all commands in u-boot can be showed or when inputting ?version?, the current u-boot version can be displayed etc.
我说怎么调试不了U-BOOT呢。
为什么自作聪明的自动运行U-BOOT呢？这样不就没有办法调试boot loader了吗！
