在板子上可以运行的uClinux在skyeye上出了问题
我的uClinux原来是在44b0上运行的，而且没有问题在skyeye 1。2上 刚开始解压信息，初始化信息都正确，
输出了很多东西：

永远死了，是不是skyeye的44b0moni的io读写有问题啊？
请高手帮忙解答一下。
谢谢！ I am also interesting about this issue.I did a workaround last year. Maybe that is a bug of SkyEye.
modify your kernel sourcefileinclude/asm-arm/processor.h :
regs->ARM_cpsr = USR26_MODE;
to
regs->ARM_cpsr = USR_MODE;
That maybe can run 44b0.
