通过uboot如何引导编译好的sylixos

我爱下载

我编译了mini2440的bspmini2440.bin，我通过uboot将bin文件下载到ram的起始地址，然后跳转到起始地址，不能正确引导出现如下错误： 这是怎么回事

t_boot 内核线程还没有到初始化标准文件描述符时，崩溃了， 你把内核 log 在启动参数中打开，看看内核初始化到哪里出现了错误。klog=yes

我在编译uboot的时候，发现地址30001000是uboot的全局变量存储地址，当我下载编译后的镜像文件时把这段全局变量地址给覆盖了，我修改了bspmini2440的内存起始地址为30010000跳过前面一段地址后，问题得到解决，可以正常启动了。
