［求助］linux2.6内核在lubbock下的移植

yaoxinyong

现在我的内核已经进行到这一步，应该是redboot rom的问题，我的板子根本没有这个东西，他却要检测，检测不到就错了，而且配置文件里关于redboot 的东西我都注释掉了

我搜索了好些日子，发现在lubbock下作移植的文档一个都没有，这是怎么回事呢

难道没人用过这个板子嘛，说也奇了

You are booting from the NFS, right?

The info above saying it can't find the bootloader at 0x0. Have you write any into this block?
