ppc 85xx 内核编译 问题

prettyiceii

编译器： eldk
开发包版本：ppc-2008-04-01.iso
内核：2.6.22

在  make ARCH=powerpc CROSS_COMPILE=ppc_85xx- uImage  步时出错。

怎么没人说一个，自己顶一个。

上边的问题是在 menuconfig 的时候，去掉了floppy 的支持项解决。编译成功（当中有些警告，但还是过去了）。

之后载入目标板。

出现新的问题。

到这一步就停住了，等待解决。
猜想应该是串口设置问题，但还不知道怎么解决。

你的load address && entry point 确信对吗？

yidou

你mkimage的时候，-a  -e 参数？
还有bootcmd的参数设置。

问题出在编译时，少了有关串口的驱动。具体什么地方没有，还没搞清楚，现在的内核只是默认的。只选了芯片的型号。编译通过。起码内核可以跑了。
