Try it out, so you get used to is ;-) I wish it is not that hard,however I can not debug the kernel or ppcboot according the brief introduction in BDI manual.:( I want to watch r3,r4,r5,r6,r7 register when ppcboot transferring to kernel.Could you tell me how to get that? thanks a lot! > > > so I am seeking errors in blind. > > Just open your eyes, and thou shalt see :-) > > Wolfgang Denk > > -- > Software Engineering: Embedded and Realtime Systems, Embedded Linux > Phone: (+49)-8142-4596-87 Fax: (+49)-8142-4596-88 Email: wd@denx.de > Always leave room to add an explanation if it doesn't work out. > > > > ** Sent via the linuxppc-embedded mail list.
