I bet it didn't work with your old kernel either. 0x10000 is just 64 kB - this is _never_ enough for an uncompressed Linux kernel. You will overwrite your kernel while uncompressing it, which crashes the system. Use a higher load address, somthing like 0x200000. > In the PPCBoot guide(FAQ section),it mentioned > 2 possible causes,wrong bdinfo and clocks_in_mhz > I do check it and feel nothing wrong,however > nothing yet. You have to _unset_ clocks_in_mhz for a 2.4.20-pre2 kernel. > I have a BDI2000,but I think I should debug the bootm > part of ppcboot,however someone says it is quite > difficult to do so( at least for me). Well, it's not _that_ difficult. Try it out, so you get used to is ;-) > so I am seeking errors in blind.
