[U-Boot-Users] boot kernel from u-boot
My customized board has MPC8345E (almost same as mpc8349) processor and 128M sdram. Now we're trying to boot kernel from u-boot, I downloaded kernel image on locate 0xff300000, and I verified the flash contents which are written successfuly. However, when I try to boot it, it prints some traceback then reset.
=> go 0xff300000 ## Starting application at 0xFF300000 ... NIP: FF300000 XER: 00000000 LR: 0FFE17A8 REGS: 0f5d0c60 TRAP: 0700 DAR: 100D3000 MSR: 0002b002 EE: 1 PR: 0 FP: 1 ME: 1 IR/DR: 00

Could anyone give some hints what could be problem? Does code enter kernel or still in u-boot? How to decode traceback on linux? objdump?
Thanks.

you need to upload uImage and boot it via 'bootm'
Enn, interesting. What's the difference then?
I tried to use bootm, now I don't say exception, but system just hangs.

"bootm" works (assuming you have a working kernel image), while "go" cannot work.

Sp you have problems with your kernel port / configuration.
