[U-Boot-Users] boot kernel from u-boot

[U-Boot-Users] boot kernel from u-boot

[Reeve Yang]

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 ...

Resetting the board.

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.
