Hi Shawn,

So what is the solution?

BTW, I am using 2.4.18.

Thanks a lot!

[U-Boot-Users] System hangs when Linux is loaded

[Frank Young]

Hi,

I have a Walnut board with ppc405. I have manged to install u-boot on the 
board. I can download linux image (I am using Monta Vista one) too. But when 
I tried to use "bootm", the system hanged after showing
"## Transferring control to Linux (at address 00000000) ..."

The following is the dump of serial console output. The uImage-uncomp is the 
uncompressed linux image created with tools/mkimage, as explained in README 
file. Does anyone have the same problem?

Thanks!
Frank

It could be clocks_in_mhz that causes the problem if you're using kernel
older than 2.4.11 if I'm not mistaken.
