RE: MPC8245 custom board, Linux 2.4 kernel hangs after uncompressing

I forgot to mention this...u should do a soft reset. If you go about =
powering off and on your board your buffer will be flushed. But for a =
soft reset the contents will be retained.

1. Check your log buffer...your console may not be
initialized yet so all your printk are logged at a=20
particular memory location. Checkout the
System.map file in the Linux folder for "log_buf".
The address that you have there subtract it with=20
the kernel base address. Then in view your
memory at that location. We used U-Boot so we gave
the command
=09
	md <log_buff address>

Interesting to me as well. I also have such a similar
problem. But I wanna to know how I can return to=20
u-boot with software workaround after kernel hanging.
At least, I must power-off and power-on my target to
get back to u-boot console. If so, the last kernel=20
printk message would lost IMHO.

Thanks,

Sam
