Hi

console=ttyS0 is good but why again console=tty.
That might be the issue.
When u r paasing parameters from ppcboot, why console
is eqated two times.

U should only say console=ttyS0 , 9600

So console=tty is not correct............
Try out this...

Hi

quoted

From the inuts u have given it is very tough to

find

quoted

out. But let me ask u some of the questions.

1. One possiblity is that ur serial port is not
configured properly & u are not seeing any message
from the console port.

2. IF u are having the JTAG debugger find out the
value in Program conuter & see where it matches in
System.map.

So tell me the PC value then it might be possible

to

quoted

catch the problem

Thanx
