Hi, all
I meet a very difficult problem about ppc linux run on MPC5200. my
linux version is 2.4.18.
When i run my application for some time, the linux operation system
will reset to jump to the uboot and restart linux,. When it happen, I can
capture hreset and sreset signal using oscillograph. Additional, when linux
reset , it have two results: one is enter machine check exception and some
debug information is outputted, the other is nothing is to be outputted. The
debug information is following:
Machine check in kernel mode.
Caused by (from SRR1=41030): Transfer error ack signal
Oops: machine check, sig: 7
