Hi!
I'm using an kernel 2.6.23.1 cuImage.85xx target and an u-boot from last week's git (which seems to work fine) on an mpc8540ads compatible board.
I just tried to follow: http://www.denx.de/wiki/view/DULG/LinuxPostMortemAnalysis because of no console output.
But no matter what address I try to figure out to dump __log_buf, it seems that u-boot wipes my memory during POST, so I cannot get anything @ __log_buf.
md 003b2ea8 (where my __log_buf points) 003b2ea8: deadbeef deadbeef deadbeef ........
I am pretty sure that only my console got stuck since my harddisks (on PCI) seems to get initialized (some noise and led activity from the HDDs) and the system reboots automatically after approx. 180 seconds due to the usual minor problems.
So, there are some questions:
Is u-boot wiping my memory during POST?
How can I disable that?
What are the default console settings to get a console on ttyS0?
Regards,
