Scott,
are you talking about a possible hardware problem or misbehaving code ?
Does it look like something gets overwritten during initrd
extraction/movement ?
The system has 512MB RAM which means that we need 2 BAT regs to map the
memory. I've found comments in Freescale u-boot header files that
currently a max of 256MB is supported. I never understood why ? Could
this problem be related to this ?
Do I need to supply reserved memory regions ? I thought u-boot is doing
so for initrd and the kernel don't need it ...
I'll rebuild u-boot with 256MB memory size and do an extra run with
memory test - just to make sure.
Any hints where to look else ?
regards,
Andre
