[U-Boot-Users] Memory Size issue @ MPC83xx

Wolfgang,

thanks for the hint - unfortunately the issue is not solved, yet.
Obviously I've missed something...

U-boot is working fine with both 256MB and 512MB RAM.
The kernel crashes with memory > 256MB.

Do I need to set up a 2nd BAT for mapping main memory before booting
linux in any case ?

Do you now of any kernel related issues/missing configs ?
I know this is off-topic to this list - but maybe you can help me out.


regards,
Andre
