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
