Hi Grant,
Thanks for your answer.
I have found in the System.map :
c020f0c4 b __log_buf
Is the address c020f0c4 relative to the .data segment?
I understand that when the system hangs I should type in the XMD window
stop.
Is there anyway to examine the memory from the XMD window? or should I
reload the u-boot and examine the memory from u-boot?
Best Regards
Mirek
