I wrote that it could be a problem. I do not know much about
your system and U-Boot port and do not know exactly what you
meant by "damaged screen output" and when exactly it happens,
so I can only speculate.

This is another issue then. Can you test read/write access to
the frame buffer area by available memory commands "cp", "md",
"mm", "cmp"? Can you also verify that reading from frame buffer
area by using these memory commands is not working?
Thanks,
Anatolij
