Hi,

when I use the MCF5329 with a resolution of 800x480, I have the follow problem:
if the frame buffer is black (ex.: "cat /dev/zero > /dev/fb0") the throughput over ethernet is about zero, it's diffucult to ping the board. Instead if the frame buffer is colored or white better the throughput is ok, we arrived about to 10 Mbit/s.
Why there is this difference?

Thanks
Bye
