Hi,
Has anyone been able to get the cirrus 72xx LCD code sample to work
recently? I recompiled the code and checked the values for all of the
control registers in the Cirrus documentation. It looks correct but when I
initialize the ALPS LCD on my EP7211 board I get alot of garbage on the
screen. When I try to clear the screen by writing zeroes to 0xc0000000 my
program just hangs. Any ideas anyone?
Funny thing is that if I try to fill that memory region using cygmon I am
able to do it.
Thanks in advance...
Wilson
