Subject: [ECOS] LCD on EP7211
Date: Wed, 31 Jan 2001 14:43:00 -0000	[thread overview]
Message-ID: <005f01c08bd7$7a806c00$0b02a8c0@r2d2> (raw)

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
