Help about MPC823 Video and Cache

[Shuangjun Zhu]

Hello, everyone

I'm using kernel version 2.2.13 on my MPC823 FADS board
to display on TV. I have a problem:

After the system boot up, the text on the TV flicker fiercely out,
if I disable the I-Cache throught the EST visionProbe tool,
TV will not flicker out again.
Of course, if I disable the cache when the system boot up,
TV display OK.
So there is some relation between the cache and the video, I guess.


Do you have any suggestion?
Thanks in advacned!

BRs,
Shuangjun
