[Openpvrsgx-devgroup] openpvrsgx-devgroup Digest, Vol 11, Issue 16

Sat Oct 24 13:54:47 CEST 2020

Hi,
Sorry for being late to the party, I was suplosed to inform you earlier.
The thing is if I load the kernel with CedarView kernel module, there is a
resolution problem. I cannot get past 800*600. To be noted I am using
Debian buster (10.6)
Thanks,
Alif
