Hi Gary,

Next problem - I have no video, neither with HDMI nor 7" LCD
Ideas?
Any progress with this (no video at all)? I've tried the
latest Boundary Devices kernel (b76cf1c04) whose comment
implies this should be fixed, but still no-go.
For completeness, here are some relevant messages at boot:
Kernel command line: enable_wait_mode=off

video=mxcfb1:dev=lcd,CLAA-WVGA,if=R

What silicon version are you running? As mentioned in Gary Bisson's
thread earlier, there are some known issues with TO 1.0 and HDMI.
My SabreLite is rev 1.0

These messages above match what Gary Bisson says he has a patch for...
And I just pushed a patch for the RGB display error below:
mxc_sdc_fb fb.28: NO mxc display driver found!
https://github.com/boundarydevices/linux-imx6/commit/0d7db21a8e6bc028209438ae3919907c177f348a
Yes, I thought I already had that applied. I'll check again.
Thanks
