I’m trying to use the HDMI display adapter plugged into the Colibri SoM header to mirror the images displayed on our products LCD. We have a customized device tree for our carrier board design, but nothing is appearing. Are there certain settings that have to be passed to the kernel to enable the HDMI output on the board? Custom DTS/DTB settings?
Hi @dwooldridge,
Could you please test this article?
There you’ll see some frame buffer configurations. You can try to set one frame buffer as output to your HDMI and another frame buffer for LCD.
If your HDMI and LCD interfaces are already enabled on your device tree, you don’t need to change it.
Please, check if this solves your problem.
Best regards,
Hiago.
