[Invalid] - Rock64 HDMI 1024x600 resolution support

Question

I have Rock64 board with latest Armbian Focal flashed on it. I want to use it with this HDMI display by Waveshare: https://www.waveshare.com/wiki/7inch_HDMI_LCD_(H)_(with_case)
Now, when I connect it to Rock64 it runs as 1080p downscaled by HDMI controller on display, resulted image is garbage, even though it is present. As was discussed here: https://forum.armbian.com/topic/10071-tinker-board-hdmi-resolutions-do-not-all-work/ current kernel/u-boot doesn't have required video mode to run this display properly.

I tried to set required mode with xrandr but with no success.

Can anyone help me to figure out how to patch kernel/u-boot to get this thing work properly? And what exactly is setting video mode kernel or u-boot? I've found where video modes are set in u-boot source, but I suspect that adding required video mode there won't be enough, am I right?

Your issue report is invalid for one or multiple reasons (non-exhaustive enumeration):

 

  • it has been stated at the wrong place
  • it lacks fundamental requested data
  • it could have been easily solved by a quick search and/or reading documentation
  • unsupported userspace/image/SBC

 

Since you refused to use the bug reporting form carefully and follow the information there as you have been asked for we have no intention to further investigate.

Please add missing information if applicable.
