How can IMX8MQ specify a resolution through a firmware file?
We are using the IMX8MQ chip with kernel version 5.10.72. Here is a reference link.

We also want to try reading the. bin file to force HDMI output, but we did not see the/Documentation/EDID/directory for kernel5.10.72. Is there any other modification method? Thank you.

Hi, @ximenbingmeng 

You can manually build this firmware.
Reference code is attached, you can directly use "make" command to create firmware such as 1280x1024.bin
Then you need to enable the CONFIG "CONFIG_DRM_LOAD_EDID_FIRMWARE" in make menuconfig. Other steps just follow what that blog says would be ok.
