[Jetson nano] How to output the specified resolution to a display without EDID

Sorry for the difficult English.
I want to output the specified resolution via HDMI to a display that has no EDID at all.
I understand that jetson nano cannot change modes using xrandr.
You can also modify the source code such as kernel, so please tell me a good way.
The kernel version is “4.9.140-tegra”.

You can enable the use_fallback in edid.c and rebuild the kernel image.

This function is using hardcoded value EDID.

You can find the source code here.

The problem has been solved.
Thank you.
