10.1 Waveshare

Not sure why but this screen will not work unless I unplug and replug the HDMI cord.

Using v 4.5

This should already have support:
viewtopic.php?f=51&t=15495&start=50#p152377

VID: 0eef
PID 0005

VID and PID are related to the touchscreen, so it should not the reason why your display does not work.
Would you let us know what's the version running on your ODROID-C2 and capture the kernel message if you can?

OK, I think I solved the 1st part of the issue, I changed

setenv display_autodetect "true"
setenv disablehpd "true"

2nd issue is that the touchscreen crashes after a few touches.

dmesg output spams :

[ 361.794738@0] hid-multitouch 0003:0EEF:0005.0003: can't reset device, dwc2_b-1.1/input0, status -32

When I plugin the touch usb.

Which means that ODROID-C2 fails to reset the touchscreen on your display module. Since ODROID-VU-7 also use the same chipset (0EEF:0005), it would not be the driver problem I think. Can you check if power is properly supplied?

Yes, I have checked and changed multiple power supplies. I am getting 5.1 v on 5v Pin and 3.23 v on 3.3v Pins

When i connect the Waveshare Touch - The voltage on pin drops to 4.7 on 5V pin and to 2.94 on 3.3v Pins

Do you also have the voltage drop problem when the touch screen is connected?

Change "disable_vu7" option in your boot.ini file.
