Hi smallfat,

my WaveShare display is broken, so i'm unable to test it.
Please post your debug data, maybe it helps to solve the issue.

Is your Display Ver. 2.1?

Hi Frank,

Refer to touch screen no function of WaveShare 7" (C) ver 2.1
Debug file attached

http://pastebin.com/Yak6e0PT

After above debug capture, I disable watchdog and change display zoom to 0.85.
when i use two fingers to touch screen, screen changed to blank (all white color)

Even I unplug and plug USB cable, it cannot be recovered.

So your touch is working!
I have no idea what your problem is.
Your debug data looks good.

I'm trying to get a new image (ODROID C2) ready within the next 2 weeks.
