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?

Debug file attached

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.

Hi Frank

Thanks your reply
Although WaveShare display has response
to my two fingers, it seems abnormal.
For single finger touch, no any response.

ODROID VU7 plus issue already fixed?

If WaveShare cannot be fix,
I can only turn back to ODROID VU7 plus

Still waiting

How do I enable the touch screen? Mine isn't a WaveShare specifically, but is no-name and looks very similar in design.

Do I have to enable something or download a driver to get the USB touch screen to work?
