AM335x touchscreen issues

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Greetings,

I have been porting Linux to a new AM3554 based SoM and have found issues
with the touchscreen reporting touch releases repeatedly to userspace
without actually touching the screen when running ts_calibrate, ts_test
or other graphical touchscreen applications.

This started happening after updating pulling recent changes.

It has also been confirmed to be happening on the beagle bone black:

If you look further into this thread you will see a workaround patch that
I came up with:
http://www.spinics.net/lists/linux-iio/msg18583.html

Though this fix stops the reported events in userspace, interrupts are
still occuring repeatedly.

Does anyone have any suggestions beyond what I have done to remedy this
issue?

Regards,

Michael
