G'day to all.

BBB hardware: Revision A5C
Software: Debian 7.3 wheezy kernel 3.8.13-bone40.1 ( With 3.8 patch set )

LCD Testing:

7" inch resistive touchscreen LCD 4DCAPE-70T from 4D systems on the Beaglebone Black.

I used the TSLIB calibration tools as well as running LXDE. Cursor still jumps to bottom left of the screen.

With the same hardware set up, I installed the Android 4.2.2 (k3.8.13) image from
http://www.elinux.org/Beagleboard:Android port page.

LCD and touch works perfectly fine.

Are we sure this is a driver level issue or is Android using some other touchscreen driver or subsystem?

Best regards.

Vaughn
