i have also build a new image now but ts_calibrate doesnt work for me :-(
ts_calibrate
xres = 480, yres = 640
selected device is not a touchscreen I understand
Took 1 samples...
Top left : X = 0 Y = 0
Took 1 samples...
Top right : X = 0 Y = 0
Took 1 samples...
Bot right : X = 0 Y = 0
Took 1 samples...
Bot left : X = 0 Y = 0
Took 1 samples...
Center : X = 0 Y = 0
ts_calibrate: determinant is too small -- 0.000000
Calibration failed.
any ideas whats wrong?
but ts_test outputs something if i push the screen.
