Tool/software: Linux
hi
I have a beaglebone black. I download the am335xSDK 08_00_00_00 installer on my virtual box (ubutun). Then I use the "creat-sdcard.sh" to install the pre-built image. I insert it to the BBB and it boots, and the matrix GUI shows up on the screen.
But the touch screen doesn't work, I can only move the mouse by using a USB mouse.
There is no /dev/input/touchscreen.
There is a file "pointercal" under /etc, and I do the following:
# ./matrix-gui-2.0 stop
# export TSLIB_CALIBFILE=/etc/pointercal
# ts_calibrate
And the output is :
root@am335x-evm:/etc# ts_calibrate
xres = 1024, yres = 768
tslib: Selected device is not a touchscreen (must support ABS and KEY event types)
Took 3 samples...
Top left : X = 0 Y = -1225414960
Took 3 samples...
Top right : X = 0 Y = -1225414960
Took 3 samples...
Bot right : X = 0 Y = -1225414960
Took 3 samples...
Bot left : X = 0 Y = -1225414960
Took 3 samples...
Center : X = 0 Y = -1225414960
ts_calibrate: determinant is too small -- 0.000000
Calibration failed.
