We want to use our display in "portrait" mode. Our command in startx is:
Xfbdev -kb -screen 800x480@90 -mouse tslib,2,device=/dev/input/ts0 &
The display itself works fine, but ts_calibrate seems to ignore the rotate parameter, always running in "portrait" (non-rotated) mode. So therefore the touch screen doesn't work properly when @90 rotation is used. Without the rotate parameter, the touch screen work fine.
Any suggestions on how to get ts_calibrate working correctly with the display "rotated" on the i.MX28 EVM?
