Thanks for your reply. I will try it tomorrow.
after a few try this afternoon, the situation getting worse and worse. I
wonder my screen is faulty.
at the beginning, i can't see 'touchscreen0' in /dev/input. but when i boot
gumstix WITHOUT 2Gb SD card, i can see 'touchscreen0', and 'ts_test' was
working properly. i can see all feature on the screen.
then, I have used the following commands to update u-boot.
$ nand erase 240000 20000
i can see the 'touchscreen0' in /dev/input, but the screen had nothing on
it. when i try 'ts_test', i can see the program picked up the position when
i touched the screen (i used anther linux pc connects gumstix through
console port), but i can't see anything. the back light of screen is ON, but
and now, after i plug in the power, the back light will turn on and quite
bright. and nothing on the screen, just light.
is my screen dead? i unplug the power cable, and will give it a try
Does anyone have the same experience?
