PiTFT 3.5" touch screen not working

[palon7]

Hi.

I was downloaded image from https://learn.adafruit.com/adafruit-pit ... sy-install, and install to raspberry pi.
Display is working, but touch screen is not working.

I type "sudo evtest /dev/input/touchscreen", but return:

Code: Select all

evtest: No such file or directory

Part of dmesg:

I tried reinsert flex cable(http://forums.adafruit.com/viewtopic.php?f=50&t=66668), but not changed.

Try removing power, wait a few minutes, then restart the Pi, then post up the output of dmesg again - we'll take a look :)

OK. I try this and show:

hmm, can you take a photo of the back of the PiTFT 3.5"? just wanna see if anything clearly is amiss :)

[palon7]

OK.

[adafruit2]

ok lets get you another one - email support@adafruit with a link to this thread! :)
