SABRE Touchscreen not working (MCIMX6Q-SDP)

Question asked by Matthias Bilger on Jan 29, 2015

Dear community,

 

I have some troubles regarding the touchscreen on the Sabre platform. I have the evaluation kit from Freescale including the 10" display as mentionen in the topic.

I have created a small application that tries to read events from the touchscreen device. This works only sometimes.

- Sometimes after startup the touchscreen works for a few seconds, sometimes it does not work at all

- If it works it suddenly stops working. The system is still responsive, but there are no more events

- I do not have a gui running.

- I'm using a yocto build environment

 

I attached the kernel config.

 

Any Ideas? Anything someone can give me a hint?
