Hi,

 

I have been working on Rocko build from fsl-community-bsp, since last few days and able to complete the builds for our various devices which uses imx6UL and imx6Solo processors.

 

During testing these builds, I have encountered an issue with touch screen calibration for iMX6UL based build. So i have again tried the same build for imx6ulevk and tested on imx6UL EVK and encountered the same issue, below are the details

 

Machine: imx6ulevk

Image: core-image-x11

 

The issue I have observed on the device is, Xorg is unable to calibrate the touchscreen, I don’t know what has changed but it is unable to calibrate, below is the log
