[yocto] [yocto-rocko] : fsl-community-bsp X11 build touch screen calibration issue on iMX6UL

[Alankar Dhobale]

Hi Max,

 

Yes you are right, I used the same bbappend and this resolved the issue, perfect solution…

 

I have been struggling with this since couple of days! 

 

Many thanks for your inputs and resolution.

 

I have tested the build for imx6ulevk as well as to our own machine, both worked well. Calibration passes correctly and also writes it to /etc/pointercal.xinput file and works perfect

 

Thanks once again…

 

Regards

Alankar

Does not installing xf86-input-libinput help? xinput-calibrator cannot cope with that input backend.

 

I used the following bbappend to achieve this:
