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:
