Hi,
I tried with 11.05 build version, but not luck.
touch pad is not functioning.
The same thing added to a new discussion:
Please give me suggestions and let me know if I need to provide any further inputs.

Currently, I am using 11.03 version. I will start building 11.05 today.
Beside, I didn't fine the file called /usr/etc/pointercal in the existing 11.03 version.

I started using 11.05 kernel.
Also we need to kill the process ts_calibrate to actually go to the screen.
The calibrated values are
/usr/etc/pointercal

Hi Swamy,
I am facing the exact problem with the board i.MX53 SABRE SMD.
Booted with linux with Kernel version=2.6.35.3-998-ga1cd8a7.
Touch screen is not functioning.
Output of ts_print_raw command shows all 0's.
Did you get progress in this ?
Please suggest me on how to proceed on this.
Can you see any device like /dev/input/eventX?
Can you get any event on evtest?
