Hello,

I am using a i.MX53 based SABRE tablet (SMD) board. 
The issue is, touch screen is not functional when I booted with Linux images from MMC card.

I have tried with 11.05_images and 11.05_source bundle (using ltib), but no luck.

I have exported below tslib env variables:

export TSLIB_CALIBFILE=/usr/etc/pointercal
export TSLIB_CONFFILE=/usr/etc/ts.conf
export TSLIB_PLUGINDIR=/usr/lib/ts
export TSLIB_FBDEVICE=/dev/fb0
export TSLIB_CONSOLEDEVICE=/dev/tty
export TSLIB_TSDEVICE=/dev/input/ts0

ts_print_raw giving all zeros.
Below is the output of ts_print_raw and dmesg log.
