Hi All
I am working on customized board based on AM3517evm.
I am using PSP 04.02.00.07, i have successfully modified the code of board-am3517evm.c and included driver for SX8652 in kernel.
During boot time my code gets stuck at calibration of touchscreen, as shown following, i am not able to understand a reason for this:
U-Boot 2010.06 (Apr 02 2012 - 12:13:51)

Calibrating touchscreen (first time only)xres = 1280, yres = 800
After this i tried changing the filesystem, i changed the filesystem to Angstrom built from narcissus-angstrom
now my code dose not hang.. when touchscreen is touched it gives "division by zero error" every time, and when i try to recalibrate it shows some junk values and dose not wait for the crosshair to be touched, what can be the reason for such a case?
following are the boot messages with angstrom filesystem
