I am working with IMX53-QSB and ported Android ICS(4.0) and I have connected SEIKO MCIMX28LCD WVGA-REV-B LCD Touch screen, their are no issues with boot sequence and the GUI is also working properly. but the touch screen is not responding when i put my finger on the screen.
my bootargs are:
boot:> setenv bootargs_base 'console=ttymxc0,115200 init=/init androidboot.console=ttymxc0 pmem=128M fbmem=12M video=mxcfb0:dev=lcd,SEIKO-WVGA,if=RGB24,bpp=3 2 gpu_memory=128M vmalloc=576M no_console_suspend'
I am using 3.0.15 kernel.
in the make menuconfig > Device Drivers > Graphics support > SEIKO WVGA PANEL is enabled.
please suggest me, what has to be done to solve this problem.
Thanks and Regards
