Hi All,
I am using customized am335x_sk , i have just initialized the touchscreen. But it throws me some errors. In my board setting the LCD display is in the daughter board. The distance between the baseboard and the daughter board is wider. Moreover the four wires length for the Touchscreen is unevenly arranged.
And my dmesg looks like this...
