Unfortunately the original ft5x_ts.c in linux-sunxi-sunxi-3.4.61 kernel doesn’t support A20, therefore, copy the new ft5x_ts.c [[http://dl.cubieboard.org/parteners/waveshare/Source_Code/A20/driver%20source/|ft5x_ts.c]] to the drivers/input/touchscreen directory in kernel and replace the original one. Besides, the touch screen interrupt pin ctp_int_port requires GPIO interrupts, make sure the GPIO driver is included when configuring. | + | Our capacitive touch screen integrates FT5206 as the touch controller, and the related driver file is ft5x_ts.c.
