ft5x06 android 驱动,edt-ft5x06 driver issue

Hi,

I am trying to get edt-ft56x06 driver working with imx6sl.

I have added the driver in the Kernel and added dts entry. I have scoped the I2c, Reset and IRQ lines and all seems ok.

However, when I boot the system and touch the screen I get the following:

edt_ft5x06_ts_isr: 5 callbacks suppressed

edt_ft5x06 1-0038: Unexpected header: 000000!

edt_ft5x06 1-0038: Unexpected header: 000000!

Can anybody explain what could be wrong here?

Thanks.
