Hi everyone,
I'm developing a new board based on the IMX6.

I have driven a touch screen on I2C bus 3.


Sometimes it's can work correctly.


Sometimes I get error as follows:

tsc2007 2-0048: dbg i2c io error: -5.

I found core cpu can't communicate with tsc2007,the touch screen chip.


Does anyone know what I am doing wrong? Any clue about that error?
Kind regards
