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?
