I'm developing a new board based on the IMX6q.
My configuration pins are as follows:
I can successfully request gpio3 and gpio6 for gpio output.
I can control gpio3 . But I can't control gpio6.And the ouput of gpio6 always is high.
When I measure the voltage of pin gpio6 is always 3.2V.
The software and hareware configuration of pin gpio3 and gpios is the same. Both they have a 4.7k pull-up resistor.
I have double checked my configuration.I am very confused.
Does anyone know what I am doing wrong? Any clue about that error?
