IMX6-GPIO CONFIGURATION

Question asked by li hu on Jul 30, 2018

Hi everyone,
 
I'm developing a new board based on the IMX6q.
My configuration pins are as follows:
MX6Q_PAD_GPIO_3__GPIO_1_3,
MX6Q_PAD_GPIO_6__GPIO_1_6,
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?
 
Kind regards
