    How to configure i2c pin 6 in a mini breakout board?


      Hi dev.

      I am working on a mini breakout board.


      My goal is to get data from two i2c devices.


      Touch sensor(QT1070) is works fine in i2c pin 1.


      Problem is an accelerometer(MMA8653FC) connected to i2c pin 6.


      I enabled the i2c pin 6 with the commands.

      # echo "mode1" > /sys/kernel/debug/gpio_debug/gpio27/current_pinmux

      # echo "mode1" > /sys/kernel/debug/gpio_debug/gpio28/current_pinmux

      i2cdetect result is



      I could not find anything.


      Is this means that the device is not connected? or my configuration is wrong?
