i tried changing values in /sys/kernel/debug/gpio_debug/gpioXYZ/available_pullmode
and setting it to nopull
but either i'm not getting the right GPIO number corresponding to the pins labeled A4 and A5 on intel edison
or when i use lib mraa to communicate via I2c the pull up resistors are activated again.
how do you deactivate the pull up resistors ?
what are the correct gpio numbers for the pins corresponding to A4 A5 (based on documentation should have been either 19 and 20 or 27 and 28) i changed those with no luck.
asking this because my I2C sensor has also pull up resistors and i want to disable the edison internal ones.
this is from Intel's document:
