Use UART for I2C

I’m trying to use the Hobbywing Xrotor FC with OmnibusF4SD target.
It looks like UART6 on this board can function as i2c bus if you remap the pins.
I’d like to know how to accomplish this remapping in PX4.


Unfortunately PX4 does not support dynamic pin configurations. It is fix assigned in the board and NuttX configs.
However the UART3 is configured as I2C on the Omnibus, have a look at
