Change pin configuration during runtime

[roman_g1]

Hi,

i need to reconfigure my I2C clock and data line to GPIO during runtime.

How is it possible on imx8-m4?

Thanks

Unfortunately runtime pin configuration is not supported by the BSP.
However you can try to write to IOMUX registers directly from application.

Ok, thank you for your reply.

Is there a given sequence to write to register for changing the pin configuration?

For example if i want to write to MIPI_DSI1_GPIO0_00 register to set the mode to "000b".

Is the mux_mode field to set enough?
