We have an issue that I would like to ask for your help with the iMX8M Plus.
We use pins GPIO4_IO and GPIO4_IO but do not succeed to change its value
(the pins does not response to the command).
I’m thinking that it could be related the Audio codec, SAI3, shared on the same pins
- SAI3_TXFS, GPIO4_IO
- SAI3_RXD, GPIO4_IO
Do you think that this could be the problem and if so what do we need to do to change the pin functionality?
