Hi NXP support,
OK, so if an th RT is driving its pin low it cannot really be detected as it is a direct short circuit.
If you configure this pin as a GPIO, in input mode, do you still have the issue?:
If I configure DISP_B2_01 as GPIO5_02 the level is correct on the lane !
That means the issue come from the SAI configuration.
There is this diagram in the SAI documentation.
TX_DATA2 is used for sai_rxdata2 if "obe" is 0 but there is no information about this "obe". My thought was that it is configured by register TCR4 on bits TCE "Transmit Channel Enable"
And as I posted TCR4 is 0x10010f3b so TCE is 0x1 (TX0 enable, other are disabled)
Any information about that ?
Hello @mike_susen ,
We don't actually have DAB feature implemented.
But I'll ask hardware guys to patch my board to get FM data on GPIO_DISP_B2_00.
I will also ask hardware guys to connect the microphone (currently GPIO_DISP_B2_06) on GPIO_DISP_B2_01.
