[kainanzhu]

Hi NXP:

   I'm now porting audio. I used external  aux port is aux3 from Schematic, but I don't know which internal port is used.

   How do I ensure which internal aux port is used?

Thanks.

Hello

Like you said, according to the schematic, the external aux port is connected to aud3 port. But following the schematic that audio port is connected to the CSI0_DAT (4 - 7) of the i.MX6Q - DISP CSI. Confirming with the i.MX pins tool the CSI0_DAT (4 - 7) is muxed with the AUD3_TXC, AUD3_TXD, AUD3_TXFS, AUD3_RXD respectively.

I hope this can solve your question.

Best Regards,

Diego.
