Hi community,

I havea a question about AUDMUX setting.

I understand the setting when not swapping TX and RX in How should I set i.MX6 AUDMUX_PTCR and AUDMUX_PDCR. .

Then, how about in the case of the attached file?

Best Regards,

Satoshi Shimoda

Hi Satoshi

connections in attached file are quite ambiguous as in

I.MX6 connection AUDMUX port 7 with SSI3 is internally fixed and

usual connection (device_TXD -> AUD_TXD, AUD_RXD->device_RXD)

does not require TXRXEN switch set.

Best regards

igor
