How should I set i.MX6 AUDMUX_PTCR and AUDMUX_PDCR.

[satoshishimoda]

Hi community,

I have a question about i.MX6 AUDMUX setting.

Please see the attached file, I want to know how should I set AUDMUX_PTCR and AUDMUX_PDCR with the use case.

I write the my guess setting value (PTCR & PDCR for port 2 and port 4) in the attached file also.

Is the setting correct?

If it is wrong, would you let me know what value should I modify?

Best Regards,

Hi Satoshi

I think settings are correct, except:

PTCR2:

RFSEL[20:17]=1011    (1xxx - select from RX port)

RCSEL[15:12=1011

PDCR4:

RXDSEL[15:13]=001

Best regards

igor

Hi Igor,

Thank you for checking.

And I found a mistake by my self.

I should set SYNC = 0b (async mode) if input RXC and RXFS from external device, shouldn't I?
