Hi,
I'm using i.MX 6ULL for audio encoder product, Its need two SPDIF receive interface.
But i.MX only have one origin SPDIF receiver. I'm looking for ESAI to handle this.
as the ESAI document says:
The Enhanced Serial Audio Interface (ESAI) provides a full-duplex serial port for serial communication with a variety of serial devices, including industry-standard codecs, Sony/Phillips Digital Interface (SPDIF) transceivers, and other DSPs.
My question is: Does ESAI can working on SPDIF receiver mode and working together with i.MX's origin SPDIF(receiver), and any sample code for reference?
Hi xkwy
in general this is possibe, use spdif dts as examples :
spdif test description in
https://source.codeaurora.org/external/imx/imx-test/tree/test/mxc_spdif_test/doc?h=imx_5.4.47_2.2.0
and sect.7.5 Audio Mixer (AUDMIX) i.MX Linux Reference Manual
https://source.codeaurora.org/external/imx/imx-test/tree/test/mxc_amix_test?h=imx_5.4.47_2.2.0
Best regards

Hi, igorpadykov
Thanks for reply.
I have already know that the chip's SPDIF are working well just as you provide dts&doc links.
my question is that I need another SPDIF for my application(the chip only have one), can it reachable by ESAI?
Best Regards!
