Intel Skylake I2S Routing

Hi,

I am using intel development board with skylake.

Now I2S1(SSP0) is configured and can playback and record audio via this.

aplay -l listing only this I2S.

I want to use another I2S(i2s2) for recording and i2s1 for playback.

Is it possible to route the I2S2 from userspace? Could anybody suggest how can I do this?

Regards

vjs

Hi,

Thank you for the reply.

I am using the custom design. Now I2S-1 is supported in BSP and I could able to playback it.

Now I want to use the second I2S-2. Please let me know which all places need to be modified.

I think the I2S routing is done in FW binary(dfw_sst.bin) file. Is it possible to support the I2S-2 without the FW binary change?

Regards
