I2S sharing configuration

[MSyrota]

Hi,

I'm trying to configure shared I2S on the evkmimxrt685.
I'm looking into i2s_dma_record_playback sample and basically want to change the output interface - just get the data signal somewhere on the Arduino connector instead of routing it back to the evk codec.

So far I've tried reconfiguring the sample to use I2S2 and I2S4 interfaces (flexcomm2 and flexcomm4 respectively) and changing the FCx_RXD_SDA_MOSI_DATA pin in the pinmux tool, however it only disables the evk codec output and I don't have any signal on the Arduino pins.

I would appreciate any help with this.

Unfortunately, the Codec I2S output is not routed to any of the Arduino Pins. Only the input is also connected to J47[3].
I suggest you use the I2S sharing configuration so the codec output is internally connected to another Flexcomm that has board output.
For detailed information about this, I suggest you refer to chapter 4.6.2 from the User Manual.

If you have more questions do not hesitate to ask me.
Best regards,
Omar
