PCM1865EVM: PCM1865 EVM Mode2 4 ch usb stream

Part Number: PCM1865EVM
Other Parts Discussed in Thread: PCM1865

Hello,

Following instructions from : https://e2e.ti.com/support/data_converters/audio_converters/w/design_notes/2790.how-to-revive-a-usb-audio-evm

I was able to configure the USB-AudioEVM driver to support multiple sampling rates.

However, I wish to use the PCM1865 for it's 4 ch potential.

Is there a driver image that can be downloaded on the USB-I2X board which grants the PC access to 4 ch recordings?

I.E  is it possible to receive 4 ch data: ch1[L], ch1[R], ch2[L], ch2[R] through the USB-I2X?

Thank you

    Hello, Matias,

    Welcome to E2E, Thanks for your interest in our products!.

    Unfortunately, we only have firmware available for two channel operation. 

    Best Regards,

    Thank you Diego,

    For Mode2, does the PCM1865/PCM9211PT (Slave) provide two I2S outputs, for Ch1 & Ch2?

    Is the USB-I2X controller (master) limiting to 2 ch operation?

    May the PCM1865 (slave) be connected to a different master board, and route two I2S[L][R] from CH1[L][R] and CH2[L][R]?

    Thanks
