we have two RIoTboards in our test setups now, along with other imx6 boards, and they are working great! We are able to use SPI, I2C, UART and other connections. On other boards we now also acitivated the SPDIF input of the imx. Sadly, there is no pin available for this on the RIoT's expansion port.
The possible pins for SPDIF input are:
The question is now: How to access one these pins most comfortably?
Does anybody now if GPIO_16 is available on the bottom of the board, so we could solder a wire to it?
Does any of the other pins have an easily accessible contact spot?
