I have an AMC7812EVM-PDK connected to the AMC7812EVM GUI using an SDM-USB-DIG. When JP1 is set to SPI on the EVM board everything works correctly, but, when I switch it to I2C, the GUI does not communicate with the EVM. I verified that there are no signals for SCL and SDA on the SDM-USB-DIG J3 connector. There are signals for MOSI MISO, SCLK, and CS.
