    Set I/O Voltage reads as 2.80V, SD_CLK Frequency is 649 KHz

    Please click "RIFF Box Pinout" button for RJ45 and VCC and VCCQ connection.
    This is not pinout from RIFF thus it's confusing.

    2.9v = VCC
    1.8v= VCCQ

    Note that for ISP connection You need to add 100 ohm pullup resistors between VCCQ and CMD and DAT0.
