    Anyone test this pinout? I try this by RIFF and other box and not work by all.

    Open serial port...OK
    Connecting to the RIFF Box...OK
    Firmware Version: 1.54 (RIFFBOX1), JTAG Manager Version: 1.75

    Connecting to the SD/eMMC Card...ERROR
    Set I/O Voltage reads as 2.81V, SD_CLK Frequency is 2.50 MHz

    Connecting to the SD/eMMC Card Failed (ERR[0075], POS[000B])
