    There could be so many causes for problems, but all are logical to conclude:

    1. Some of the important connection points not connected (e.g. GND, VCC, VCCQ)
    2. Device provided with power, thus CPU took control over eMMC
    3. Wrongly configured VCCIO
    ...

    If You use RIFF1, which port You used to try these phones ? RJ45 or JTAG ? Do You have adapter board with external VCC/VCCQ, etc etc . . .

      1.Vccq 1.8 Use External Power Supply
      2.Vcc 2.8 to 3.3 use Riff box

      Try to Rj-45 Or JTAG

      Necessary need connect Riff box Gnd With Pcb ?

        VCCQ= VCCIO so better use the one from box (many users mix these)
        VCC is always 3.3 on RIFF box, is not variable.

        And of course, GND must be connected . . . My god
