Hi friends.I have strange situation with TNPH1116 motherboard . I can't connect via isp with emmc - KLM4G1FEAC .But I can read this board with emmc Toshiba - same connections , same programmers - Z3X and UFPI . I can't find good way to solve this problem . I have done it with internal and external supply .

Sorry, no experience in the emmc field.. only an advice, the lack of 1,8v supply by the programmer or by the board, the board need to enable them probably.. -
If you power the eMCC from the programmer, you got to make sure the crystal on the board is disabled. 2 clocks won't work. If the board is dead could be that the eMMC is dead or has bad BGA. There is a resistor on the data line like D0. Compare it to the resistors of the other data lines. If that resistor changes a bit of resistance, there will be no data transfer happening. Best to take the chip off and put it in an adapter.Comment
