SM-C101 Can't init device, Reason: OCR Ready Timeout Error - GSM-Forum

hondavtec · 09-10-2019, 16:25

Hi guys,

I'm new to this... got an Easy JTAG Plus Box and carefully connected the pins from board to interface but can't get any reply from board... I have a total of three C101 boards:

one dead, one boots and one I already took the chip off.
I do not have much hope to get the data off the dead one, but for now I would be happy to get at least one of those boards to present me ANY data

Can anybody please tell me which settings I have to make for this board?

BTW: already connected pullup resistors... would like to upload pics, but I'm not allowed

If eMMC is dead, what you want? ISP for eMMC is restored by magic?

No, only one ist probably dead but I want to at least try to get data, my problem ist that I can't even manage to connect to the good ones...

ISP connection works fine when using "HiPower CLK" mode (connect only CMD/CLK/D0/GND) set HiPower mode at software and power up PCB from USB (charger)

In cases where power is supplied from the box to the board, the voltages that come from the box is power up the processor and other parts of the board, and this is interfering with the work with eMMC

Therefore, we can’t guarantee excellent ISP connection works with different boards, only through the "HiPower CLK" mode

Thank you VERY much for this information!
Very helpful!
