Could anybody help with Technisat ZR EMMC pinout?
I have it connected like this:
Вложение FFF.jpg больше недоступно
Board DAT0 = Card reader pin 7
Board +3.3V = Card reader pin 4
Board GND = Card reader pin 3 and 6
Board CMD = Card reader pin 2
Board CLK = Card reader pin 5
I see the drive in Disk management, although it's marked as readonly.
When I start reading the drive with HDDRawCopy or EMMCRawToolkit, after few seconds I get this error (log from HDDRawCopy):

I tried to measure the +3.3V and GND, it's giving 3.3V. I tried several card readers, it's the same, although the first error I get is sooner or later. I tried to read the whole eMMC (4MB), it took about 40 minutes and I've got about 70 errors total.
I tried also connect the rest of the DAT1, 2, 3, but this didn't help - the result was the card reader was complaining that no card is in the reader.
I think something is wrong, but I can't figure out, what! Could anybody help please?
