BMW MGU21 Emmc Writing Problem (Request) - donjuan020 - 01-06-2024
I detected MGU21 emmc pinouts with a multimeter. Now I can communicate and read. 128GB Toshiba Emmc available on it. But in the write function, the emmc write process does not start. Anyone have any ideas about the problem?I use UFI for these operations.

I just read and wrote about MGU18. No problem. However, this MGU21 can read, but I get an error while writing. Anyone have any ideas? Lastly, I will try to write by removing emmc.

you will succeed with removing EMMC, also, small hint, kilometer long cables will not work with your setup.

I can easily make MGU18 with this system, the cables are short. But I can write рдят5 5 and 6 on MGU21, рдятitions 7 and 8 always give errors. I use 1bit and clock 4 for processing.

MGU21(ID8) is only done by removing emmc.

Not true - at least not in my experience - yes the toshiba emmc is more difficult to get working perfectly but it is possible and works well when you have the "right formula".
RE: BMW MGU21 Emmc Writing Problem (Request) - RuleNormaliai - 04-06-2024
so without the "right formula" which you are the only one to have, it is only done by removing EMMC.
RE: BMW MGU21 Emmc Writing Problem (Request) - pshoey - 04-06-2024
no - Medusa Pro II plus resistors and the appropriate length wire works - just takes a little trial and error to get right.

even with cheap UFI it is possible without removing EMMC.
