8GB eMMC KMFN10012M-B214

1 - ID: ec de 94 f3 a4
1 - dump

page: 17920
block: 512p
sector: 64_1104_128_1104_64
XOR: 3DDA67, 512p

Page structure looks strange but it is real. There is 3x SA part, first 64 bytes, second 128 bytes in the middle of page and third at the end of the page - 64 bytes. Looks like the information about LBN is in all SA same. After apply XOR to DA part (XOR not clean) we can see text in dump.
Please create ECC, XOR and layout for it. Dump was read on other reader. Uploading dump and XOR for DA part (but it is just for test purposes).

Uploading.
I develop XOR for DA area, but have problem with XOR for ECC part, and with ECC. Probably it works after XOR. When will be ready I will let you know. I think it will be one solution for all four cases from my database:

The same structure and XOR is used also in other eMMC chips - for example in BGA280 eMCP KMR21000AM-A805 (oxec de 94 f3) which we got a case now so will be 4th case that laout will fit and can be solved Wink

Crossing finger

P.S
Summary of eMMC/eMCP with same XOR and structure:

KMFN10012M-B214 1x8GB
KMQN10006M-B318 1x8GB
KMQN1000SM-B316 1x8GB
KMQ310006A-B419 2x8GB
KMQ310013M-B316 2x8GB
KMR310001M-B611 2x8GB
KLM8G1GEND-B031 1x8GB
KMR21000AM-A805 4x8GB

if require reading 77, LBA, Photos (FAT32) from those let me know

77 and LBN pattern uploaded. XOR for data area also - XOR should be clean and ok.
Good luck!

Is it possible to make one more pattern?

Do you need buy new donor for it, or can use old?
