|

- Flash type : SD
- Brand : Lexar 2000x
- Totall size: 128Gb
- ID: 2c c4 08 32
- Banks: 6
- Channel: 1
- Page: 18592
- Structure: 16*(1024_126)/31
- Sector: 1150
- XOR: D7AF/2850
- Layouts fits for ECC and gives FAT tables and MBR:
SM2702 1150_31 Xor 2850
SM2702 1150_31 Xor 2850_1024
SM3257 1150_27 Xor 2850_128 BP-2048
SM3257 1150_27 Xor 2850_256
SM3257_41 1150_27 Xor 2850_384_256
NOTES 2449:
1) There are totall 6 crystals and each is 64Gb giving over 400Gb of data while real size of card is 128Gb (?1?!) - I know location of additional 2 crystals but they are not answering... no metter if we use NR or manual CE pull down
2) I see FAT tables, MBR parts at 0x40ffd4200 (01_02 ) and 0x16c800000 (01_04) but whetever combination I use I cannot get correct mix
Need your help

Dump repeats after each 0x480000000 with layout -> 0x51B400000 in raw dump -> 18 GB
2c c4 08 32 - is original chip ID?

Yes - this is original ID
This explain why it's marked 128GB..... 8 CE x 18Gb = 144 GB with SA and ECC. So looks like Lexar make those cards (128Gb/256Gb/400Gb) with same NAND capacity and ID and just increase by internal firmware card capacity
We got only 6 CE here - two are dead so real 6 x 18Gb = 108 Gb.... any luck with mix find ?
