I am trying to understand the Flash Dump of a Meraki Z3. It uses the same Chip as the MR33 (s34ml01g2). I think i got all the chip data, but the Page Layout looks weird. Usually, the Chip should have a 2048kB + 64 Bytes Page separated into 512 Bytes Data and 16 Bytes Spare.
I seem to get 517 Bytes and 11 Bytes. At least for the uboot part. The rest adds up as well, but that does not make sense, and i am still missing 20 bytes spare per page.
Documentation:
Code: Select all
Page Size: 2kb
Block Size (without Spare): 128kB
Spare Area: 8 Byte/512 byte
OOB Size: 64 Bytes
BCH ECC: 4 Bit
There is a second Z3 in my possession, but i don't have a clip and had to desolder the chip, due to time constraints
