My notes
Backing up data stored on the factory Neo
Things that needs to be backed up.
- GPS software (no need to back it up see: [GPS driver (gllin) licensing question])
- Factory-programmed NAND bad block information?
Initial Backup
Describes the backup of the 4 partitions, but does this include the factory bad block table? I think NOT
NAND_bad_blocks contains some information on the bad block information stored in the flash
Bad block notes
According to NAND_basics each flash page (512 bytes) has 16 bytes of out-of-band (OOB) data. The OOB contains different information but among other things it can mark a page? as bad.
According to Bad Block Table (BBT)
there is also a Bad Block Table that contains additional information.
Is this the same as the factory-programmed NAND bad block information discussed in Neo1973_Hardware?
Recreating the Factory-programmed NAND bad block information
Can the method described in BBT Creation does it (sort of) recreate the Factory-programmed NAND bad block information
NOTE: this method probably requires a JTAG cable
