My notes

Private index of useful pages

  1. [Application_Development_Crash_Course]
  2. [MokoMakefile]

Interesting paths

  1. moko/openembedded contains the bb files for 2007.2
  2. moko/openmoko/trunk/src/target/OM-2007.2/ contains the src files for the OpenMoko 2007.2 apps

Backing up data stored on the factory Neo

Things that needs to be backed up.

  1. GPS software (no need to back it up see: [GPS driver (gllin) licensing question])
  2. 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
