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

OpenEmbedded/bitbake

  1. [bitbake task list]

Backing up data stored on the factory Neo

Things that needs to be backed up.

  1. 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
