The internal flash memory is divided into partitions of several uses. The exact partition sizes are stored in the bootloader environment variable "mtdblocks", and depend on bad blocks of each device. Flashing openmoko updates partition contents.

GTA02 partitions different from GTA01 partitions, it comes with extra factory partition for productions. I guess this page is a duplicate and contents should be merged into the partitions page - OlivierBerger.


Neo1973 partitions
Name DFU# Linux mtd# Size Purpose
u-boot 1 0 256 kB Bootloader binary
u-boot_env 2 1 16 kB Checksummed bootloader config
kernel 3 2 2 MB Kernel uImage binary
splash 4 3 640 kB Bootloader splash screen
rootfs 5 4 rest of the 64 MB JFFS2-formatted file system

Via DFU
