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.

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 (256MB on GTA02) JFFS2-formatted file system

In U-Boot

See also bootloader.
GTA01Bv4 # printenv mtdparts
mtdparts=mtdparts=neo1973-nand:0x00040000(u-boot),0x00004000(u-boot_env),0x00200000(kernel),0x000a0000(splash),0x03d1c000(rootfs)

In Linux

root@fic-gta01:~$ cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00040000 00004000 "u-boot"
mtd1: 00004000 00004000 "u-boot_env"
mtd2: 00200000 00004000 "kernel"
mtd3: 000a0000 00004000 "splash"
mtd4: 03d1c000 00004000 "rootfs"

On my Freerunner (GTA02v5) the partitions look a bit different:

root@GTA02:~# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00200000 00010000 "physmap-flash.0"
mtd1: 00040000 00020000 "u-boot"
mtd2: 00040000 00020000 "u-boot_env"
mtd3: 00800000 00020000 "kernel"
mtd4: 000a0000 00020000 "splash"
mtd5: 00040000 00020000 "factory"
mtd6: 0f6a0000 00020000 "rootfs"
