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 | JFFS2-formatted file system |
