Neo 1973 Partitions
From Openmoko
The internal flash memory is divided into partitions of several uses. The exact partition sizes are stored in the U-Boot environment variable "mtdblocks", and depend on bad blocks of each device. Flashing the Neo 1973 updates partition contents.
| Name | DFU# | Linux mtd# | Size | Purpose |

| u-boot_env | 2 | 1 | 16 kB | Checksummed U-Boot config |
| kernel | 3 | 2 | 2 MB | Kernel uImage binary |
| splash | 4 | 3 | 640 kB | U-Boot splash screen |
| rootfs | 5 | 4 | rest of the 64 MB (256MB on GTA02) | JFFS2-formatted file system |
