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.

Neo1973 partitions
Name DFU# Linux mtd# Size Purpose
u-boot 1 0 256 kB U-Boot binary
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

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_the_Neo_1973 updates partition contents.

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"
