* cmd_ubi: add write.part command, to write a volume in multiple partsPaul Burton2013-10-09-0/+3
| | | | | | | | | | | | | | | | | | | | | | | This allows you to write data to an UBI volume when the amount of memory available to write that data from is less than the total size of the data. For example, you may split a root filesystem UBIFS image into parts, provide the total size of the image to the first write.part command and then use multiple write.part commands to write the subsequent parts of the volume. This results in a sequence of commands akin to: ext4load mmc 0:1 0x80000000 rootfs.ubifs.0 ubi write.part 0x80000000 root 0x08000000 0x18000000 ext4load mmc 0:1 0x80000000 rootfs.ubifs.1 ubi write.part 0x80000000 root 0x08000000 ext4load mmc 0:1 0x80000000 rootfs.ubifs.2 ubi write.part 0x80000000 root 0x08000000 This would write 384MiB of data to the UBI volume 'root' whilst only requiring 128MiB of said data to be held in memory at a time.
