The Flash memory on the DS-101j is partitioned into 6 "/dev/mtd" devices:

The Flash memory on the DS-101 is partitioned into 8 "/dev/mtd" devices:

(:tableend:)

The Flash memory on the DS-101g+ is also partitioned into 8 "/dev/mtd" devices:

It's not clear (yet) why the DS-101g+ contains a Redboot FIS and configuration partition.

It's not clear (yet) why the DS-101g+ contains a Redboot FIS and configuration partition.

The Flash memory on the DS-101g+ is partitioned into 8 "/dev/mtd" devices:

It's not clear (yet) why the DS-101g+ contains a Redboot FIS and configuration partition.

The same layout is used for the DS-101g+, although partition sizes differ slightly.

The Flash memory on the DS-101 is partitioned into 8 "/dev/mtd" devices:

The same layout is used for the DS-101g+, altough partition sizes differ slightly.

The Flash memory is partitioned into 8 "/dev/mtd" devices:

1. /dev/mtd4 128k - vendor (Spelled "vender" in firmware)
2. /dev/mtd5 128k - synocfg
3. /dev/mtd6 128k - RedBoot Config partition
4. /dev/mtd7 128k - fisdir

1. /dev/mtd0 - 384k - RedBoot bootloader. This get executed when you first boot the ds101, and loads the kernel with the correct parameters.
2. /dev/mtd1 1536k - Kernel (Linux 2.4.22)
3. /dev/mtd2 7040k - initrd
4. /dev/mtd3 6912k - This is simply a tar.gz of the libraries used by the ds101. It is extracted to a newly formatted (internal) disk, and is restored from this partition if any of the files are missing. There also seems to be a "reinstall library flag" somewhere (Run strings updater|grep reinstall), so it should upgrade your libraries if you flash a new firmware.
5. /dev/mtd4 128k - Config-partition
6. /dev/mtd5 128k - Config-partition
7. /dev/mtd6 128k - Config-partition
8. /dev/mtd7 128k - Config-partition

I know one of mtd[4567] is the redboot config, and one is the SerComm signature. The two others I haven't figure out yet.

DS101 Flash partition map

1. /dev/mtd0 - RedBoot bootloader. This get executed when you first boot the ds101, and loads the kernel with the correct parameters.
2. /dev/mtd1 - Can't remember right now ;-)
3. /dev/mtd2 - Can't remember this either ;-)
4. /dev/mtd3 - This is simply a tar.gz of the libraries used by the ds101. It is extracted to a newly formatted (internal) disk, and is restored from this partition if any of the files are missing. There also seems to be a "reinstall library flag" somewhere (Run strings updater|grep reinstall), so it should upgrade your libraries if you flash a new firmware.
5. /dev/mtd4 - Can't remember this either ;-)
6. /dev/mtd5 - Can't remember this either ;-)
7. /dev/mtd6 - Can't remember this either ;-)
8. /dev/mtd7 - Can't remember this either ;-)

I know either mtd[567] is the redboot config. mtd1 and mtd2 are kernel and initrd, probably in that order.
