Details

The config partition is either the yaffs2 /var/flash TFFS-Configuration partition or an unused UBI volume.

On CONFIG_CONFIGSPACE_ONNAND models this is mounted to /var/flash using yaffs2:

7490 fw 7.29:

fritz3:/var/mod/root $ mount | grep flash

/dev/mtdblock4 on /var/flash type yaffs2 (rw,sync,relatime)

On some CONFIG_UBI models this is the unused avm_config volume.
It gets a device and is renamed before it gets an entry in /proc/mtd but it's empty (0xFF):

7530 fw 7.39:

root@fritz:/var/mod/root# ubinfo -d 0 -N 'avm_config'

Volume ID:   2 (on ubi0)
Type:        dynamic

This was maybe an experiment to use ubifs for the TFFS-Configuration but this would require recoveries to create
empty ubifs images, and it would require complete UBI and ubifs drivers in EVA to repair the TFFS-Configuration.
However, this was never used in favor of the nand-tffs partition.

Dependencies

Daily updated index of all dependencies of this partition. Last update: GMT.
A * in the Mod column marks info from Supportdata-Probes, which will always stay incomplete.
A ** in the Mod column marks info from Supportdata2 probes, which by their nature will stay way more incomplete.
A - in the Mod column marks manual research, the Firmware then shows where the item occurs, not the Relation.

Model-Matrix

Daily updated index of the presence, path and size of this partition for each model. Last update: 2024-03-28 06:52 GMT.
Showing all models using this partition. Click any column header (click-wait-click) to sort the list by the respective data.
The (main/scrpn/boot/arm/prx/atom) label in the Model column shows which CPU is meant for models with multiple Linux instances.
Note that this list comes from Supportdata-Probes, which can have arbitrary settings and come from different firmware versions.
It doesn't say much if a model is not listed here. It may be a missing supportdata file or just a disabled feature.

Missing Supportdata

The data in this article is incomplete due to missing Supportdata-Probes for the models listed below.
If you own any of these models and would like to help then please get in touch.
