Guys any solution on corrupted /jffs/ on every reboot. Mine is Archer c9 v1 and is on the latest build.

DD-WRT v3.0-r47976 std (01/06/22)

Every time I reboot, files at /jffs/ are getting deleted.

Are you referring to jffs2, the use of your flash RAM as permanent storage or the use of an USB stick with jffs partition?

JFFS2 Support - Internal Flash Storage

It's working on my EA8500 for startup scripts. However on Archer C9, files are being deleted every reboot.

I split off your post.

Hijacking another thread is something which is frowned upon.

See the forum guidelines with helpful pointers about how to research your router, where and what firmware to download, where and how to post and many other helpful tips:

I never use JFFS2, the only time I bricked a router was when using it and upgrading.
Besides depending on setup you can wear out your flash ram.

So if possible just use an USB stick.

That said sometimes this is the only (viable) option to use permanent storage.

As the size of the firmware grows it is possible that it will overwrite the space for JFFS especially on routers with less than 64 MB flash RAM like yours.

So this might be a bug Sad

Gotcha, will try using USB and provide feedback.

Not sure if this commit applies to the bug:

https://svn.dd-wrt.com/changeset/48018

If this was split from a release thread, it wasn't necessary to do so. All bug reports and discussion should remain in the build threads.
