[ts-7000] erasing (and recreating) rootfs partition in on-board flash

["odonovan_dan" <>]

Hi

I would like to completely erase the /dev/mtdblock/3 (rootfs)
partition on a TS7400 with 32MB flash, so that I can reinstall a clean
version of the ts-linux distro that comes pre-installed on it.

Can anyone suggest a suitable tool or technique to use for this?  I'm
hoping for something more low-level that 'rm -rf' if possible, perhaps
something that might scrub the OOB metadata produced by YAFFS also?

Also, if I use some tool to completely erase the contents of
/dev/mtdblock/3, would it then be sufficient to simply mount it as a
YAFFS partition again to recreate the filesystem or is there an
additional step that would be needed to "format" the partition?

Thanks,
-Dan
