Compiling RE450v1 snapshot: conf not saved after each reboot [Closed]


I compiled and sysupgraded the RE450v1 snapshot from git.

Something strange happened:

After flashing, modifications to /etc/conf/ are not saved (they seem to be saved when modifying in command line, but they are not saved to disc). After reboot, I am back to the original image like nothing was done. It seems that the filesystem is readonly.

Any idea?

Your image is too big and there's not enough space on the device to create a writeable overlay. So you can make changes to the running device but they'll be lost when you restart it.


Too bad ... I was planning to use it for mesh wireless.
I could test mesh and it is not working (again).

So, this is the end of my RE450v1 afaik
Devices with 8MB flash are really unsuitable for OpenWRT.

or you flashed initramfs image instead of sysupgrade one
how's the df -h says?

and if all else fails you can write config file to boot image itself while build
files in <buildroot dir>/files/ will inclued in built image
so config your image in filst boot - backup config files - insert it in new image

I am pretty sure I fashed the sysupgrade image. Here is the output of df -h:

df -h
Filesystem                Size      Used Available Use% Mounted on
/dev/root                 3.8M      3.8M         0 100% /rom
tmpfs                    60.3M     64.0K     60.2M   0% /tmp
tmpfs                    60.3M     60.0K     60.3M   0% /tmp/root
overlayfs:/tmp/root      60.3M     60.0K     60.3M   0% /
tmpfs                   512.0K         0    512.0K   0% /dev

On another device with 32 Flash, df -h returns:

df -h
Filesystem Size Used Available Use% Mounted on
/dev/root 3.0M 3.0M 0 100% /rom
tmpfs 122.5M 276.0K 122.3M 0% /tmp
/dev/mtdblock11 24.9M 3.3M 21.6M 13% /overlay
overlayfs:/overlay 24.9M 3.3M 21.6M 13% /
tmpfs 512.0K 0 512.0K 0% /dev
So there is clearly a problem.

You have to go really lean with your image, there's plenty of packages that can be removed if the device is just getting used as an AP.

I am really in favor of reusing old hardware in OpenWRT, to fight planned obsolescence. But in the case of the RE450v1, it does not seem to work in mesh mode, so it is not suitable to my needs. I will probably go for new hardware and buy a second GlibNet B1300.

Closing this issue. I just purchased a second GLiNet B1300.
