No, it's not. The tl-wdr3600 has 8 MB flash, which -while not plenty- is sufficient for modern OpenWrt, now and within the immediate future. Your paste shows that you have a 3.9 MB large overlay at your disposal, but at the same time you already filled up 3.6 MB of that, leaving you with only 244 KB 'free' space. With jffs2 needing at least 5 free erase and you being down to 4 and under, that is a problem - you need to reset (firstboot) your device to recovery and keep a closer eye on your flash usage in the future. But your device is not one with systemic flash shortage, as 4 MB flash devices would be. 8 MB isn't much, it needs some attention to keep it at bay, but it is workable.

There must be something wrong with the sysupgrade image. I literally just did a firstboot reset and the device is full and not saving settings between reboots.

I have the same device, no issue here.

Try this builds.

Edimax 3G-6200n z OpenWrt 19.07.2 lost settings after reboot or turnoff. It doesn't create JFFS.

Steps:

  1. Download the latest version OpenWrt 19.07.2 to Edimax 3G-6200n.
  2. Set e.g. the password to the router and/or turn on the WiFi.
  3. Reboot the router with the reboot option in OpenWrt.
  4. The router has no settings previously saved - the status is as right after installing fresh OpenWRT - no password, no WiFi enabled, default settings.

Problem with JFFS.

Thanks for your feedback.
Can you determine which is the last working OpenWrt release that is working?

Yes, I can if it will be helpfull. I will find free time and check other versions of software for my Edimax.

@tmomas, I've checked many versions: 19.07.1, 19.07.0, 18.06.8, 18.06.7, 18.06.6, 18.06.0. In all these versions problem is as I wrote above.
Version 17.01.7 (lede-17.01.7-ramips-rt305x-3g-6200n-squashfs-sysupgrade.bin) works perfect and save settings after reboot.

Is it any chance to fix this?
I saved these logs from SSH console for all softs which I tested.
If you want more information tell me.

Unless you upgrade your flash to 8MB or more: No.
The easiest way to solve this problem: buy a device with sufficient resources (i.e. preferably 16MB flash) for current OpenWrt.

OK, I understand. This is not my main router but I was trying find where is problem and be sure that it's depends on software not hardware. So the problem is in hardware.
This device is very old so for me was suprise that I can flash 19.07.2, for example on newer TP-Link TL-MR3220 (v2) I can flash max 17.01.5. So I don't know why 19.07.2 exist for Edimax if it's not able to work on this hardware. :slight_smile:

I don't think the size is an issue for this device. However, the configuration gets lost after reboot.

I tried 19.07.6 and found the settings survived reboot. So this is a different issue I guess.

3 posts were split to a new topic: BThome hub 5A doesn't save settings

Do you also want to have devices reported here that experience OOM issues after an upgrade?

the following device has issues with 32MB RAM, according to the user first experienced with 19.07:

for me, finding devices tagged as being regularly supporting by 19.07 and then finding the same devices with OOM issues in forum threads seems a bit weird.

No, this thread is (was, with 21.02 these devices aren't built anyways) about devices with insufficient amounts of flash for the default firmware. 32 MB RAM is already documented explicitly and expected behaviour (it might still boot with reduced features, but that's another topic).

I see that for Edimax 3g-6200n we can check new version of OpenWrt and confirm that the problem still exist or is resolved:

Unfortunately my Edimax 6200n stopped working (in normal use). I will try to fix it or maybe get a new device. Or maybe someone can verify if the problem still exists on this Edimax model?

I checked on other Edimax 6200n equipment that I managed to get. Overall the same problem.

On 19.07.4 version I set the password and turned on WiFi, on the next higher versions and 19.07.3 I only set the password for the router. Settings are always lost after restarting the router with LuCI network. I updated the software without keeping the settings from the previous version. Logs are added in order of update. In the logs you can see e.g. differences in the amount of memory depending on the version (they are small). Below are logs for commands

mount
df -h
free

on individual versions of OpenWrt. I executed the commands after setting the password and rebooting.

Here, see that I go back to an older version from 19.07.9 to 19.07.3. Version 19.07.3 was not in firmware selector and I found the bin file with the firmware manually (https://downloads.openwrt.org/releases/17.01.3/targets/ramips/rt305x/).

As 19.07.x is EOL, there won't be any changes/ fixes anymore - not that there would be a fix to these size issues to begin with (other than disabling the affected devices from being built).

(Marking this thread as solved, as there is nothing to 'fix' anymore - 19.07.x is EOL, 21.02.x+ doesn't support 4 MB flash devices anyways, considering average firmware sizes just shy of 6 MB)
