wifi config not being saved using CLI and web frontend on Wemos D1 mini

[netweaver1970]

Hi, Im tryi'ng to configure my EBUSD Adapter v3 to connect my home WLAN. But every time, after entering SSID and password + Save/reboot in the web frontend, the Wemos D1 mini kind of hangs and only gets out of it by using the reset button, coming back with the default EBUS SSID. So my entered config is not saved.

Then I tried to do the same thing it via the CLI, over the serial port. I enter the same details, I can do a connect test there and it looks like I'm connected fine, I'm getting an IP address. So far so good. Then I chose '0' to save and reboot and alas, I'm getting again the EBUS SSID :( Same behaviour as using the web frontend.

And this is while saving and rebooting ... Back to square one.

I also tried to do an F: (Factory reset) and then setting the WIFI config parameters + save&robbot but I'm having the same behaviour.

I also tried restoring factory settings with 'f' : no luck, same behaviour.

I also tried the same with a powered hub in the middle, to rule out power issues: Same behaviour.

This is my EEPROM dump:

Any idea?

Some extra info, after doing the wifi config + connection, before doing the save+reboot, I now also do an EEPROM dump:

Contents looks different ... seems a lot gets overwritten/rewritten by a reboot ...

I just tried another long shot and this one worked : reflashed the binary. And as part of the (re)flash, it did a full flash wipe. Now the configuration is being saved properly. Closing the issue, keeping it here for reference.
