Settings changes are not persisted in electrodragon #252

Steps:

Flashed Electrodragon relay board r1.6 with blank 1Mb image
Flashed it with espurna v 1.9.5
Connected to board from laptop
Change password, set Hostname and Wifi
Clicked Reconnect in UI (without disconnecting power)
Module was able to connect to my wifi. I logged and checked its hostname. So far my changes are preserved
Now disconnect and connect power. I expect that module will connect to wifi once again, but nothing. If i scan wifi then i see that module started as AP again. Well, try to login with the new password - doesn't work. Use default fibonacci password and see initialization flow (set password).

I also tried to configure MQTT without disconnecting power. MQTT and relays work well. So looks like problem not in hardware. I use espurna with 2 sonoff basic and slampher and had no such issue.

Can you advise what how i can help with debugging issue?

Check that you have flashed it with the correct memory size. If you have flashed it with a 4Mb memory layout, since the Basic only has 1Mb it will not be able to persist the configuration. It will work as long as it is plugged, but once rebooted settings will have gone away...

Same here with an "Sonoff Basic". Settings get lost when the sonoff looses power

I use nodemcu-flasher with parameters:

Flash size = 1MByte
Flash speed = 40Mhz
SPI mode = DOUT

As blank i use 0x00000 blank1m.bin from https://wifi-iot.com/?m=main&download=3

image for electrodragon that expects a 4Mb "filesystem"

Ouch, i didn't realize that it has 4Mb. All my other sonoff devices have 1Mb. Let me try to reproduce it tonight.

Sorry, I have not been able to reproduce it. My Electrodragon board was flashed with ESPurna 1.2.0, upgraded to 1.9.5 and changed some settings, unplugged it and plugged it again and the changes where there... I understand your board was virgin, without any other firmware, when you flashed the blank 1Mb image. What is that? Then you flashed ESPurna image for electrodragon that expects a 4Mb "filesystem", that could be the problem. How did you flash ESPurna?

Just tested with Sonoff-Tasmota, works as expected. So need to figure out why it doesn't save settings. Also forgot to say that i used precompiled espurna-1.9.5-electrodragon-wifi-iot.bin.
