Description

Cannot save anything on ESP12F. It seems that it fails to mount FS.

[tablatronix]

did you do a full flash erase?

[leofuscaldi]

I just found the problem... looking for my core version, I found that it was on 2.5.

I've downgraded it to 2.4 and it worked!

[tablatronix]

The memory might have changed you may need a full erase when switching versions

[leofuscaldi]

I've tried to full erase it, but made no diference. Only when I swiched back to 2.4 it worked.

[Albin76]

Hi. Same problem for me and also solved by downgrading esp8266 core from 2.5.0 to 2.4.0 thanks to @leofuscaldi comment! Thanks a lot @leofuscaldi, made my day! Have been troubleshooting for some time now. :)

[supriyono01]

Hi, I experienced the same thing. I have downgraded version 8266 from 2.5 to 2.4 but have not been able to solve the problem. Can help me.... After I tried it many times it turned out that it was saved but provided that when I left the portal, it was directly connected to the ap. If it is not directly connected then the parameters that we enter through the portal cannot be saved

[tablatronix]

have you guys tried a basic spiffs example, NOT wm?

[tablatronix]

2.5 release notes say that build flags changed and is a breaking change, are your arduino IDEs up to date, maybe spiffs is now disabled

[supriyono01]

Ok...thankyou, I will try to update my arduino ide.

Having issues with this as well. Downgrading to 2.4.x (all versions) breaks my MQTT/pubsub client as well. So, I can either have functioning FS or functioning MQTT... But I can't figure out what the changes are. ESP12F, core versions 2.4.x and 2.5.2. WifiManager development branch.

[tablatronix]

Hmm which default arduino examples have you tried ? i will test them

[DanwithArduino]

Might not be WiFiManager's problem. I just tried https://github.com/bblanchon/ArduinoJson/blob/6.x/examples/JsonConfigFile/JsonConfigFile.ino and am still unable to mount the file system.

[tablatronix]

That is for SD cards is it not?

[DanwithArduino]

Found the solution: In the Arduino IDE (or presumably the board manager in VScode but have not verified - should be same functionality) go to tools\Flash Size\choose one.... So far, I am getting positive results for 4M (1M SPIFFS).

[tablatronix]

Yeah that is typically the setting you use for spiffs, unless we are having a memory issue here? Development is surely larger that release, but I made sure it was not that much

[DanwithArduino]

I had 4M (No Spiffs) before. Still learnding. Thanks for the replies. I think I'm all good now after a few days of head banging.

[carlesgutierrez]

Hello, I'm not able to write or read using SPIFFS. I've succesfully checked before that SPIFFS works on a regular example without the wifiManager. How I can check if It FAILS to mount FS?

My configuration:

• nodemcu v2 / v3
• ESP Core Version: 2.4 or 2.5

[tablatronix]

do you have spiffs enabled, I think it is now optional not default.

[carlesgutierrez]

Hey, If do you mean by enable: mode to Flash Size to "4M (1M SPIFFS)", yes I did

[tablatronix]

if (SPIFFS.begin()) should do that.

hmm Have you tried full erase?

[carlesgutierrez]

You are absolutelly right. I had forgotten to setup SPIFFS with SPIFFS.begin() Thanks!!

[tablatronix]

might also want to close spiffs after using it

[carlesgutierrez]

Thanks for the advise @tablatronix , I will.

[cunhaeduardo]

Hi guys! Today I have the same problem as you and I solved it changing configuration in tool -> flash size -> 4M(1M SPIFFS). Someone posted it but I'm doing it again to be easier to find!

[Zadkiel2]

Hi guys! Please help me with the project I am building now. The project needs codes like this but I had problems dealing with ArduinoJson 6 and I am really new to these kind of things so I really have no idea about it. Hope you guys help me out. Salamat.
