ESP8266 doesn't save Wifi settings

I will publish a correction for esp8266 also.

It could be also that you selected a wrong flash size when uploading.

Some info about this:

E (588) SPIFFS: mount failed, -10025

Type: For reference Resolution: Awaiting response

Even the simplest ```cpp #include "Arduino.h" #include "FS.h" #include "SPIF…FS.h" void setup() { SPIFFS.begin(); } void loop() { } ``` crashes with an error ``` E (588) SPIFFS: mount failed, -10025 [E][SPIFFS.cpp:47] begin(): Mounting SPIFFS failed! Error: -1 ``` It used to work for a while on the same board when there was only an unoffical SPIFFS available, but today even the unofficial one has crashed. Is it a problem with the board? I have the newest version from the repository. I have saved a few files containing a few chars earlier.

SPIFFS.begin() crashes (stops) ESP without errors and only a line of garbage in serial monitor

### Basic Infos #### Hardware Hardware: ESP-07 Core version: I don't know… ### Description All I get in the serial monitor is this: > rrlaz|ela|Œlìb|Ž‚ì’r’bŒbŒònnžlnnœâìbpŒŽlrlrl‚rò’nàbânbp When I should get (if ESP not damaged): > OKOK? Or if damaged I should get an error message or equivalent that SPIFFS begin fails. If I remove "SPIFFS.begin();" The sketch runs normally. ### Settings in IDE Module: Generic ESP8266 Module Flash Size: 4MB CPU Frequency: 80Mhz Flash Mode: dio Flash Frequency: 40Mhz Upload Using: SERIAL Reset Method: ck ### Sketch ```` #include "FS.h" void setup() { Serial.begin(115200); Serial.println("OKOK?"); SPIFFS.begin(); } void loop() { } ````
