I am trying to store text file into SPIFFS memory. I get an error whenever I try to format or to write file into SPIFFS.

Here is the code to format the SPIFFS.

#include<FS.h>


void setup() {
  Serial.begin(9600);
  SPIFFS.begin();
  delay(1000);
  Serial.println("Beggining format");
  if(SPIFFS.format()){
    Serial.println("Format complete");
  }
  else{
    Serial.println("unable to Format");
  }
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

I did search online in other forums regarding this error. I came accross this github discussion regarding the error. https://github.com/esp8266/Arduino/issues/4061 I did run the code suggested in this link to obtain the device ID.

Firmware: Chip Id: 000E01E5
Core version: 2_7_0
SDK version:2.2.2-dev(38a443e)
Boot version: 5
Boot mode: 1

Flash chip information: Flash chip Id: 00146085 (for example: Id=001640E0 Manuf=E0, Device=4016 (swap bytes))
Sketch thinks Flash RAM is size: 1.00 MB Actual size based on chip Id: 1.00 MB Flash frequency: 40.00 MHz
Flash write mode: DIO

File system (SPIFFS):
Total KB: 4176892.00 KB Used KB: 4176892.00 KB Block size: 8192
Page size: 256
Maximum open files: 5 Maximum path length: 32

SPIFFS directory {/} :

CPU frequency: 80 MHz

###############file open failed

In the output I see that: File system (SPIFFS): Total KB: 4176892.00 KB Used KB: 4176892.00 KB

I don't understand this. Can someone help me understand this? So that I can upload file to SPIFFS?

  • Try the following: In the dir of your sketch create a dir called data and place a *.txt file in it. Choose a 1- 2MB SPIFFS configuration fromTools ) e.g. SPIFFS/small App/ NO-OTA depending on your board Upload sketch and afterwards upload data with Tools->ESP8266 sketch data upload. If there is an error message post it in your edited question – Codebreaker007 May 07 '20 at 10:35
  • windows doesn't allow me to create *.txt in the data dir – Amrutha B V May 07 '20 at 13:33

  • Read [this](http://arduino.esp8266.com/Arduino/versions/2.0.0/doc/filesystem.html) first. You probably didn't setup/configure the SPIFFS correctly. What do you mean windows windows doesn't allow you to create *.txt file in data/ directory? Can you create a .txt on your desktop and copy it into the directory? What is the directory's permission setup? – hcheung May 07 '20 at 14:21
  • I mean to say i cannot name file with * , windows doesn't perrmit me to do that. I named file as example.txt – Amrutha B V May 07 '20 at 14:25
  • Yes *.txt means any text file so example.txt is ok - but from your system message you have noSPIFFS partition **FS:none** OTA:~502KB means NO FileSystem so create one Read the errormessageit says Only Sketch, 115200" SPIFFS Not Defined for Generic ESP8266 Module! – Codebreaker007 May 07 '20 at 16:57
  • Thanks!! I had selected wrong Flash type. File uploaded after I selected the right flash. Thanks for your support. – Amrutha B V May 07 '20 at 17:19
