spiffs.jpg

Looks better: Flash successful.
But:

Code: Select all    Dir dir = SPIFFS.openDir("/spiffs");
    Serial.println("Dateien im Verzeichnis:");   
    while (dir.next()) {
      Serial.println(dir.fileName());
    }

doesn't show any files....


@martinayotte:
You are sure, the offset = 0x6b000h???
512k-64k is IMHO 0x70000h. If I assume, that the SPIFF-area is at the end of the flash

- Mon Aug 10, 2015 1:48 pm #25560 Did you turn your ESP in UpLoad mode before trying to UpLoad your spiffstest.bin ?

On my side, the upload succeed, but when running the ESP, it like it has reformatted it to en empty SPIFFS.

- Mon Aug 10, 2015 1:53 pm #25562 With the NodeMCU tool, UploadMode is done automatically (like Arduino IDE) on my NodeMCU (ESP-12E)

Upload with Offset 0x70000h -> same result: empty directory

EDIT:
- Flashed a program on the ESP. Writing a file (Test.txt) into spiffs.
- Restart the ESP: "Test.txt" is available
- Flashing my spifftest.bin (with testspiffs.txt in it) with the NodeMCU-Tool at 0x70000h
- Restart the ESP: "Test.txt" still available.

Main question for me: how to know, what is the right offset???

Can you confirm this for a 512K Flash with 64K SPIFFS ?

Nope, you need to leave space for the Wifi settings.
Look at the board.txt for the different flavors of SPIFFS.

BTW, look at the other post, I've got some partial success, but still some issues.
