SPIFFS.begin() fails on Lolin d1 mini V3.1.0

[pluypen]

Hi,

I'm new here and just bought some Lolin d1 mini's V3.1.0, wanting to connect a ws2812b as an ambilight for my monitor.

When trying to get it all to work, I ran into trouble getting my d1 mini connected to the wifi. Here is what i did:

1. Downloaded diyhue/lights
2. Opened Generic_WS2812_Strip.ino in Arduino IDE
3. Adjusted lightscount to 10
4. Adjusted pixelcount to 80
5. Adjusted transitionleds to 2 Saved the script
6. Compiled the script
7. uploaded the script using Arduine IDE
8. Tried searching for wifinetwork: Hue rgb strip. I couldn't find the network or anything remotely close
9. Went back to Arduino IDE and looked for: void setup()
10. Uncommented: Serial.begin(115200);
11. Uncommented: Serial.println("Failed to mount file system");
12. started serial monitor
13. Saved, compiled and uploaded the script again
14. Got the message in serial monitor: Failed to mount file system
15. Went back to Arduino IDE and commented: // if (!SPIFFS.begin()) { //// Serial.println("Failed to mount file system"); // return; // }
16. Saved, compiled and uploaded the script again
17. Tried searching for wifinetwork: Hue rgb strip
18. Found the network this time
19. configured the network, went to the ip adress I got from the serial monitor
20. Could control the lights. But they are slow to respond.
21. Trying to change the transitionleds via the ui, crashed the d1 mini

Have I missed some steps causing SPIFFS.begin() to fail?

Please avoid any beta library and erase ell flash on first write.

Have you compiled the script with spiffs enabled? otherwise no memory will be reserved and SPIFFS.begin() will fail.

Yes! Enabling SPIFFS did the trick. After setting it to 1M SPIFFS, the script ran without issue. I can now change settings via the UI too. Thank you so much for your comments
