I’m having problems doing project 2.1(Web Server-Control Outputs (ON/OFF Buttons)) from the Build Web Servers Book. After following all the instructions carefully, I uploaded everything to my ESP32 DOIT devkit v1 and it worked fine. Then I created a new project, but this time I changed the board to LOLIN D32. I copy pasted everything from the working sketch and pressed the upload button. This time however I started seeing SPIFFS mounting error messages in the serial monitor.
All the steps were done as per the book and I even tried pressing the erase flash button before uploading the filesystem image.
I had no problems with the previous tutorial and this LOLIN board so I’m not sure what to do.
The errors I get can be seen here: https://imgur.com/a/7ePaa7G
Can you show me which board exactly you have?
Can you share a link to your specific board?
