Erase all Flash contents on sketch upload

Postby espforuandme » Tue Apr 27, 2021 7:27 pm

Hi,

since now i only used ESP8266.
When uploading a sketch via Arduino, you've got the options

Erase flash --> Only Sketch
Erase flash --> Sketch and WiFi Settings
Erase flash --> All flash contents (means also SPIFFS-Filesystem is cleaned)

When choosing ESP32 from Board-List this option is missing.
Is there something similar?

Primary i want the SPIFFS-Filesystem to be erased completely when uploading a new sketch (means a kind of "factory reset" of the ESP everytime i upload a new sketch.

Is this possible?

Best wishes
Daniel

Not sure if there is a more convenient way (maybe platformIO), but you could use:

Seems like this hasn't yet been addressed.

Any news from ESP devs on this?

Suggest you post it as an issue on the arduino-esp32 repo.
