determine available (unused) flash memory

[Timbopoise]

I've searched for an answer and reviewed espressif's documentation but no clear answer.  I'm sure I missed something.

when I run idf.py size I get an interesting table of information but the Flash usage is blank.

I'm on Ubuntu 24.04, VScode, ESP32-S3 8R8

Thanks

Something wrong with the software setup and installation. Better search for similar problem in ESP-IDF or VScode forums.

Maybe try Arduino IDE with these settings: https://github.com/OLIMEX/ESP32-S3-DevKit-LiPo/blob/main/SOFTWARE/Arduino/ESP32-S3-DevKit-Lipo-bat-sense/Arduino-Settings.jpg
