I often will pop into a commandline to quickly tweek an ESP32 project instead of bringing up the Arduino IDE 2.x so I created a Makefile to compile some of my projects and because of the SPIFFS /LITTLEFS issue of the missing IDE 2.x GUI tool I added the capability to the Makefile. You will have to tweak you device port and some of the paths to where you put things but here's a semi-generic Makefile I copy to each of my ESP32 project directories. If on Windows you'll need to run it from a Linux container or something since I use make, grep, cat, cut, xargs, printf and maybe some other standard *nix tools to figure out flash filesystem settings based on chips used.
I compile using: make build
I compile and flash using: make build flash
I create my SPIFFS or LittleFS image using: make filesystem.bin
I upload my filesystem image using: make flash-fs
Code: Select all

# Usage: make build | flash | filesystem.bin | flash-fs | clean

. I think I rather suffer the need to put in the code for my OTA.
