idf.py flash only, skip build

[MeriJo]

Hey,

I am setting up a pc for flashing my app onto many esp32-wroom-32e chips. I copied the project folder over and it flashed the app as it should.
I want to remove the base code (like main.c, etc) from the project because I don't want people using this pc to have access to it. But it seems that, when I run "idf.py -p comX flash" command, it tries to rebuild or it checks for those files and fails if I have them removed from the folder.

Is there a command to just flash the app onto the chip? Maybe use what's in the build folder?

Kind regards,
Meri

At the end of the output of "idf.py build" you can see the flashing command using esptool.py. Running that command won't re-trigger build.

This also means that you don't even need on the flashing machine to have ESP-IDF. You can set up just esptool.py there (https://docs.espressif.com/projects/esp ... ation.html) and copy over just the binaries to flash.

BTW, there is also a new "idf.py merge-bin" command (only in the very latest ESP-IDF) which creates one binary and then you can move to the flashing machine only one file.

Thank you so much!
