ESP32 Forum

I am using Windows, VSCode and the ESP-IDF extention. I need to compile a project for several targets, for example ESP32, ESP32-C3 and ESP32-S3. I can do this manually by clicking the "ESP-IDF: Set Espressif Device Target" command, then "ESP-IDF: Build Project", then copying the binaries, and so on.
I need to do this programmatically, using a batch file.

I can compile by executing

idf.py app

in the terminal. But how can I change the target?

If I enter this:

idf.py set-target esp32c3

the terminal displays this:

Adding "set-target"'s dependency "fullclean" to list of commands with default set of options.
Executing action: fullclean
Executing action: set-target
Set Target to: esp32c3, new sdkconfig will be created.
Target 'esp32c3' specified on command line is not consistent with target 'esp32' in the environment.

This is not really supported well by IDF (same as sdkconfig for different scenarios, like, debug and release). You will find a lot of workarounds though. I‘m using a custom board directory for every single target where the sdkconfig resides in. The rest of the files is symlinked to the general directory.

See if un-setting the environment variable IDF_TARGET, or setting it to the desired target, before invoking idf.py set-target helps.
