Want to compile for ESP32S3 not ESP32

[olivertrepte]

I have a Waveshare ESP32S3 A7670E board and am trying to get hello_world from the ESP-IDF to work. I can compile but when trying to flash, it tells me

A fatal error occurred: This chip is ESP32-S3 not ESP32. Wrong --chip argument?

I am at a loss to understand where I should configure the environment for ESP32-S3. Probably just a simple setting, but I am not able to find it. Help appreciated.

Pretty simple indeed. Just do `idf.py set-target esp32s2`.

Thanks! I have tried it but get:

>idf.py set-target esp32s3
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: esp32s3, new sdkconfig will be created.
Target 'esp32s3' specified on command line is not consistent with target 'esp32' in the environment.

When I then try to compile and flash, the problem remains. Is there anywhere else I need to change the target?

[ESP_Sprite]

Not sure. Are you using vscode or something? If so, you may need to change it in the IDE.

[olivertrepte]

Yes, I am using VS Code, but I can't find where to change the environment target setting there. Any ideas?

[ESP_Sprite]

I think it's one of the buttons on the bottom bar, but I don't use vscode myself, so I don't know for sure.

I got it to work by running "New project" in the Welcome to Espressif IDF extensions graphical interface rather than following the command line procedure outlined by Espressif. Thanks for assistance!

you can try
export IDF_TARGET=esp32s3
# then
idf.py set-target esp32s3

for my case, i'm using idf terminal in vscode, the solution is simply open a new terminal after set-target, probably there is a bug that the terminal failed to refresh it's env even though we set the target successfully

To avoid the hassle, I include this into my projects' CMakeLists.txt:

Code: Select all

if(NOT DEFINED ENV{IDF_TARGET})
    set(ENV{IDF_TARGET} esp32s3)
    message("IDF_TARGET not set, defaulting to: $ENV{IDF_TARGET}")
endif()
