Cannot build with latest framework-espidf @ 3.50100.0 (5.1.0)


I want to use the latest esp-idf release 3.50100.0 with platformio. However, I encounter issues. I already covered all options: fresh re-installed platformio including delete of .plarformio folder, updated packages, google, chatgpt, etc. However, error persists.

I see also a “not a git repository”. But that should not be the issue because previous version 3.50002.230601 is working without problems. I think is related to CMake Error kconfgen not able to create the sdkconfig.main file.
Any help is much appreciated.

My platformio.ini file:

default_envs = main

platform = espressif32@6.3.2                            ; see versions
board = esp32dev
framework = espidf
platform_packages = framework-espidf@3.50100.0   ; previous 3.50002.230601 is working, see versions
upload_speed = 921600
monitor_speed = 115200
monitor_raw = true

The output when I try to buid is:

I think this is what kills it, there’s a mismatch between what python packets the @6.3.2 platform installs and what python pacakges ESP-IDF 5.1.0 needs.

Currently, the references package vesion for the bleeding edge is 5.1.0.

So I’d recomment to just

  1. Delete C:\Users\EFeru\.platformio\penv\.espidf-5.1.0\
  2. Use the platformio.ini
default_envs = main

platform =
board = esp32dev
framework = espidf
upload_speed = 921600
monitor_speed = 115200
monitor_raw = true

Bingo! Works. Using platform = builds without issues.

Any reason why default platform = espressif32 gives issues and if it is planned to be fixed sometime soon?
Good to hear from you Max.

Well there isn’t really a problem, by using a specific platform version that’s meant to go with a specific (maximum( ESP-IDF version and using platform_packages to use a higher ESP-IDF version you’ve created a disconnect between the builder code and what package version it was meant to. The next stable package

The next stable platform version after 6.3.2 should have ESP-IDF 5.1.0 normally and you can reference that.
