WARNING: Toolchain version is not supported: esp32-2019r1 Expected to see version: esp-2019r2

Hello all,

I've just downloaded 'esp32_win32_msys2_environment_and_toolchain-20190611', installed msys32 and set the path in 'export_idf_path.sh' per the instructions at 'Standard Setup of Toolchain for Windows (Legacy GNU Make)'

I'm seeing this warning when compiling: "WARNING: Toolchain version is not supported: esp32-2019r1 Expected to see version: esp-2019r2".

Is there a newer toolchain than the one linked to? Do I need to be concerned about the warning?

Thanks in advance!

Hi ralphs,

Sorry, the new MSYS2 zip update is lagging the toolchain update. It will be updated before the final v4.0 release.

In the meantime, you can download the new toolchain from https://dl.espressif.com/dl/xtensa-esp3 ... -win32.zip and then delete the old toolchain (under C:\msys32\opt) and replace it with this one.

I am having the same issue.
I recently updated esp-idf master repo with git pull

Code: Select all

$ git describe --tags --dirty 
v4.1-dev-1572-g30372f5a4-dirty

/esp-idf$ ls

Where do I get the linux version esp-2019r2 of the toolchain?

Thanks.

For IDF v4.0 and later, we recommend using the new "ESP-IDF Tools" management system which is part of the master branch IDF version:
