If possible, copy the compilation log into a file and attach it here

@tore-espressif Should I set the target chip before make? Like this: TARGET=esp32 make? I've never cross this bug before.

[tore-espressif]

First line of your log says that you are using toolchain for esp32s2. It is only weird if you didn't set it yourself: esp32 should be default. Running idf.py set-target esp32 should fix the problem.

(Since ESP32S2 support was introduced in ESP-IDF 4.2, there is no alternative command for make, AFAIK)

[C47D]

Yep, it's weird because I've never used the esp32-s2 target. I will try your suggestion.

EDIT After running idf.py set-target esp32 I had to remove both sdkconfig and sdkconfig.old files and now I'm able to build with make, until reaching the build of the demo example

I was able to compile this project using make with the following patch https://github.com/lvgl/lvgl/pull/2108

[tore-espressif]

I was able to compile this project using make with the following patch lvgl/lvgl#2108

Yep, that was the last missing thing :)

[C47D]

Just saw it got merged, will update the lvgl submodule in a bit.
