Hello! I tried to compile you code and ESP crashes with following results right after starting LVGL task:

LVGL port version is 2.4.1. Tried with IDF versions 5.3 and 5.4 and LVGL 9.2.0 and 9.2.2 with same results.

Any idea if the problem is with your code or LVGL port/LVGL?

[MMlodzinski]

@tommasoclini have you encountered such a problem during development?

[tommasoclini]

Considering the amount of issues related to lvgl port(https://github.com/espressif/esp-bsp/issues), I believe it's the new version that's causing the problem, my bad for not specifying the exact versions in the component manifest, I'm testing which version works now.

[tommasoclini]

It appears to be version 2.3.3 of esp_lvgl_port that introduced the bug, I'll create a pull request with the updated manifest.

[tommasoclini]

@rkoscikas can you try the fix? As of now it's in my fork's main branch.

[rkoscikas]

You guys are sure reacting quick, thank you. I will try your code as soon as I get home from work, but I was actually able to get the code working yesterday by using lv port 2.3.1, so I am sure your code will work fine. Tried number of different combinations, turns out that LVGL 8.4 works OK with lv port 2.4.1. With lv port 2.3.1 both LVGL 8.4 and 9.2.2 worked fine for me.

[tommasoclini]

Hit me up when you try 2.3.2 with both LVGL 8.4 and 9.2.2.

[rkoscikas]

Confirmed, 2.3.2 works correctly with both LVGL 8.4 and 9.2.2 . I guess this is closed? Thank you!

[tommasoclini]

@MMlodzinski can you merge my PR?

[MMlodzinski]

done

[tommasoclini]

thx
