LVGL + ESP-IDF: Core 0 panic'ed (IllegalInstruction) by calling lv_timer_handler

[Mykyta_Mar]

Hardware used: ESP-32 S3 WROOM-1 (esp32-8048s070 board)

esp-idf version: 5.1

used projects:

1) https://github.com/espressif/esp-idf/tr ... /rgb_panel

2) https://github.com/MMlodzinski/Sunton_E ... GL_example

Hi, I'm trying to use one of these two projects for lvgl with esp-idf, but I'm getting the same error through both, namely it crashed when calling lv_timer_handler function. Does anyone have a solution to this problem?
