Crash after flash

[OperatorB]

Compilation was not turnkey process, anyways I face an issue after flashing. The core keeps panicing and bootlooping due to memory problem.

Below you can find some of the serial log:

I try to debug in the meantime however I am also open for suggestions.

There is an option to disable dual buffer in the config.

Not enough memory for LVGL buffer (buf2) allocation!

I will test again but not sure when.

I did a fresh git clone and now your demo works. The issue was that I changed esp_lvgl_port version from 2.0.0 to 2.2.2 inside idf_components.yml. But still a thing that was missing was the CONFIG_LV_USE_OBSERVER to be enabled via menuconfig. Please add this info to the readme. Thank you for your repo! I start building my hobby project.

If you do this (as per readme), observer should work fine

There is an issue where lvgl needs to fix it, so that it can be easier as discussed here https://github.com/espressif/esp-bsp/issues/318

and here https://github.com/lvgl/lvgl/issues/6010

[sukesh-ak]

I will upgrade to latest esp_lvgl_port and test next week. Meanwhile please read the README.md for the commands used to compile with all defaults set

# Build with "WT32-SC01 Plus" specific configuration
idf.py -D SDKCONFIG_DEFAULTS="sdkconfig.wt32sc01plus" build
idf.py -p <PORT> flash monitor

You are right, I forgot to untick the "Check this to not use custom lv_conf.h" inside menuconfig. Thanks for the issue tags. I have read the issues and I am not sure what would be the most elegant way. I agree that developers with the same hardware should have spend less time with config and more time with their project sw development. In the same time menuconfig is and will be a useful config tool which is frequently utilized with esp-idf platform.

Conclusion: If idf_components.yml in this repo still uses esp_lvgl_port v2.0.0 do not change it to newer version.

Will test with latest version when I get time next :)
