Just compiled like regular mpy, don't know how it is different in lvgl. This module runs as expected in build without lvgl.

Hi @TsXor !

It's a bit hard for me to say what is the problem by reading your code.
I don't know what you are trying to do, or how you configured / changed / built the project etc. If I could reproduce your problem on my side maybe I could help.

Please provide:

• Minimal, Reproducible Example for your problem. Please try to remove any line of code that is irrelevant to the problem.
• All the details for how you configure and build the project
• Step by step all the commands you run until your see this problem

The code I posted is almost reproducible. You just have to compile it as a dynamic module with a proper Makefile like any of the ones in examples/natmod/

Here is the full thing. Just clone this folder and run make inside it (you may need to compile mpy-cross first)

After building it, you just put it in the /lib folder and import it like:

from bisect import bisect_left

I can almost say that it is mp_obj_subscr that go wrong.
