How to call a bound method object in a dynamic C module?

[TsXor]

mp_call_function_n_kw causes LoadProhibited
bound_meth_call is not available in dynruntime.h
mp_call_method_n_kw cannot compile: undefined symbol: mp_call_method_n_kw

note: lvgl version

This is the way to do it. You shouldn't care if the method is bound or not, you just call it like a regular method.

I suspect something is wrong with the method pointer or the way it's being created. Where does it come from -- is it passed to your code from Python or does the C code bind it?

My mistake, I allocated a struct on stack and passed its pointer somewhere else...
However, after I used m_malloc to allocate it on heap, it causes Interrupt wdt timeout on CPU0

My mistake again, I tried to modify the data of an object(obj_ptr->data) at C side.
