Please provide a complete description how to reproduce your problem:

• Your system configuration, distribution etc.
• ESP IDF version
• lv_micropython version you are using
• The exact and complete list of commands that brought you to this error.
• Any other information that is useful for someone else to reproduce this error.

[straga]

1. python:3.6-buster - docker
2. source /opt/upy/tools/esp-idf-v4.4.5/export.sh or esp-idf-v4.3.5
3. https://github.com/lvgl/lv_micropython/commit/3f25a765dafd5742639b85e94e845e370f73057f
4. make -C ports/esp32 LV_CFLAGS="-DLV_COLOR_DEPTH=16" BOARD=GENERIC_SPIRAM deploy
5. just run command from readme from lv_micropython

look like need remove . `return (user_data if user_data_found else None), get_user_data_accessors(containing_struct, containing_struct_name) `

to

a1, a2 = get_user_data_accessors(containing_struct, containing_struct_name)
return (user_data if user_data_found else None), a1, a2

also

def get_arg_name(arg):
    if isinstance(arg, c_ast.PtrDecl) or isinstance(arg, c_ast.FuncDecl):
        return get_arg_name(arg.type)
    if hasattr(arg, 'declname'): return arg.declname
    if hasattr(arg, 'name'): return name 
    return 'unnamed_arg'

if hasattr(arg, 'name'): return name -> if hasattr(arg, 'name'): return arg.name

Now firmware build. Need check flash real device esp32+ili9341+xpt2046 = work, but render very slow.

[amirgon]

esp32+ili9341+xpt2046 = work, but render very slow.

Do you use the generic driver or the ESP32 driver?

[straga]

ESP32 driver

from ili9XXX import ili9341

What is the frame rate you are seeing? (you can enable LV_USE_PERF_MONITOR to see frame rate) I've seen anything between 10FPS to 50FPS depending on the GUI complexity and the size of the area that is refreshed (LVGL tries to update only the areas that change between frames).
Also, you didn't specify what you tried to run. Does it happen with any LVGL example, or only with your code?

Today rebuild all. Erase all. Also I am experement with gc.threshold(2000) that was problem. Now works right. Thanks a lot for Help.
