# To get that, compile it with STRIP= and maybe also that LV_CFLAGS - build_mpos.sh will do this by default already:

# python3 make.py "$target" LV_CFLAGS="-g -O0 -ggdb" STRIP= DISPLAY=sdl_display INDEV=sdl_pointer INDEV=sdl_keyboard "$manifest"

sudo sysctl -w kernel.core_pattern=/tmp/core.%p

# Now run it as usual (with run_desktop.sh)

# And when it crashes, the core will be dumped in /tmp/core.XXXXX

# Then analyse it with:

# gdb lvgl_micropython/build/lvgl_micropy_unix /tmp/core.185491

# For example, to see the stack trace of the error:
