IRAM is almost overflow. Is it okay ?

idf.py size command console return :

My thread function does not work right and I see my micropython allocate to CPU1 when I push reset button.

Could someone help me?

Does your thread function use the @micropython.native decorator? At runtime that's the only thing that uses IRAM.

If you want to reduce IRAM usage in your compiled firmware, see the MICROPY_WRAP_MP_ macros in ports/esp32/mpconfigport.h. If you comment out any of these then those corresponding functions will be placed in ROM instead.

Hi jimmo, could you give me some more details?
When I comment out to place MICROPY_WRAP_MP_ macros in ROM and to build it by idf.py build command , I got a lots of issues on console and it does not built.
What do you mean "thread function"? I use built-in thread, it is import _thread

from libs import WavP
import _thread
from time import sleep_ms

Plyr = WavP.WavP()

_thread.start_new_thread(Plyr.play_wav,("wav_files/at.wav",))

sleep_ms(500)

Plyr.status = 0

This works for me

#define MICROPY_WRAP_MP_BINARY_OP(f) IRAM_ATTR f
#define MICROPY_WRAP_MP_EXECUTE_BYTECODE(f) IRAM_ATTR f
#define MICROPY_WRAP_MP_LOAD_GLOBAL(f) IRAM_ATTR f
#define MICROPY_WRAP_MP_LOAD_NAME(f) IRAM_ATTR f
#define MICROPY_WRAP_MP_MAP_LOOKUP(f) IRAM_ATTR f
// #define MICROPY_WRAP_MP_OBJ_GET_TYPE(f) IRAM_ATTR f
// #define MICROPY_WRAP_MP_SCHED_EXCEPTION(f) IRAM_ATTR f
// #define MICROPY_WRAP_MP_SCHED_KEYBOARD_INTERRUPT(f) IRAM_ATTR f

What do you mean "thread function"? I use built-in thread, it is import _thread

You said "My thread function does not work right" in the original post, so I was asking what you meant by that.

What is WavP? Does it use @micropython.native ?
