Using embedded port in ESP-IDF?

[NemesisXB]

I have been trying to use the embedded port using ESP-IDF but I am running into multiple issues which I have no idea how to solve.

I built the embedded port out-of-tree. the folder structure looks like this:

I successfully compile the embedded port. I then try to run the embedded example and it fails:
First it fails because of a redefinition of __assert_func: main/micropython_embed/port/embed_util.c:104: multiple definition of `__assert_func'; esp-idf/newlib/libnewlib.a(assert.c.obj):/opt/esp/idf/components/newlib/assert.c:34: first defined here
renaming the __assert_func in embed_util.c to __assert_func2 solves this issue. It then fails with this error: #error "Architecture not supported for gc_helper_get_regs. Set MICROPY_GCREGS_SETJMP to use the fallback implementation."
Adding MICROPY_GCREGS_SETJMP (1) to mpconfig.h, solves this issue.

It then compiles successfully, but fails on running with this stack trace:

Here is the code I am running:

/* This file is part of the MicroPython project, http://micropython.org/

 */

#include "port/micropython_embed.h"
#include <stdio.h>

// This is example 1 script, which will be compiled and executed.
static const char *example_1 =
    "print('hello world!', list(x + 1 for x in range(10)), end='eol\\n')";

// This is example 2 script, which will be compiled and executed.
static const char *example_2 =
    "for i in range(10):\n"
    "    print('iter {:08}'.format(i))\n"
    "\n"
    "try:\n"
    "    1//0\n"
    "except Exception as er:\n"
    "    print('caught exception', repr(er))\n"
    "\n"
    "import gc\n"
    "print('run GC collect')\n"
    "gc.collect()\n"
    "\n"
    "print('finish')\n"
    ;

// This array is the MicroPython GC heap.
static char heap[8 * 1024];

int app_main() {
    // Initialise MicroPython.
    //
    // Note: &stack_top below should be good enough for many cases.
    // However, depending on environment, there might be more appropriate
    // ways to get the stack top value.
    // eg. pthread_get_stackaddr_np, pthread_getattr_np,
    // __builtin_frame_address/__builtin_stack_address, etc.
    int stack_top;

    mp_embed_init(&heap[0], sizeof(heap), &stack_top);

    // Run the example scripts (they will be compiled first).
    mp_embed_exec_str(example_1);
    mp_embed_exec_str(example_2);

    // // Deinitialise MicroPython.
    mp_embed_deinit();

    return 0;
}

This is the mpconfigport.h file:

/* This file is part of the MicroPython project, http://micropython.org/
 * The MIT License (MIT)
 * Copyright (c) 2022-2023 Damien P. George
 */

// Include common MicroPython embed configuration.
#include <port/mpconfigport_common.h>

// Use the minimal starting configuration (disables all optional features).
#define MICROPY_CONFIG_ROM_LEVEL                (MICROPY_CONFIG_ROM_LEVEL_MINIMUM)

// MicroPython configuration.
#define MICROPY_ENABLE_COMPILER                 (1)
#define MICROPY_ENABLE_GC                       (1)
#define MICROPY_PY_GC                           (1)
#define MICROPY_GCREGS_SETJMP                   (1)

What am I missing?

On another note, is embedding the correct approach? We are building a product for a client for which they specified they want to be able to run python scripts (they specified micropython as a requirement).
