Migration from version 7 to version 8 - Guru Meditation Error...

[SinglWolf]

I started migrating my project from LVGL version 7 to version 8. I commented out all the lines with compiler errors in order to make the firmware and then gradually put the project in order.
Display controller ILI9488.
And I ran into a problem where it shouldn't be in principle. My project in version 7 works fine. In the place where the problem arose, I did not make any changes, because in version 8 nothing has changed. Here is a code snippet from the project where the crash occurred:

// ..........................
	LOGO = lv_img_create(lv_scr_act());
#if defined(CONFIG_IDF_TARGET_ESP32S2)
	LV_IMG_DECLARE(RadiolaS2);
	lv_img_set_src(LOGO, &RadiolaS2);
#elif defined(CONFIG_IDF_TARGET_ESP32)
	LV_IMG_DECLARE(radiola2);
	lv_img_set_src(LOGO, &radiola2);
#endif
	lv_obj_align(LOGO, LV_ALIGN_CENTER, 0, 0);
#endif
	lv_refr_now(NULL); // <----- Here ESP32-C2 crash
// ..........................

The picture loads normally and crashes:

Why do I think it is crashing on lv_refr_now(NULL)?
I commented out all the lines with lv_refr_now(NULL) in the project and ESP32-S2 continued to work further exactly until the moment when the task to update the display content was triggered:

#if defined(CONFIG_IDF_TARGET_ESP32S2)
		if ((MainConfig->lcd_type != LCD_NONE))
		{
			if (xSemaphoreTake(xGuiSemaphore, portMAX_DELAY))
			{

				lv_task_handler(); // <------  main/services.c:1005
				xSemaphoreGive(xGuiSemaphore);
			}
		}
#endif

With an error like this:

Please help me figure out the problem.
Recently, all my messages have not been answered.
What is it? Conspiracy of silence?
So just let me know so.
Whereupon I'm leaving to look for another solution for displaying graphics for my project. And I will not waste my time on empty correspondence here.

[C47D]

I haven't tested using LVGLv8, I will get some ESP32S2 and C3 kits next week to try test the drivers.

From the first backtrace it seems to me that the disp->driver might be NULL, here

lvgl_esp32_drivers/lvgl_tft/disp_spi.c

Line 316 in f6999a5

lv_disp_flush_ready(disp->driver);

, can you validate it isn't NULL?

[SinglWolf]

I Inserted check lines into the function.

static void IRAM_ATTR spi_ready(spi_transaction_t *trans)
{
    disp_spi_send_flag_t flags = (disp_spi_send_flag_t)trans->user;

    if (flags & DISP_SPI_SIGNAL_FLUSH)
    {
        lv_disp_t *disp = NULL;

#if (LVGL_VERSION_MAJOR >= 7)
        disp = _lv_refr_get_disp_refreshing();
#else /* Before v7 */
        disp = lv_refr_get_disp_refreshing();
#endif

#if LVGL_VERSION_MAJOR < 8
        lv_disp_flush_ready(&disp->driver);
#else
        if (disp->driver == NULL) // <---- check
            printf("disp->driver == NULL\n"); // <---- check
        lv_disp_flush_ready(disp->driver); // <---- disp_spi.c:352
#endif
    }

    if (chained_post_cb)
    {
        chained_post_cb(trans);
    }
}

Didn't work even once.
If I understood Your question correctly, of course.

[SinglWolf]

I knew that the lv_disp_draw_buf_t structure in version 8 should be static, but I missed it.
I sprinkle ashes on my head.
