i2s_driver_install casues Guru Meditation Error

[domosi]

I am new this whole thing....
I am trying to use a SPH0645 mic with a Lora32 board. The mic is not connected to the board yet.
When I try to install and RX i2s driver I always get an error.
Unfortunately I don't know how to interpret the error description (yet ) and I absolutely have no idea why is this not working

I really appreciate any help.

Here is my sample code.

Code: Select all

#include <stdlib.h>
#include <stddef.h>
#include <inttypes.h>
#include <string.h>
#include <stdio.h>
#include <stdbool.h>
#include <sys/time.h>

#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "freertos/event_groups.h"
#include "esp_system.h"
#include "esp_log.h"
#include "esp_system.h"
#include "driver/i2s.h"

#define TAG "main"

static void init_i2s()
{
	/* RX: I2S_NUM_1 */
	i2s_config_t i2s_config_rx = {
		mode: (i2s_mode_t)(I2S_MODE_MASTER | I2S_MODE_RX),
		sample_rate: 44100,
		bits_per_sample: I2S_BITS_PER_SAMPLE_32BIT,
		channel_format: I2S_CHANNEL_FMT_RIGHT_LEFT,
		communication_format: (i2s_comm_format_t)(I2S_COMM_FORMAT_I2S | I2S_COMM_FORMAT_I2S_MSB),
		intr_alloc_flags: ESP_INTR_FLAG_LEVEL1,
		dma_buf_count: 14,
		dma_buf_len: 64
	};

	printf("1.\r\n");

	i2s_pin_config_t pin_config_rx = {
		.bck_io_num = GPIO_NUM_17,
		.ws_io_num = GPIO_NUM_18,
		.data_out_num = I2S_PIN_NO_CHANGE,
		.data_in_num = GPIO_NUM_5
	};

	printf("2.\r\n");

	i2s_driver_install(I2S_NUM_1, &i2s_config_rx, 0, NULL);

	printf("3.\r\n");

	// i2s_set_pin(I2S_NUM_1, &pin_config_rx);
}

void example(void *pvParams)
{
	init_i2s();
}

void app_main()
{
    	printf("Hello world!\n");

    	xTaskCreatePinnedToCore(&example, "example", 16384, NULL, 20, NULL, 0);

}

The result is this:
------------------------------------------------------------------------------------------------------------
Hello world!

You get an IllegalInstruction exception, but your program counter seems to be normal... normally, one of the things that can cause this is if you somehow manage to de-configure one of the GPIOs the program flash is connected to, making the ESP32 unable to read its program code. I can't find any documentation about your board, but maybe you can try using different GPIOs?

In this there is no pins set (commented out).
But if I try to use the same the other direction, I mean not reading from a microphone, but writing to I2S ports, that is okay.
There is no error.

Maybe I contact the board producers.
