SPI Devicetree error: undeclared here (not in a function)

[dhugoexe]

Hello,

I m' trying to setup a SPI communication between my board (rpi_pico) and an spi component (esp32_wroom32E). But I have some error that look like tihs:

C:/zephyrproject/app/build/zephyr/include/generated/zephyr/devicetree_generated.h:9907:47: error: 'DT_N_S_soc_S_spi_4003c000_S_esp32_wroom_32e_0_P_spi_max_frequency' undeclared here (not in a function); did you mean 'DT_N_S_soc_S_spi_4003c000_S_esp32_wroom_32e_0_P_reg_IDX_0_EXISTS'?

Here is my code:

#include <stdio.h>
#include <stdint.h>
#include <string.h>
#include <zephyr/kernel.h>
#include <zephyr/drivers/gpio.h>
#include <zephyr/drivers/spi.h>
#include <zephyr/drivers/gpio.h>
#include <zephyr/drivers/gpio.h>
#include <zephyr/logging/log.h>

#define SPI_OP      SPI_WORD_SET(8) | SPI_TRANSFER_MSB

#define START_CMD               0xE0

LOG_MODULE_REGISTER(main);

uint8_t fw_cmd[] = {START_CMD, GET_FW_VERSION_CMD, 0x00, END_CMD};

uint8_t rx_buf[BUFFER_SIZE] = {0};
    
struct spi_buf tx = {.buf = fw_cmd, .len = sizeof(fw_cmd)};
struct spi_buf rx = {.buf = rx_buf, .len = sizeof(rx_buf)};
struct spi_buf_set tx_set = {.buffers = &tx, .count = 1};
struct spi_buf_set rx_set = {.buffers = &rx, .count = 1};

const struct spi_dt_spec esp32_wifi_dev = SPI_DT_SPEC_GET(DT_NODELABEL(ouifi), SPI_OP, 0);

int main(void)
{
    int ret;

    if (!spi_is_ready_dt(&esp32_wifi_dev)) {
        LOG_ERR("SPI device not ready");
        return -1;
    }

    ret = spi_write_dt(&esp32_wifi_dev, &tx_set);
    LOG_INF("write return: %i\r\n", ret);

    if (ret == 0) {
        ret = spi_read_dt(&esp32_wifi_dev, &rx_set);
        LOG_INF("read return: %i\r\n", ret);
        
        if (ret == 0) {
            LOG_HEXDUMP_INF(rx_buf, sizeof(rx_buf), "Response:");
        }
    }

    return 0;
}

And my devicetree (overlay):

&spi0 {
        compatible = "raspberrypi,pico-spi";
        status = "okay";
        cs-gpios = <&gpio0 21 GPIO_ACTIVE_LOW>;
        pinctrl-0 = <&spi0_default>;
        pinctrl-names = "default";
        ouifi: esp32-wroom-32E@0 {
            compatible = "espressif,esp32_wroom_32e";
            status = "okay"; 
            reg = <0>;
            spi-max-frequency = <1600000>;
        };
    };

Thanks by advance for your help.
