mmc-spi error on STM32MP135-DK

[OPetr.2]

We are using STM32MP135-DK and we connect to SPI5 an SD Card Adapter.

We modified the device tree as follows to use the mmc-spi-slot driver:

&spi5{
    pinctrl-names = "default", "sleep";
    pinctrl-0 = <&spi5_pins_mx>;
    pinctrl-1 = <&spi5_sleep_pins_mx>;
    status = "okay";

    /* USER CODE BEGIN spi5 */
     spisdcard@0 {
        compatible = "mmc-spi-slot";
        reg = <0>;
        gpios = <&gpiog 1 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>;
        voltage-ranges = <3300 3300>;
        spi-max-frequency = <2400000>;
        status = "okay";
        disable-wp;
      };
    /* USER CODE END spi5 */
};

but we get this error on startup:

Could you help me to find what is wrong? We checked all the wiring and it is correct.

Hi @OPetr.2 ,

Can you please share the node spi5_pins_mx ?

Hi @Olivier GALLIEN,  the spi5_pins_mx node in device tree is as follow:

   spi5_pins_mx: spi5_mx-0 {
        pins {
            pinmux = <STM32_PINMUX('A', 8, AF5)>, /* SPI5_MISO */
<STM32_PINMUX('H', 3, AF5)>, /* SPI5_MOSI */
<STM32_PINMUX('H', 7, AF6)>, /* SPI5_SCK */
<STM32_PINMUX('H', 11, AF1)>; /* SPI5_NSS */
            bias-disable;
            drive-push-pull;
            slew-rate = <2>;
        };
    };
