Run the samples/subsys/fs/fat_fs, the example of FAT file system usage with SDHC media get error

Question

Hi Nordic,

when I run the samples/subsys/fs/fat_fs, the example of FAT file system usage with SDHC media, get error as below:

I have no idea how to fix it.

the SD I am using is TOSHIBA C04G, the board I am using is nrf5340dk, and nrf connected SDK 1.7.0 used.

prj.conf is:

CONFIG_DISK_ACCESS=y
CONFIG_LOG=y
CONFIG_FILE_SYSTEM=y
CONFIG_FAT_FILESYSTEM_ELM=y
CONFIG_PRINTK=y
CONFIG_MAIN_STACK_SIZE=2048
CONFIG_SPI=y
CONFIG_DISK_DRIVER_SDMMC=y

and add the nrf5340dk_nrf5340_cpuapp.overlay file as below:

&spi2 {
    status = "okay";
    cs-gpios = <&gpio0 7 GPIO_ACTIVE_HIGH>;
    mosi-pin = <6>;
    sck-pin = <5>;
	miso-pin = <4>;

    sdhc0: sdhc@0 {
            compatible = "zephyr,mmc-spi-slot";
            reg = <0>;
            status = "okay";
            label = "SDHC0";
            spi-max-frequency = <24000000>;
    };
};
