Hey guys, I’m still having issues trying to log temperature data from the MCP9808 sensor to an SD card using an ATmega2560 and Zephyr OS, how can I resolve the SD card initialization error? Despite setting up the SD card interface and implementing file write operations, I still encountered the error “Failed to mount SD card.” Here’s the code:

#include <zephyr.h>
#include <fs/fs.h>
#include <ff.h>
#include <logging/log.h>

LOG_MODULE_REGISTER(main);

void main(void)
{
    static FATFS fat_fs;
    struct fs_mount_t mp = {
        .type = FS_FATFS,
        .fs_data = &fat_fs,
    };

    if (fs_mount(&mp) != 0) {
        LOG_ERR("Failed to mount SD card");
        return;
    }

    struct fs_file_t file;
    fs_file_t_init(&file);

    if (fs_open(&file, "/SD:/temp_log.txt", FS_O_WRITE | FS_O_CREATE) != 0) {
        LOG_ERR("Failed to open file");
        return;
    }

    char data[] = "Temperature data";
    if (fs_write(&file, data, strlen(data)) != strlen(data)) {
        LOG_ERR("Failed to write data");
        fs_close(&file);
        return;
    }

    fs_close(&file);
    LOG_INF("Data logged to SD card");
}

If the implementation is successful, the output should log the temperature data to the SD card and display a confirmation message.
