EVK-ODIN-W2 Can't init() SD Card

Mbed OS
1

Trying to just write to the sd card on my board. Can’t get the sd card to init() without error. When I compile and run the following code, the board always lights the red LED.

#include "mbed.h"
#include "platform/mbed_thread.h"
#include "SDBlockDevice.h"

#define HIGH 1
#define LOW 0

//SDBlockDevice sd(D11, D12, D13, D10);
SDBlockDevice sd(MBED_CONF_APP_SD_CARD_MOSI, MBED_CONF_APP_SD_CARD_MISO,
                 MBED_CONF_APP_SD_CARD_SCK, MBED_CONF_APP_SD_CARD_CS);
                 
DigitalOut led1(LED1);

int main()
{

    int ret = sd.init();
    switch(ret){
        case BD_ERROR_OK:
            led1 = LOW;
            break;
        case BD_ERROR_DEVICE_ERROR:
            led1 = HIGH;
            break;
    }
}

and I have this mbed_app.json

{    

    "config": {
        "update_file": {
            "help": "Path to the application update binary on the SD card",
            "value": "\"mbed-os-example-blinky_application.bin\""
        },
        "sd_card_mosi": {
            "help": "MCU pin connected to the SD card's SPI MOSI pin",

        },
        "sd_card_miso": {

            "help": "MCU pin connected to the SD card's SPI SCK pin",
            "value": "D13"
        },
        "sd_card_cs": {
            "help": "MCU pin connected to the SD card's SPI CS pin",
            "value": "D10"
        }
    },
    "target_overrides": {
        "UBLOX_EVK_ODIN_W2": {
            "target.components_add": ["SD"],
            "target.restrict_size": "0x40000",
            "sd_card_cs": "D9"
        }
    }
}

Seems like a very simple thing to me and I’m here after a few hours work unable to get this to work!
