SD Card: Error mounting file System error: -134

[nbh]

Hello,

I am trying to use an sdcard with the nrf54l15 DK board with the 2.9.1 sdk. However I encounter "<err> fatfs: Storage init ERROR! error: -134" when calling the disk_access_init() function

My code described below is based on the fatfs example

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

#include "hardware/gpio.h"
#include "sdcard/sdcard.h"

#define DISK_DRIVE_NAME "SD"
#define DISK_MOUNT_PT "/SD:"

LOG_MODULE_REGISTER(main);

static const char *disk_mount_pt = DISK_MOUNT_PT;

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

struct gpio_dt_spec sd_gpio = GPIO_DT_SPEC_GET(SD_ENABLE_NODE, gpios);

int main(void)
{
	LOG_INF("Starting program");
	set_power_on_sd(&sd_gpio, 1);
	int ret_pinConfig = gpio_pin_configure_dt(&sd_gpio, GPIO_OUTPUT_INACTIVE);
	k_msleep(250);
	LOG_INF("Pin Config status Code %d",ret_pinConfig);
	
	sdcard_disc_init();
	mp.mnt_point = disk_mount_pt;

	int res = fs_mount(&mp);


	if (res == FS_RET_OK) {
		LOG_INF("Disk mounted.\n");
		/* Try to unmount and remount the disk */
		res = fs_unmount(&mp);
		if (res != FS_RET_OK) {
			LOG_INF("Error unmounting disk\n");
			return res;
		}
		res = fs_mount(&mp);
		if (res != FS_RET_OK) {
			LOG_INF("Error remounting disk\n");
			return res;
		}

		if (lsdir(disk_mount_pt) == 0) {
			if (create_some_entries(disk_mount_pt)) {
				lsdir(disk_mount_pt);
			}
		}
	} else {
		LOG_INF("Error mounting disk.\n");
	}

	fs_unmount(&mp);
	LOG_INF("Exiting program. \n");
	return 0;
}

The associated function for the sdcard_disc_init(void)

int sdcard_disc_init(void) 
{
	/* raw disk i/o */
	static const char* disk_pdrv = "SD";
	uint64_t memory_size_mb;

	uint32_t block_size;

	// Re initialize the SD Card
	int status = disk_access_status(disk_pdrv);
	LOG_INF("Disk Status: %d", status);
	int res = FR_OK;

	if (status == 1){
		res = disk_access_init(disk_pdrv);
		LOG_INF("DISK Acces init code %d",res);

	}
	if (res == FR_OK) {	
		res = disk_access_ioctl(disk_pdrv, DISK_IOCTL_GET_SECTOR_COUNT, &block_count);
		if (res == FR_OK) {
			LOG_INF("Block count %u", block_count);
			res = disk_access_ioctl(disk_pdrv, DISK_IOCTL_GET_SECTOR_SIZE, &block_size);

				LOG_INF("Sector size %u", block_size);
				memory_size_mb = (uint64_t)block_count*  block_size;
				LOG_INF("Memory Size(MB) %u\n", (uint32_t)(memory_size_mb >> 20));
			} else {

		} else {
			LOG_ERR("Unable to get sector count. error: %d", res);
		}
	} else {

Your help is kindly appreciated,

Hello,

Before I try to reproduce this on my desk, please try increasing the IO voltage to 3.3v if you haven't done so already. The default voltage is 1.8v and may not be supported by your SD card. The IO voltage is adjusted by changing the VDD in the board configurator app in nRF Connect for Desktop:

Best regards,

Vidar

[nbh]

Hello thank you for your answer, as you predicted the default volatage was indeed set 1.8V.

However i still encounter the same issue after setting the voltage to 3.3V as described in the logs of the original post.

Thanks

Nabil

[Vidar Berg]

Hello Nabil,

Thanks for confirming that you see the same with 3.3v. I have tried this on my desk now and confirmed that it works here. Please try with the hex file below and see that you get the same result as well. The difference is that I assigned MISO to P1.7 because P1.3 is not routed to the pin header by default (see Configuring NFC pins as GPIOs).

Hex file

fs_sample.hex

Test project

fs_sample.zip

Pinout

Best regards,

Hello Vidar,
After inspecting the overlay file i noticed that the disk-name property inside the mmc node is not allowed, and generates a build error

devicetree error: 'disk-name' appears in /soc/peripheral@50000000/spi@c6000/sdhc@0/mmc 
in C:/****/fs_sample/build/fs_sample/zephyr/zephyr.dts.pre, 
but is not declared in 'properties:' in C:/ncs/v2.9.1/zephyr/dts/bindings\sd\zephyr,sdmmc-disk.yaml

Just to make it clear i'm building for the nrf54l15dk/nrf54l15/cpuapp using the 2.9.1 sdk.

Also i forgot to mention in my original post that my board is reconfigured to use the NFC pins as GPIOs

(And checked with an Analog discovery tool)

Thanks

[Vidar Berg]

Hello,

I took a chance on using SDK v3.0.0 instead of v2.9.1 not expecting any major changes, but I see the binding was updated to include the name property between these two releases: https://github.com/zephyrproject-rtos/zephyr/commit/a1dc0b8b3e97542ca9f0c84cba37067710b61ccb. Anyway, are you able to test with the hex file I uploaded to verify the your SD card is supported?

Best regards,

Vidar
