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>

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)

	set_power_on_sd(&sd_gpio, 1);

	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) {

			return res;
		}
		res = fs_mount(&mp);

		}
	} else {

	}

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

The associated function for the sdcard_disc_init(void)

	int status = disk_access_status(disk_pdrv);

	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);

Your help is kindly appreciated,

thanks in advance for your help.

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

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

[Patrice Rudaz]

Hi Vidar,

I'm Patrice, working at the School of Engineering of Sion, and I'm trying to support Nabil in his work dealing witn nrf54L15 and SD card...

I took the fs_sample project you provided and ran it on the nrf54L15 development board I have in the office. It's a version 0.9.2

I've checked that the nrf54l15's GPIOs are set to 3.3V. I'm having the same problems as with the hardware used by Nabil (see RTT output 54l15).
I also tested your .hex file and got the same behavior!

I then compiled the project for an nrf5340 board and everything works (cf. RTT output 5340).

For the 2 builds, I'm using the same toolchains, same external hardware and the same SD card:
- ncs 3.0.0
- ncs toolchain 3.0.1

Any ideas ?

Here is the project with the overlay and conf files:

fs_sample_54l15_and_5340.zip

[Vidar Berg]

Hi,

Could you please try with the .hex I uploaded earlier and with this pinout:

Best regards,

Vidar

[Patrice Rudaz]

Hi Vidar,

I already did, but here is the RTT output with the .hex and pinout provided:

[Vidar Berg]

Hi,

I was hoping testing with my FW would help narrow down the problem. The error indicates that the SD card is not responding to the commands.

So to summarize:

1. The same SD card works with the nRF5340 DK which confirms that the card is compatible with the driver.

2. Both setups are operating at the same IO voltage level.

3. The identical firmware works on my desk.

From the board picture you posted it looks like you have changed which pins are connected to the SD card module compared to the overlay Nabil included in the initial post? Have you tried to probe the lines with a scope or logic analyzer?

[Patrice Rudaz]

Hi Vidar,

It seems that the pins are well configured, according to the .overlay.

• P1.04 : SD_SCK
• P1.05 : SD_MISO
• P1.07 : SD_MOSI
• P1.06 : SD_nCS

&spi20 {
    status = "okay";
    compatible = "nordic,nrf-spim";
    pinctrl-0 = <&spi20_default>;
    pinctrl-1 = <&spi20_sleep>;
    pinctrl-names = "default", "sleep";
    cs-gpios = <&gpio1 6 GPIO_ACTIVE_LOW>; // P1.06 - SD_nCS
	sdhc0: sdhc@0 {
		compatible = "zephyr,sdhc-spi-slot";
		reg = <0>;
		status = "okay";
		mmc {
			compatible = "zephyr,sdmmc-disk";
			disk-name = "SD";
			status = "okay";
		};
		spi-max-frequency = <24000000>;
	};
};

&uart20 {
	status = "disabled";
};

&pinctrl {
    spi20_default: spi20_default {
        group1 {
            psels = <NRF_PSEL(SPIM_SCK,  1, 4)>,
                    <NRF_PSEL(SPIM_MOSI, 1, 7)>,
                    <NRF_PSEL(SPIM_MISO, 1, 5)>;
        };
    };

    spi20_sleep: spi20_sleep {
        group1 {
            psels = <NRF_PSEL(SPIM_SCK,  1, 4)>,
                    <NRF_PSEL(SPIM_MOSI, 1, 7)>,
                    <NRF_PSEL(SPIM_MISO, 1, 5)>;
            low-power-enable;
        };
    };
};

With the logic analyzer :

• nrf54L15

• nrf5340

The GPIOs seem to be correctly assigned. However, the SPI frames are not the same.

• Is there anything special to do with the nRF54L15 in terms of hardware?
• Or a special configuration to put in the prj.conf?

Kind Regards
Patrice
