Failure to get SDHC to work with NRF5340DK

The issue for me turned out being the SPI Max Frequency setting. The max I was able to get this card/module combo to support is 15900000. I am able to mount the FS now on the SD card. If 15900000 does not work try a lower frequency.

Hi,

The pins you reference does have some other uses so there could be a conflict. You can see in the docs here:https://infocenter.nordicsemi.com/topic/ug_nrf5340_dk/UG/dk/connector_if.html?cp=3_0_4_3_5 and here https://infocenter.nordicsemi.com/topic/ug_nrf5340_dk/UG/dk/hw_external_memory.html?cp=3_0_4_3_4.

The external memory does occupy some of the pins.

Disable spi4 and then use the spi4 pins in sted should "easier" since they are not used for anything else.

Are you using spi3 for something else? or could that be an option to try.

Regards,
Jonathan

I'm experiencing the exact same error with the same board and I have qspi commented out and went over the common dts file to ensure the pins are not being used anywhere else.

Hello,

I get exactly the same error with other pins (15, 16, 17) and (8, 9, 10)-> with qspi disabled.

Hi,

the " <err> fs: fs mount error (-5)" error is an I/O error. The netcore has uart0 with pin 33, try to use something else or edit the nrf5340_cpunet_reset.c directly.

Try to use some other pins and see if you get same error.

Jonathan

Hello Jonathan,

I started with the non secure and switched with the secured one but have the same results in the two cases

Did you build for secure or non secure?

Maybe someone from Nordic could help us with the SDHC of the NRF5340 ? I have no other idea…

Here's my output from the logic analyzer after I found I had the analyzer hooked up wrong. Also, my project.

With the logic analyser, I can see this weird SPI behaviour on the SD Card...

CS is down.SCK (14) is beating. MOSI and MISO are down.

I cannot get why SPI is different on the nrf5340 versus the nrf52 series?

Debugging this in Segger I see the problem at disck_access.c in diskaccess_get_di(). The loic with SYS_DLIST_FOR_EACH_NODE(&disk_access_list, node){ } is skipped because disk_access_list has nothing in it.

It appears disk_access_list is not being populated inside disk_access_register(). I set a breakpoint at the beginning of the function, but it's not being hit.

Here is the line of code: https://github.com/nrfconnect/sdk-zephyr/blob/main/subsys/disk/disk_access.c#L33

Here is the value of disk_access_list & disk at the end of disk_access_get_di():

Side note: "SD" is passed into diskacces_git_di().

I tried both as well without success as I found both online.

I am working through this same exact error on the same board and same Zephyr version.

My overlay looks very close to yours with the exception of my pin definitions. Why do you not have cs-gpios set to GPIO_ACTIVE_HIGH like what is in the sample? I tried both ACTIVE_LOW and ACTIVE_HIGH with the same result.

My SD card is formatted FAT and is a 32GB SDHC.

I hooked all pins up to a logic analyzer and both MOSI and SCK go high on boot/reset.

Here's the project on github: github.com/.../fat_fs
