SD card with Zephyr SDK 2.4.0

[Hinal Tailor]

Hello

I need to do SD Card with nRF52840-DK. I have referred (zephyr/example/subsys/fatfs) sample program, based on that I have made one new project and also made overlay and conf file. In that code. I have used SPI1 pins which you can find in attached document.

.conf File:

Overlay File:

SPI1 pins according to DTS file.

sck-pin = <31>;

mosi-pin = <30>;

miso-pin = <40>;

 

I am facing SD Card mount error while checking signals on SPI pins with the help of logic analyzer but no signal was displayed in analyzer on any pin.

So, I need to know what I have to change or please suggest some reference to do this as early as possible.

Thanks & Regards,

Hinal Tailor

I'm not sure what's causing the mount error, check out this case and see if it helps you with the error. It may not be relevant since it's based on an older NCS version and nRF9160 was used. Please tell me if it wasn't helpful and I will dig deeper into this.

Best regards,

Simon
