Hi

What kind of hardware are you using? 

Have you ensured that the SD card is correctly connected to the nRF52 device?

Best regards

Hi

Have you tried to scope the SPI lines to see if there is any communication happening between the nRF52 and the SD card?

Hi 

Which Zephyr version are you using?

Is it a tagged release, or the master branch?

I have a SD card laying around and will try to reproduce your issue tomorrow. 

Best regards
