nRF5340, QSPI and micro SD

[Göran Nordahl]

Hi,

Is it at all possible to use the QSPI interface of nRF5340 to interface a micro SD card? Is sending custom instructions combined with long frames, as suggested here, the way to go?

Best Regards,

Göran Nordahl

It does not seem like it is possible to use QSPI with an SD card unfortunately: https://devzone.nordicsemi.com/support-private/support/264659#permalink=640626

"Using SD card in any other modes than SPI would require a licence from the SD card association, link. Even if we had such an example, we wouldn't be allowed to publish it. Hence only SPI examples are shown for SD Cards."

Best regards,

Simon
