Thanks! Completely forgot about that, everything is working as expected now.

Hello,

What kind of SD Card reader do you use? And what is it's required input voltage, and more specifically, what voltage does it accept as logic high on the signal GPIOs?

By default, the VDD and GPIO voltage of the nRF54L15 DKs are lower than they were on the nRF52840.

You can, however, open the nRF Connect for Desktop -> Board Configurator, select the nRF54L15DK, and adjust the VDD output to 3.3v, and see if that works with your SD Card reader.

Best regards,

Edvin
