I have a new Mayflyv1.1 board and it does not recognize the microSD card (it’s side loaded into the board without any adapter). I am using the mayfly1_TempHumidLight_simpleLogger example with no changes. When I turn on the Mayfly board, I get:

Mayfly SHT40-Light Logger
Error: SD card failed to initialise or is missing.

I’ve tried a couple of different microSD cards, both of which work for other devices. How should I approach debugging this or might it be a hardware problem?
