micro-SD card does not work on mangOH Red


#1

I tried to install 2 different SanDisk cards: 16GB and 8GB.
Both the cards do not work.

What can cause problems ?


#2

Did you install the SD cards before powering up the unit? I think there is a limitation that prevents hotplug from working.


#3

I have powered the board after the card had been inserted
