Orange Pi Zero Second SD Card using a GPIO for CS?

[Sebastian Heyn]

Hi,

 

for the raspi it is possible to add a second SD Card...

 

I was wondering whether armbian brings the necessary kernel modules (mainline) to achieve this functionality? My approach is not speed, I need tight space so a second SD without USB adaptor would be excellent...
