I set up my banana pi m2 berry with an SD card and now I want to use an SSD as a boot drive. My problem is that I tried to connect the SSD just for checking it’s content, but I could not see it using the lsblk command (I use a custom image of Armbian). I connected the SSD to an external power source and than I could see it’s contents, so I think the problem when connecting directly to the BPI for power is the insufficient supply (I used a phone charger adapter and my computer too). Another thing is that the cable I use for powering is from an old power supply that I converted, but maybe that should not be a problem.
My question is how big of a power supply do I need is 3A enough?
