Newbie here. 
 
I have jsut acquired the OrangePI 4 LTS. Notice it came with some version of Android. I used windows and mac to flash a brand new sd card with linux distro. I tried debian, armbian and ubutu. 
After flash, inserted the sd on to OPI it never runs the OS. Is there anything I should do first in order to make the OPi botto from the sd ?
