I am attempting to boot my Orange Pi 2G-IoT for the first time but I am getting an error on each flavour of OS (raspbian server, ubuntu and armbian) I attempt. I have even used different SD cards but still no avail. 
Card Used : 
- San Disk 8 G.B. Class 10
 - San Disk 16 G.B. Class 10
 - Samsung Evo 32 G.B. Class 10
 
 
  
These cards are working properly on other boards. I have successfully booted Orange Pi Zero with San Disk 8 G.B. Class 10 and San Disk 16 G.B. Class 10 SD cards. Samsung Evo 32 G.B. Class 10 card works seamlessly with my Raspberry Pi 3. 
 
Serial Debug Connection Settings : 
- Baud                             : 921600
 - No. of Bits                     : 8
 - Parity                            : None
 - Hardware Flow Control : None
 - Software Flow Control  : None
