Hi ..  
 
Yesterday i have received the orangepi zero 2 board. I have tried with 3 different microsdcards .. and the results are the same.  
Only in android image and using PhoenixCard app i can see the boot process from the serial port.  
I am using a 5V 2A power supply. 
Microsd cards .. 2GB, 4GB, and 64 gb transcend and Sandisk. 
 
Here you have the boot output when using android image :
