There are two install emmc files in armbian amlogic verison by balbes150.  install-aml.sh and install-aml-s905-emmc.sh.

What's the difference between these? If install armbian to a S912 TVbox emmc, which one should be choosed?

Can you please post the content of both the files?

I am not sure so it will be better to read the content and understand what it is trying to do,

 

AFAIK I have been using the latest iteration of the install script which includes support for RGB YUV for aml devices which have green screen issue.
