Hello sicxnull,
I've been following your topic since the beginning as I bought the same Android STB and have also been trying to run it on Linux since August 14th !
With termux on the stock android there seems to be 2Gb of RAM, but on your Armbian “Minimal/Server” build I'm getting down to 914Mb.
On stock Android :
total used free shared buffers
Mem: 1.9G 907M 1.0G 6.4M 524K
-/+ buffers/cache: 906M 1.0G
Swap: 1.4G 138M 1.3G
On your Armbian Build :
Any clues about this gap?
Is it because RAM is shared with graphics?
cya~
