@Geronimo

you have one of the most problematic board ( I own many of them, but all are working having only some problems on reboot because of wrong miniloadr, see in this discussion ) 
it has rk 3228
ddr2
nand

as you did , me too in the beginning tried to flash some miniloaders, and this is not good because some of the have different 1T / 2T settings. This was an error !!!

so far, actually , you have to do one thing: grab a usb/ttl converter ,(go search for one)  remove sd card, use the 4th pin of sd card counting from right ( count also the 2 small pins of sd card reader switch)

YES !! on that pin there is a serial uart

and give here the early log of the board , including ddr version 

i can give you for sure that that board will work with linux, but you have to stay on kernel 4.4.189 , even if don't expect exceptional benchmarch

Yes, I work with microcontrollers so I have a few of those lying around. Man, what a weird place to put the serial at.

Is it these? What would be the pinout?

Where could I find armbian images running that version? The only images I could find online run on 4.4.194.
