Hi… i’ve a BananaPi with lakka, butim not abe to enable tv out, it works only in hdmi… there is no config.txt in /boot and i dont know how to enable or force tvout (av)
Some idea?
i find something about bin2fex… i’m working on it 
It sounds like you’re on the right track with bin2fex. This forum post, although it’s about overscan, gives an indication of what to do and this page gives details of what you can put in the text version of the config file.
Uh! Thanks!
Ok, installed sunix-tools on my Mate pc, copied script bin from SD, converted script.bin to script.fex, ( bin2fex script.bin script.fex ) changed with nano in [disp_init] section:
screen0_output_type = 2 screen0_output_mode = 11
saved, comverted script.fex to script.bin ( fex2bin script.fex script.bin ) copied script.bin to SD
now tvout works
Lakka runs fine on my minicoinp, with a 7" monitor, all games, all mame and neogeo roms
now searching how to enable audio jack (audio set by default to hdmi…)
workin on, again
