Hi Kalkov I really need rca working i did two test with the same config on my pi2 with linux and pi3 with android. So pi2 work fine, pi3 pre-boot work on rca with the good config.txt file but when emteria os boot the screen become grey and nothing happen till I plug hdmi cable. So when i plug hdmi screen become black and tv say no source so if I switch to my hdmi input emteria boot, so it looks like emteria wait absolutely for hdmi to boot, please perform and fix this fonctionality, i really need it on my car i don't have hdmi. Also with hdmi to rca converter quality is too bad than real rca signal.
Thanks in advance.
