I bought an OPi Zero, the extension board, a 1/8-to-rca audio/video cable to plug into the AV jack of the extension board, and a 16 GB SDHC card. Loaded Armbian Stretch onto it, plugged in ethernet without any of the AV stuff just to start. The Pi doesn't even show up on my router settings so I cannot access it via Putty or any other SSH program. I turn it off, attach the extension board and av cable, and plug it into the TV in the hopes that I can start working on something with a USB keyboard...nothing shows up on the TV. I'm hoping that's a software issue and not an issue with the actual extension board I bought. I know for a fact it's loading Armbian because I can actually access it via USB through Arduino IDE, I just can't access it with anything else, and I can't do anything more in the Arduino IDE than execute simple commands, I can't edit a file in nano or vim or do much of anything else with it. Maybe I can use "echo -e" to write some important config files but I don't know what they would even be and I don't know why it just isn't working in the first place. I'm trying to perform the same steps I see in Youtube videos about the board and I'm not even getting past being able to control it remotely.
