I'm trying to build openWRT for an Arduino Yún. The one on the site doesn't work right. Best I can do is get it to complain about rtc at boot. I was able to unbrick it and install a fresh build of openWRT. Now, it only seems to get so far. I suspect either tty get handled weird or I broke the build somehow. I can't connect with ssh or webui. It doesn't respond to serial either. What do I do next?
