Yep, I followed the steps in the getting started guide.
SHA256 hashes from 7-zip match those in the text file. I use etcher and pass the verify steps with no problems. I've tried 3 or 4 SD cards, three of them the red/grey Sandisks (and a PNY I had sitting around). I've tried 3 different Canakit 2.5 amp power supplies as well as a few non-Canakit 2 amp supplies.
The funny thing is it seems to run the Orangepi provided distros OK, but these are terrible, out of date software that I don't trust not to have Chinese trojans embedded.
I cannot run armbianmonitor because on the few occasions I have actually gotten to a prompt, running any command results in a segfault, filesystem error, or just plain lockup, including commands like "ls" and "sudo apt-get update" and "passwd". Usually when I try to book an armbian flashed SD card, I just get a blank screen.
