For informational purposes, I'm not a new MiSTer user. I've had my DE-10 for about 4 years and I've run various versions of MiSTer during that time. I've even tried my hand a few times and developing on several of the cores.
But life goes on and I got busy. My last install was from 2020 or so ... so I decided to completely fresh install.
Being what I had on-hand, I copied the new image onto the micro-sd using dd on FreeBSD. This boots --- and I choose f12 to get the menu and then I choose the upgrade script. I'm using ethernet --- because it's convenient here.
That-all seems to run fine. No complaints on the screen. It then says it's rebooting in 10 seconds. I didn't notice this for awhile, and it seems to go to "press any key" after that. Nothing happens. So I re-flashed and started again. If I press a key right around the 10 second mark, I get a few seconds of the snow-screen menu reappearing ... but it doesn't reboot. If I manually cycle the power, it doesn't show video (although the cylon-lights seem to indicate that things are running).
I've repeated this 3 times so far... help?
