So all your RPi2B's are v1.1 and so must be used as armv7. Good to know. (Note FreeBSD's armv7 snapshots do not provide the .dtb for v1.2 or for RPi3B* 's . So booting as armv7 is not supported as the snapshots are configured.) > I've added the config.txt files to the netmap at > http://www.zefox.net/~fbsd/netmap Thanks much. If/when an experiment uses any adjusted/replaced config.txt , please be specific about the variation at the time. That includes if/when you make www.zefox.org (an aarch64) use the standard config.txt for aarch64 with force_mac_address added, instead of it being partially based on the armv7 config.txt . One thing still missing for the reporting of the specific recent experiment is: what was the powerd status of nemesis.zefox.com ? Always indicate the powerd status for the RPi*'s at both ends of the serial line involved in the failure (GIO end and tip end, making clear the exact association). > In principle both /etc/rc.conf and /boot/loader.conf might > be relevant, but adding them will increase clutter. As stands, I'm depending on your judgment about those files' full content being relevant or not. One thing that is relevant is the various powerd status's for each specific experimental variation's serial line(s) with a failure. One or more such files are likely involved in control of that status on each of the 2 RPi*'s involved. > Please > indicate if it's more help than harm.

But you earlier reported a failure involving the serial line between nemesis.zefox.com and www.zefox.org and reported that, for that experiment, www.zefox.org had powerd in use. You never indicated the powerd status for nemesis.zefox.com in that experiment that produced the failure. I still want to know what it was. > Thanks for reading, and I hope the netmap makes the > conversation easier to follow. Sure does avoid me having to guess at things. Thanks. > If not, please say so. I like the explicit extra information that you provided. === Mark Millard marklmi at yahoo.com
