Thanks for the response, but my issue was more about a power bounce required to come back from the lockup I am attempting to log. Pulling the plug while its locked up in debug logging will wipe the desired log on reboot. Or no?
I am about to see if I can create the necessary debug log, and, if the service is still available while locked up, try to scp the file off of the Vero before i pull power to reboot.
Short of that, perhaps Im mistaken about the power cycle wiping the debug log? I’d love to know for certain. I will be back soon with a log, hell or high water!
