My vanilla V3 (with RPi4) Zynthian has been running along well for quite some time now and this afternoon I did a software update. That was the end of that. Rebooted to the Zynthian logo and there was no way out of it.
Instead of spending hours messing around with it I backed up my Snapshots and decided to just do a clean install. Downloaded the latest stable image, burned it with Balena and now I’m dealing with a Zynthian that shows the UI for a few seconds, shows the Zynthian Logo and repeats. I hooked up via the webconfig over ethernet. The webconfig works fine except when I make changes to the config and it requires a reboot it never reboots. It just keeps cycling the UI. So even though I change it to Custom Kit, Zynscreen 3.5, etc, none of these changes stick because it won’t reboot.
As I could not get it to reboot or shutdown, I finally just got mad and yanked the power to shut it down. Strangely, when I plugged it back in, it came up but no longer in the infinite UI reboot loop. It appears my changes stuck after a power cycle.
I’m not filled with confidence but at least I appear to have gained control again.
Any thoughts on why I was stuck in a UI cycling loop like that?
Please post a screenshot of your webconf dashboard.
Zynthian has a supervisor wrapper that detects the exit code of the core python code and reacts accordingly. If there is a bug in the python code then it may exit with the wrong code and result in unexpected results including showing the error screen, failing to reboot, etc. The cause of this is often recorded in the log so it may also be beneficial to provide logs which can be viewed in webconf.
Captured initial log, went into debug mode, and back to normal UI mode below.
