I am good with that assuming Burns is.

Yes, at least part of the errors structure is saved on a reset to indicate what happened.

The STM32L processor knows how to disable the WD when you are at breakpoints in the debugger. If the TMS does not do that, it is the only reason I can think of that there would be a problem. And just a check: Is the s/w still set up so that the errors structure is not wiped out by a reset? In other words, that the WD flags will be available after the WD triggers and the system reboots? I seem to remember that was a fair bit of hassle to make that happen and I don't just remember how I did it :-) 73, Burns Fisher, WB1FJ *AMSAT(R) Engineering -- Flight Software* On Tue, Oct 3, 2023 at 1:53 PM Chris Thompson via pacsat-dev < pacsat-dev(a)amsat.org> wrote: > Bug fixed and now the local errors structure is copied into the downlink. > > I think we should leave the WD enabled and see if it causes any issues. > Thoughts on that? > > 73 > Chris > > On Tue, Oct 3, 2023 at 1:37 PM Chris Thompson via pacsat-dev < > pacsat-dev(a)amsat.org> wrote: > >> Thanks for that. >> >> I think it all works then.

Bug fixed and now the local errors structure is copied into the downlink. I think we should leave the WD enabled and see if it causes any issues.

Thanks for that. I think it all works then. I can see the bits get set (or not when it triggers). They wdReports not making it into the downlink though. They are visible in errors.c So that is likely a bug in the way they are copied onto the frame. 73 Chris On Tue, Oct 3, 2023 at 11:35 AM Burns Fisher (AMSAT) via pacsat-dev < pacsat-dev(a)amsat.org> wrote: > Chris, wdReport is the bitmap of tasks that have called the watchdog > report routine in the last few seconds.

Chris, wdReport is the bitmap of tasks that have called the watchdog report routine in the last few seconds. When you call ForceInternalWatchdogTrigger, you go into an infinite loop. Since the OS is set not to do pre-emption, that prevents ALL tasks from running and from reporting in. It is possible that you might have called this at such a time that a different task is the one that did not report in. If you want to try having a single task not report, put a call to vTaskYield() inside the infinite loop. That will prevent the current task from reporting, but allow all the others. And yes, the console task is not monitored, so it will not show a bit missing if you have the infinite loop without the yield, and should not trip the WD at all if you use yield. 73, Burns Fisher, WB1FJ *AMSAT(R) Engineering -- Flight Software* On Tue, Oct 3, 2023 at 11:24 AM Chris Thompson via pacsat-dev < pacsat-dev(a)amsat.org> wrote: > Ok, that call works and the watchdog resets the IHU as expected.

Ok, that call works and the watchdog resets the IHU as expected. The console is not in wdReports so I could not see if the data ends up in the Telemetry. So I put the call in the PB routine that handles DIR broadcasts. We get a reset as expected when a DIR is requested. But I can't see the missing bit in wdReports. They are all still set. I need to dig a bit deeper as I perhaps don't understand how this is tracked. 73 Chris On Mon, Oct 2, 2023, 18:44 Chris Thompson via pacsat-dev < pacsat-dev(a)amsat.org> wrote: > Thanks!
