(that doesn’t include scheduled events, only the ones from OvmsEvents::SignalEvent)

I think the issue was most likely triggered by the egpio events introduced a while back. Agree with Thomas that this is most likely just a simple queue overflow. Perhaps EGPIO is flapping at startup, causing a flurry of these egpio events? I am guessing that this is aggravated in Greg’s case as he is doing some egpio and power work for HUD control.

I’ve increased the OVMS_HW_EVENT_QUEUE_SIZE to 40 on my test build, and just released that to the production server (for edge). As this sdkconfig file is not included in github, I recommend all developers do the same for their local builds.

@Michael can you set the same on your production build server?

@Greg can you check your existing firmware boot (via usb) and check for 'queue overflow, event '%s’ dropped’ style messages on startup (probably around the time is says ’Starting USB console…’.

@Greg please try the edge 3.2.008-126-g0291d03 firmware. Update to it, reboot, and see if ‘metric list version’ shows the version correctly. Hopefully this resolves (or works around) the issue.

Regards, Mark.

Maybe OVMS_HW_EVENT_QUEUE_SIZE is just too small now, with the added events during boot and async event processing?

The issue was on boot, the events: SignalEvent: queue overflow, event 'system.start' dropped in some case.

the problem was the egpio settings in OvmsVehicleSmartED::ConfigChanged(OvmsConfigParam* param)

Betreff: Re: [Ovmsdev] Double updates - Normal?

Just had a thought.

Events used to be synchronous, but we switched to deliver in a different task. Maybe the startup sequence relies on that in some way.

Seems identical. The changes don’t seem to affect the dispatch of the system.start event.

I think it must be a race condition.

Mark,

a similar issue was happening on some Smart ED and fixed by Dimitrie later on:

https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/issues/293

I thought that was a Smart specific issue, maybe I was wrong.

Still stumped…

The OTA code doesn’t call GetOVMSVersion(), but instead just looks at StandardMetrics.ms_m_version (which we know is blank). That is why this is happening.

But why is StandardMetrics.ms_m_version empty (as is the hardware value as well).

The ovms_version code hooks into ’system.start’ event, and sets the version and hardware metrics. So, obviously that is not being called. That event is raised just after ’Starting USB console…”. The event is also listened to be ovms_time, ovms_mdns, and swcan.

MDNS outputs “Starting MDNS” when it sees that. The ovms_time sets the environment variable TZ. Your car is showing:

ovms> time status

...

Vehicle Response:

Time Zone: Not defined

UTC Time: 2020-01-30 05:00:53 UTC

Local Time: 2020-01-30 05:00:53 GMT

Provider: None

So looks like TZ is not being set. Presumably that means the call is not happening. I had a look at the ovms_events code, but can’t find anything obvious.

So, tried a hacky test:

ovms> metric list version

...

Vehicle Response:

m.version

ovms> event raise system.start

...

Vehicle Response:

Raising event: system.start

ovms> metric list version

...

Vehicle Response:

Can you try to boot from USB (module reset) and provide the serial boot log? Particularly around the lines ’Starting USB console’.

Maybe a race condition at startup, or some other issue delivering events early on?

Only other thing I see are some scripts on /store/events regarding vehicle on/off - perhaps you can try disabling those to see if they trigger the issue? I tried recreating them on my box, but couldn’t repeat your problem.

Regards, Mark.

Greg,

It seems your car can’t pickup currently running firmware version:

By comparison, here’s mine:

Your m.hardware metric is also blank.

I’ll keep looking, but at the moment this seems bizarre.

Hi Mark, Michael,

Seems like what is happening is that the module keeps thinking a new
update is available. Today was especially active for some reason.
Screenshot of the Android application's log screen, attached. All
versions appear to be the same. The car has simply been sitting in the
garage on WiFi; no transitions of network access.

Output of 'ota status' attached as well.

Sorry, but I don't appear to have logging enabled. What specifically
would you like logged?

Greg

Mark Webb-Johnson wrote:

Not normal. Can you send us the logs. Also the output of ‘ota status’ would be helpful.

Are you sure this isn't just a notification of the update, and is the update itself? Perhaps a screenshot of the double notifications you receive?

Regards, Mark.

Hi folks,

I moved my car's OVMSv3 to the Edge firmware a bit ago, and notice that
every update seems to be doubled. Besides being a bit annoying, it ends
up without a previous version to fall back to since both partitions end
up being the same.

Is this behavior normal? Can it be prevented?

I'm only on Edge because of the bug in obd2ecu, and will probably move
to EAP after we get an EAP build with the fix in it. Is the behavior
the same there?

I used to be on Main, and all seemed fine there.

Thanks,

Greg
