Ignore my comment regarding CAC which I see now the car is on charge :-)

Just to add a little more to Nikki's report…

I've seen some odd behaviour with SOC… if you see the attached photo's you'll see STAT report SOC as 46% and then 50% even though the commands were sent within a minute of one another (approximately). You'll also see the app and car displayed 52% and 92m at the same time.

I also note that the ODO reports 0.0 mil and I see no CAC in response to a STAT command. Is this expected behaviour with this firmware?

Firmware version reported in the app is 2.3.1/TR/V2

All the best,

Just a head up:

I flashed my Twizy firmware and it immediately started working.

I flashed Kevin's firmware on his Roadster, and it took about 10 minutes to start working.

Not sure why -- but thought you'd all appreciate the report. :)

I've got a 35 mile round-trip tonight to Bath, and about 120 miles of work-related travel this week in the Twizy, so plenty of time to test it!

I've had GPS streaming enabled during the last days, and neither GPS nor GSM connectivity are good at the moment. May be related, as streaming means more data communication. But still that should not lead to RAM corruption.

Mark,

I've got the last but one version in my car, just lacking the new VEHICLE commands.

I've got two open issues, the minor one being to raise the 12V auto acquisition time even more, as the faults have become better but it's not yet perfect. I'm trying 20 TAD now, as we don't need to be fast on that A/D conversion.

But a major issue might have turned up: I've just had the second RAM corruption within three days. Effect:

MP-0 c32,0,106,119,*-OVM-DebugCrash,2013-04-14 14:06:40,0,2.2.7/RT2.6.4/V2,0,0000,20
MP-0 c32,0,107,119,*-OVM-DebugCrash,2013-04-14 14:25:13,0,2.2.7/RT2.6.4/V2,80,0020,61

As there is no checkpoint 61, this means at least the debug variables have been overwritten, was the same with the first occurence (but other values).

As the module behaves weird afterwards I suppose more variables have been corrupted.

I've looked through the last changes several times, I'm pretty sure none could have introduced this kind of bug... if I'm the only one experiencing this, maybe I've got some hardware issue as well?

I'll continue checking the source for possible buffer overruns...

Regards,
Michael

I've just built from latest sources, v2.3.1. This is a release candidate, and I have 24 hours to test before i need to send it to China.

It is in my car now, and seems ok. I'll do more testing tomorrow.

I'd be grateful if others could grab it and put it in their cars to ensure there are no major problems.

Regards, Mark.

All seems ok.

I've committed and pushed my changes (just the stp_ltf_h() function, and change to report cac as 999.99 to server).

I've just flashed and it will go in my car tomorrow.

Regards, Mark

Mark,

I just checked in my latest changes.

In net.c I added the pending send check also to the new net_notify_errorcode send, I think that should be correct, but please have a look.

I saw the new stp_f() function, but I don't understand it's purpose yet. What's the difference to my stp_l2f() function?
Btw: l2f = "long to float" -- I think "_f" should be reserved for an stp call with a real float type parameter, if we once really need one.

Regards,
Michael

Nikki,

yes, see attachment.

I could not make out any possible source of that strange error I had yesterday (completely garbled data).

I made a clean build with a freshly started MPLAB and got no errors up to now.

May have been something completely different, not related to my last changes.

Regards,
Michael

Michael,

Any new firmware for me to test this weekend?

Nikki.

I think I was a bit too fast on this, Nikki, don't use that version, it seems to have some new bug causing frequent crashes... :-(

Mark, Nikki,

I'm currently trying to fix a last bug with the power statistics (the distance counter still went wrong), and I'm trying to get the 12V A/D conversion to work without these strange "peaks" by raising the automatic acquisition time. I will finish testing this ASAP or tell you in time before sunday.

Nikki, I attached the latest version in case you'd like to test as well.

Regards,
Michael

China is bugging me for final firmware for the next batch of hardware. I need to get them this early next week.

I've committed what I need for the Tesla Roadster (and framework). Last outstanding small change to make is to send CAC as 999.99, rather than the current 99999, using Tom's new library function.

Michael B & J: can you check Twizzy and Volt/Ampera, to see if everything is ok with current firmware or there is anything you need changed?

I plan to cut release candidate for 2.3.1 on Sunday.

Regards, Mark.
