HW3 2019.16.2 Waiting room

[kingjones94]

I’m really curious about the touch-screen display. Does it have its own CPU/GPU or is that external? I’m guessing it’s probably an Android device...

I don't think its android. Its their own custom hardware

Someone correct me if I'm wrong but the display/media is controlled by the MCU (media control unit) which is on version 2. That's a separate component from the computer that handles driving functions (neural network, auto steering, cruise control, etc.). I think they switched to version 2 of the MCU over a year ago and they aren't different in HW3.

However, since the dash cam videos are encoded with a different codec in HW3 that particular feature must be handled by the HW3 computer. Not sure exactly where they draw the line of functions handled by the MCU vs HW3/2.5 computer.

Anyone have a better understanding?

I remember reading (and my own experience hasn't proven otherwise) is that the model 3 has three systems. You have the MCU . You have the drivetrain system which handles all your driving logic and battery management. Then there's the autopilot computer which handles autopilot and its sensors.

So you've already figured out that the autopilot computer is the one doing the encoding for the dashcam and sentry modes. This is because it turns out the MCU actually doesn't have connections to those cameras! I believe the MCU only has a connection to the backup camera, which makes sense since it has to be displayed onscreen for the driver.

Interestingly.. I think Tesla could probably add the backup camera to sentry mode but not dashcam. This would be because I don't think the MCU could encode the backup camera while you're driving and using the MCU.

This separation is also the reason that a birds eye-view parking mode can't come through a software patch (well the car lacks the necessary cameras in the first place) But either way- most of the cameras likely can't be displayed in real-time by the MCU because they're routed to autopilot only... UNLESS the bandwidth from autopilot computer to the MCU is fast enough to stream video.

The current MCU in model 3s and new S/X is an intel atom system apparently the E3950. Old S/X used nvidia tegra. Both run linux.

I love how I wake up each day hoping today is the day...

 

[Wado]

I'm really looking forward to getting the update, can't stop checking the boards and looking at my phone. Hopefully the HW 3 software catches up soon.

haha meanwhile I'm dreading the day tesla nerfs my range from SR+ to SR.

 

[kingjones94]

nobody from hw3 got the update yet????

 

[Tholland]

Nope not yet! Hw 3 cars are still on hold.

 

[AustinM3LR]

Still waiting here too. Feel like I'm driving a "classic" with the old software.

But still enjoying every second of it.

 

[rpreuss]

HW3 and still waiting for update.

 

[AustinM3LR]

Looking at TelsaFi it looks like they took the Memorial Day holiday

Just a trickle. Probably people connecting to wifi for the first time since it was enabled for them.

 

[WilliamG]

Waiting is fun. Anticipation often more fun than the actuality.

 

[mbdionio]

still stuck with 2019.7.106

 

[AKinDC]

With the anticipation on this thread, you'd think the update would double your range.

 

[mbdionio]

Just wanted to try out Sentry mode which is missing from the current firmware. Wishing for an easy root access.

Yikes you might want to put in a service request on the app and have them check that. Mine delivered on 5/3 was on that version but had already downloaded 2019.12.1.2 and I installed as soon as I got home. I'd be shocked if there are still cars out there that haven't been approved for the 2019.12.x update. Might be stuck in the process somewhere.

Also I'm sure you know this but here's the obligatory "make sure you're connecting to wifi" admonition.

 

[mbdionio]

yeah connected to wifi at home. I'll make a service request. got the same color as yours but with white seats.

Agree with this. I got my car 5/2 and had that older version, but within a day or two was bumped to 2019.12.1.2 where I've stayed.

Same here took delivery on 5/9 and it had finished installing when I got there to 12.1.2.

What's the criteria to get a firmware update? Some intern in Fremont randomly selects who get to be updated per day?
