samsung device insights This is a topic that many people are looking for. bluevelvetrestaurant.com is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, bluevelvetrestaurant.com would like to introduce to you Firmware update over the air insights and live demo. Following along are instructions in the video below:
“Let s have a look on that how does it look. And what is the the difference of a firmware update that as it is done currently in the let say in a traditional manner. When the vehicle comes into a garage. It is hooked up to a vci and basically a pc on wheels is coming to the to the car and there is running all kinds of diagnostic software on this pc first off determining the status of the vehicle.
What kind of issues are there inside the vehicle. What is their current status which firmware versions and so on and then the update package is individually configured on this pc. And with a connection to the oem back end. And then of course.
The update is eventually run from this pc into the into the car this can take several hours actually and and this pc basically does all the orchestration of the update over the different embedded controllers in the car so when we go to the over the air update process. We need some additional. Very obviously we need some additional parts like this ecu that has been very prominent today. The connectivity unit first off this this is very essential of course to provide the connectivity over the air into the body cloud from the car.
But this also serves for the purpose to run this actual flesh runtime. Because there needs to be some intelligence in the car that takes over the part of this workshop pc. Before and this could also be in the ccu or actually this could also be in any other controller in the car that is powerful enough because needs some some calculating power..
And you need some of course storage depending on how big the updates are that you need to run. Yeah. So what is the update floo for an over the air update. It starts with an initial authoring step in this initial authoring step.
Basically the update package is configured. So here. The engineer puts together the the content package with all the meter information and diagnostic sequence. So a diagnostic sequence could for example be what what needs to be the state of the vehicle.
When the update is run does the battery have to be at a certain level adjusted vehicle have to be in sent and sten sture. Probably mostly it has to be is there a driver interaction involved or is it a silent update. And all this kind of information is put together in the authoring step. This is uploaded in the boshy iot cloud and then all these iot services come in that run on the cloud like in the vehicle management the the firmware management.
Where basically these update packages are being managed rollup management and of course. The very important part is also the reporting reporting and analytics. Because all this of course needs to be needs to be documented and traceable also in and this is also very important part and and of course..
What we see on the right side. All the security related services key management certificate management encryption and decryption this will not be a focus of this talk. But this is of course certainly very important point of firmware updates that go into the vehicle power train and then eventually the vehicle connects to the bottie cloud. It asks in most cases.
Most customers look at just a regular polling. Looking for updates as they re checking for updates is their new firmware available for me and and then the content. If there is not that available. It s being downloaded into the vehicle and then of course.
The information of the current status is going back you have to do here with a lot of dumb embedded. Rollers and the vehicle update is a lot more complicated than just an update of let s say. A smart device like a like a smartphone or a pc. Because here usually typically an update is not just one concerning one controller.
But it s going really baseline driven from one base line to another base line and it could typically you have several issues that need to be updated to new versions and you just want to tell the the vehicle to go from one base line to another so you need some instance in the vehicle that orchestrates this in which order need does the update need to be run. And so on and this is one very important point about firmware updates in the automotive context. So now we ve reached the point of the live demo..
I hope you re really connecting to the cloud services. Now but before we do that just let me let me briefly explain what we do in this demo. We have a real ccu. This is a ccu sample board.
But this is one one of the ccu is from cm. This connects. Why i can to the list view. The system mdg.
One issue that was mentioned also before it s an engine controller from dts. So this is a true can connection. There is this connects via gsm to the to the cloud and then we have in addition to that we have a head unit here this is simulated. So that you can see it this is what the driver would see in the vehicle now so currently the software is up to date.
And what i will do now is we will assign a new update for the speaker. Which will in this case. This is of course a very simple update..
Because it would just take too long to do a full update. This would just set a new engine idle speed on this ecu. So it really rights and and a new idle speed into the ecu. This is the demonstrator.
This is our ccu here and we assign it and now hopefully. If everything works the driver would see that there s an update available. So the update run. We saw it download install and verify.
And yeah. It was successful now we have a new speed. And it s the nature of software updates that we don t see much here so nothing happened here. But you just have to believe that we really wrote a new ” .
