Course 2 of 6 in the Specialization Internet of Things

Do you want to develop skills to prototype embedded products using state-of-the-art technologies? In this course you will build a hardware and software development environment to guide your journey through the Internet of Things specialization courses. We will use the DragonBoard™ 410c single board computer (SBC). This is the first in a series of courses where you will learn both the theory and get the hands-on development practice needed to prototype Internet of Things products. This course is suitable for a broad range of learners. This course is for you if: - You want to learn how to use learn how to use Linux for embedded purposes. - You want to pivot your career towards the design and development of Internet of Things enabled products - You are an entrepreneur, innovator or member of a DIY community Learning Goals: After completing this course, you will be able to: 1) Know where you can find resources and help in the 96Boards ecosystem. 2) Describe the DragonBoard™ 410c peripherals, I/O expansion capabilities, Compute (CPU and Graphics) capabilities, and Connectivity capabilities. 3) Understand how to navigate and make use of the Linux terminal. 4) Configure at least one integrated development environment (IDE) for developing software. 5) Make use of Git and GitHub for version control purposes. 6) Create and build projects that interface with sensors and actuators through GPIO and Arduino.

Changing your Operating System (Supplemental / Optional)

The DragonBoard™ 410c is capable of running a variety of different operating systems, that being said you are free to chose the operating system that you find is best fit for you. Now, we understand that there is a diverse user base for this board and would like to cover as much as possible in this lesson so everyone can enjoy it! Whether you are a Windows user or a Mac user, or prefer Android over Ubuntu, there is a video or two here for you! In this lesson we will help you choose an operating system to best fit for your needs, we will then cover the download, flashing and installation process for all currently available operating systems. Because of the diverse nature of this board we will teach you multiple ways to flash your new operating system and provide a pro's and con's list for the different methods. By the end of this lesson switching between operating system will be easy and exciting for users of all skill levels.

At this point in the lesson, we've already taken you to the website, 96boads.org.

We've showed you how to download the proper files that you need,

the bootloader, the binaries, all the images.

We then walked you through creating a path variable to

the fastboot location in your SDK.

>> Yeah. >> You've already done all this before but

we just wanted to walk you through it one more time.

Now it's time to boot the board into fast boot and get the image onto the board.

>> Yeah >> Let's take a look over here and

first of all it's important to make sure it's not powered on right.

But what we are also going to make sure of is that it's in the right boot

configuration, and that's making sure it is 0000.

That's four times right?

>> Yeah. >> 00, all right.

[LAUGH] >> All of these switches should be set at

0 on the back, yeah.

>> Yeah. [COUGH] Excellent.

So now that we have all that set up and we have our keyboard and mouse hooked in and

our micro USB plugged in, our HDMI plugged in, we are set to boot it up.

>> Yep. >> But, from what you learned in

a previous lesson,

we need to make sure that we hold our finger on the little minus button here.

>> Located next to the USB ports there.

>> Yeah that's going to ensure that we boot it into fast boot.

And then we're going to power it on.

So power it on.

Now we've noticed the sweet spot to get it into fast boot is not to hold it on for

too long, ten seconds is about right.

>> Yeah. >> So by the end of this sentence

I'm gonna let it go.

All right, there we go.

>> So now the board should be in fast boot.

And the best way to check if it's in fast boot is go back into your terminal, and

remember the path variable that you created before, so

now we're gonna use that path variable.

We're just gonna type in %fastboot% devices.

Boom you get a little code there and that code is for the DragonBoard, and

it's telling me that the DragonBoard is in the fast boot mode.

So now we're ready to start flashing stuff on there.

>> And essentially, just to reiterate as many times as possible, when he's doing

this fast boot command, the path variable- >> What he set it as,

if you remember, was the fast boot executable.

>> Yeah. >> So, whats happening is,

is he's essentially performing the fast boot executable and

then calling the device command.

So he's using the device command with the fast boot executable.

>> Yeah it's a good thing you touched on that.

>> Yeah.

>> So now it's time to take a look back at

that script we were looking at last time, right?

>> Yes. So,

if you remember in the previous video, we modified a script called flash all file.

And so we put percentage signs around all the fastboots.

And here's a very important note to keep in mind,

you wanna save the file as flashall.bat.

You want to slave it as a flashall.bat.

That's the correct extension to actually use that file.

To use that script.

So we're going to click yes.

And now the file is in to correct format, so we're ready to go.

So now what we're gonna do is go straight to the file that we downloaded the boot

loader, the boot image, the root fs image, we're gonna go into that folder here.

So let's see, users, going to go to Desktop,

in that, there's another folder called linaro.

There we go.

And if you see here, we have all of the files Satyung downloaded before,

all unzipped and ready to go.

>> Including the flashall.bat.

>> Yep, and so what we're going to do,

is we're just going to simply type in the name of that file there.

>> That's going to execute it, basically.

And what you see on the screen there is,

it's performing each individual one of those flashes for us.

And if we didn't have that script, we would have had to do that one by one.

>> Yeah, yeah.

>> Which is kind of a pain in the butt.

>> So now it's all ready to go and the boot loader is now on the DragonBoard.

Now if you remember we also downloaded two other files, the boot image file and then

the ALIP root FS image file, the graphical interface for the root file system.

So what we're gonna do is use that same path label there,

fast boot, we're going to type in flash boot.

And then we're going to type in the name of that boot image file, so it's going to

say boot-linaro-vivid, Hawking standard, snapdragon, and we're going to click OK.

And this is going to boot the image file onto the DragonBoard,

It's already done, and now we're gonna go here.

Next we gonna download the rootfs system.

So here we go, flash rootfs, and we're gonna have another file.

>> Starts with linaro.

>> Starts with linaro there, yep, thank you.

What you want to make sure about this file is, and I think Muchresh touched on it,

but, is that it's in ALIP.

So, ALIP and you can see this, I think I mentioned this in the last video, but

ALIP you can read more about it in the release notes under the Ubuntu

download link, on the 96 boards downloads page, for

the DragonBoard 410C >> Yeah, there you go

>> But yeah, anyways,

that's the file you want to do if you want the desktop version of the Ubuntu.

>> Yeah, so we are going to play enter there, and

its going to start downloading it.

And there you go, so once that finishes downloading you now have

the root file system on your DragonBoard, the boot image file on your DragonBoard,

you have the boot loader, you have everything on your DragonBoard.

And the DragonBoard now has a Lenora operating system on it.

>> Yeah. >> You can just plug out the Micro USB and

reboot it on to the Lenora operating system.

>> Yeah. What's usually recommended is,

don't worry about how you boot this down.

Well I mean, right now it's finishing writing the files.

But you can just unplug it, unplug the micro USB like Uker said and

then just plug it back in.

It should boot right into your Ubuntu.

>> Yep, there you go.

>> All right, we'll see you in later- >> Videos

>> Later videos [LAUGH]
