Introduction to Embedded Linux Part 1 - Buildroot | Digi-Key Electronics
Переглядів 314,761
День томуLinux is a powerful operating system that can be compiled for a number of platforms and architectures. One of the biggest draws is its ability to be customized for an application. Tools like Buildroot, OpenWRT, and Yocto Project help us create custom Linux distributions for embedded systems.
In this video series, we will explore Buildroot and the Yocto Project. We also demonstrate how you might develop applications for embedded Linux. We will not dive into the specifics of how each of these systems work but give you a good starting place so you can read or watch more advanced material about working with embedded Linux.
See this written tutorial if you would like to review the commands issued in this tutorial for Buildroot: www.digikey.com/en/maker/proj...
To start, we provide some reasons and examples as to why you might want to use embedded Linux over other platforms, such as bare-metal programming on microcontrollers and an RTOS. Often, your application will dictate the use of one platform over another. Embedded Linux offers the ability to reuse high-level code written and tested by others that work across a variety of platforms. This can save you development time when you need things like networking, graphics, cryptography, audio, machine learning, etc.
We introduce Buildroot as one of the easiest tools to use for creating a custom Linux image. We demonstrate it by creating a Linux distribution for the STM32MP157D-DK1 single board computer. From there, we flash the distribution image onto an SD card and load Linux on the board, which allows us to log in with a serial terminal to do basic file manipulation and script writing.

The introduction is great. I have worked with buildroot on and off for years. You can split the build into components, boot loaders, kernel, device-tree, root filesystem. This makes updating the kernel easy as long as you can just update each part on your SD card. You can make these components from the buildroot build command line. The best way to figure this out is 'make help' in the buildroot directory, there is a lot of information there. Hope I have not just taken the subject of an up and coming episode of this series. Keep up the good work I will be able to point co-works at this series instead of writing lots of documentation.

I've been working with Yocto on and off for a couple of years. It is extremely powerful. Just finished a custom build for a client using i.MX6 ULL chip. Never would have been able to do it without yocto. Looking forward to the series. I still have a lot to learn, I think my work flow needs improving. I've notice over the last three years the need for developers to be using Linux to sky rocket. I'm coming into contact with companies where only the admin staff are on Windows. Management on Mac. Everyone else on Linux.

Correction: We do not have to completely rebuild the entire image in buildroot when we make any changes. We can avoid distclean and buildroot build system will automatically detect which changes are made and it will only build those packages where you make the changes.

Hello Shawn and Digi-Key! Thanks for the amazing introduction to Embedded Linux and Buildroot! how to use gcc on the generated embedded linux image. because when i use pip to install python frameworks, i get a compile error, the system always works with the cross compiler that generated the linux image
@ShawnHymel 2 роки тому
Good question! From what I've gathered, you can't use Buildroot to include a compiler on the target (buildroot.org/downloads/manual/manual.html#faq-no-compiler-on-target). You can use another system (e.g. Yocto) to add such packages. In a future episode, I plan to show you how can cross-compile on your host machine to include a custom application in the target image.
@JonitoFischer 2 роки тому
You can do motor control using FreeRTOS for instance, just use kernel unaware interrupts for time critical interrupts that do the control work and the rest can be easily handled by OS threads. The price you pay is less time for OS tasks...

I'm definitely an openwrt fanboy. Routers are easy to come by (since no-one is happy with their 100Mb gear anymore) and have all the resources to be used as IoT controllers. And they are quite secure as openwrt is built with security in mind.

Make sure you run the "sync" command after you run "dd" like that to be sure all the writes are actually flushed to the sd card before you remove it.

From what I understand, umount will do a sync before unmounting the drive. So long as I do a `umount` or `sync`, I should be good.

Hi, why is strict timing mentioned in baremetal when a RTOS is always mentioned for deterministic behaviour?
@ShawnHymel 2 роки тому
Great question! Most RTOSes can be made to be deterministic or non-deterministic, depending on how you configure the scheduler and heap allocation. As a result, your application is not guaranteed to be completely deterministic just because you use an RTOS (although, with the right settings, you can make it so). I might not have described it correctly in the video...but my thoughts for "strict timing" for baremetal include things like needing to sample a sensor every 200 microseconds. A time slice in most RTOSes is 1-10ms, so an RTOS won't help you meet that timing requirement. You can combine baremetal techniques and an RTOS (e.g. use a hardware timer to set up a sampling schedule and feed the data to a FIFO that's read by an RTOS task).

Excellent I've been learning python for 2 years now. Was wondering if Linux would be useful in conjunction with python. I don't particularly care raspberry pi because of the amount of current it uses. Can't really do a stand alone project with it. But I'm glad brought up another board to use which is probably less of a energy hog. Really cool that SpaceX uses Linux to run the rockets
@canwenot573 2 роки тому
In my opinion, Linux and Python are two peas in a pod. Even if you're not too interested in Raspberry Pi; Linux itself, as pointed out in the video, is a very popular and powerful operating system. Learning how to use Linux isn't too difficult if you're already familiar with systems like Windows or MacOS. There is also a massive community of developers and users to support you in your pursuits. Python and Linux are both very useful in terms of embedded systems. SBC's and other small standalone electronics can be hard to develop for, especially if the hardware or applications are custom. This video series should elaborate more on the challenges of programming on embedded devices, but suffice it to say that having a good working knowledge of Linux is very handy if you're looking to program embedded devices yourself. I hope that helps.

Great overview! I needed this to see what I want to do with my Raspberry Pi. BTW, _router_ (a device that _routes_ packets) is pronounced identically to "rooter" because _route_ is pronounced identically to "root". A _router_ (a device that _routs_ things) would be a device that creates grooves in wood or metal, since the word there is _rout._

@izik5 2 роки тому
Most likely a business decision long ago, it allowed them to share the same code base with the offline software (which is only available for Windows). Personally I would love to see them switch to a linux based console with offline software ported to macOS. That would be such a massive rewrite that they aren’t likely to go that route unless some external factor forced their hand.
