Yocto Linux Primer 2017

[@jarekb2043]

Best explanation of Yocto/embedded linux I've seen so far... Highly recommended!

[@40Yant]

great intro to Yocto!

[@vijayesd]

Detailed explanation... Thank you for uploading.

[@johnnynguyen149]

Wonderful presentation

[@Hushui110]

Where could I download the presentation PPT/pdf ? Thanks

[@uhmgawa1435]

Where might one find the presentation slides?

[@surjithsundaresan9175]

helpful explanation sir , thanks

[@johnnyrobotfpv7104]

I have a connectcore 6 with the development kit. (no monitor) I ran through the firmware update procedure, compiled digi-embedded-yocto and deployed. Unfortunately, it still boots to Busybox (firmware?). I'm totally lost at this point. There's a huge learning curve here.

[@TradeWithJon]

Are we able to purchase the Digi Connect Core?

You're a gentleman and a scholar, thank you!

[@rubenscarrillo]

Very useful presentation. Thank you

Awesome explanation, really helpful

Excellent, really helpful

Anyone has an idea how to actually use Yocto? i.e. how to use the linux drivers to create actual applications using C for example? All videos just talk talk talk and go on about how great Yocto is and how to set it up and use bitbake commands, but no one shows how to actually use it to create actual useful applications. I have yet to see a blinking LED example using Yocto, let alone complex drivers like RTOS API, Ethernet/WIFI libraries or cryptographic library. Please help!

[@GaneshMohanNelliparambil]

The meta layer from the silicon vendor typically includes recipes for the drivers as well. Then if you want to use a gpio for example, you can use the menuconfig and enable the respective driver and build your kernel. And then the method for using a pin for blinking led is same for all linux distribution s. For accessing gpios from user space, mount sysfs, export pins, set direction, write value.

yocto is a BUILD system, it's similar to make, except for an entire linux system. Changing actual software is at a totally different level.

[@Galal0110]

@@robbietorkelsonn8509 Ok, so what level is that and do you know what I should search for to achieve such a basic idea with Yocto?

[@robbietorkelsonn8509]

@@Galal0110 Yocto is a build system for creating a custom linux distribution. It's realy intended for teams. You are better off with buildroot to learn what it does, it does the same thing, namely creating a linux distribution for embedded systems. If you want to create software for linux, there are basically four parts you can learn. - The kernel and device drivers - User layer applications - graphical applications - most programming frameworks now work in linux too (for example python, .NET through mono, java, ...) In order to learn kernel and device drivers, here is a good text free online: lwn.net/Kernel/LDD3/ This seems to be a good recent book that seems to be very practical and up to date: www.amazon.com/Linux-Driver-Development-Embedded-Processors/dp/1729321828 Now available on kindle for 9$ For learning user layer applications there is a good book available: www.amazon.com/Linux-Programming-Interface-System-Handbook-ebook/dp/B004OEJMZM/ref=sr_1_1?dchild=1&keywords=The+Linux+Programming+Interface&qid=1587928719&s=books&sr=1-1 If you search for it on google you might find the pdf. Graphical applications, mostly QT 5, there are many resources, you can choose between C and python

Nice job!

RBL similar to ROM-BIOS SPL/MLO similar to MBR loader u-boot similar to MSDOS loading linux similar to loadlin

[@optimalsupreme5080]

pfft this is what I hate ..oh revolution this or that ..new idea embedded system..All was done better on, and with the Classic Amiga hardware/OS . The Amiga still cant be beat in any area.This the funny part or rather sad part. Linux was invented on an Amiga in 1988.

[@heyheyhophop]

Could you elaborate? Would be interesting to hear or get some references / links.

[@Aduskett]

Recommending Ubuntu? Most shameful!

[@swagatnayak9146]

Why?

[@Aduskett]

ubuntu is broken the moment you enable universe/multiverse. the non-canonical repos are a shitshow of unpatched and/or hilariously broken "community" packages that replace debian packages at random. of course, all the software people actually want to use is in those known-bad repos result: as a ubuntu user, your system is riddled with security holes and breakage from day one.

[@Aduskett]

Oh yeah, I almost forgot: universe/multiverse are enabled by default Ubuntu is broken and unsupportable out of the box

[@jimcervantes5659]

Works perfectly fine as a host system for yocto. Just fire up a vm and your done. Where's the shame in that?

[@TP-kq9ul]

@@jimcervantes5659 Using Yocto on a VM is a bad idea because it is 2-3 times slower than native Linux machine. And yes, use Debian. Better than Ubuntu.
