The explanation is very good and straight to the points that are really useful when you're working on a real-time project.

The content is quite good, but the lecture style is quite exhausting. The trainer repeats himself again and again.

This 4-part series teaches Yocto comprehensively, in focused bite-sized pieces (very helpful if you want to get straight to specific Yocto topics). Trainer knows his Yocto in and out !!!

Gobbledygook. All over the place. This file is in this folder and then here and jump here and you edit there. No idea what's going on. Impossible to follow logically. Don't care for the poor English either. No structure to follow.

The only difficult part about this course is the poor quality of the author's audio. It seems as though he used the external (ie; ambient) microphone on a laptop to record this video. Therefore there's quite a bit of "splatter" to his audio, and thus you must keep the audio volume level down as low as possible in order to minimize the splatter (distortion). Thus it's a challenge to follow along with what he's talking about in several areas--especially when coupled with his accent, and with the speed at which he talks. I quite enjoyed his accent, but it does compound the issues of poor audio quality due to a sub-optimal audio recording device. For such an important course(s) as this one on Yocto (including all 4 parts), he should really be using a close-microphone technique to record his discussion. It's unfortunate that he did not do so, because the material is really very important...and he certainly has valuable expertise to share with those working through the course(s).

Everything explained perfectly for me. Some videos were repetitive however it helped me to remember the things permanently

Thorough. I especially liked the "make a mistake, look under the covers to see why it went wrong" approach.

This is the most sold and rated course because is almost the only one. Explanation is not good. This course repeats a LOT from the first part and it has the same issues: It goes over and over irrelevant stuff and improvising. It is not a solid course to understand the framework. I am going to skip buying part 3 and 4 for sure.

Served my requirement in the project. I can use the concepts learnt here to understand the layout of recipes in my project.

Good course. 1) Pause just before hitting return so I can see what you typed. 2) Try miking better to be less muffled. 3) More standard English would be helpful. The content was very good and suitable for someone familiar with Yocto Build System

So far good. I'm sure to come back and review again as I'm not familiar/not have extensive experience of yocto, but having gone thru course so far I know or remember (hopefully) where particular topic and concept is discussed. Thanks for putting it together and making it available.

This was really helpful in making the leap from just using Yocto to build pre-made images, to actually being able to synthesize recipes and make custom images. The course does a good job of also explaining some of the lower level things that are happening which is super helpful when inevitably I will have to debug something.

Fundamentals on yocto is very good . IS there any course related to bootloader and kernel customization using yocto ? Like: 1.What modifications need to do for new custom board in bootloader stage and kernel stage 2.What Modification need to do in board file and device tree file to bring up.
