“Excellent overview of Yocto/Open-embedded, with a good level of detail.”  Mar 2020

“I did come away with a somewhat better understanding of the Yocto environment.”  Mar 2020

“Very thorough introduction to the fundamentals of Yocto, helped me to clarify some of the assumptions I’ve made in the past, and I learned a few new tricks to help me get my work done quicker.”  Mar 2020

“As someone who has been using Yocto for a long time without any training in it, it answered a lot of “why”s, as I had been doing something without
really understanding why I was doing it that way or what the alternatives were.”  Mar 2020
