In preparation of the Tech Tips AMA on Yocto, this is a place to post the questions you want me to look into (yes – I’m cheating in wanting to give myself some time to research and test the answers before I go live!).

To start people off, here are some of the questions I have been asked outside of this channel that I _may_ be answering:

– What is with all these strange names for Yocto relases – Kirkstone, Scarthgap, etc?
– I have built an image and installed it on my target. Can I add more things to it without having to to-flash the entire board?
– I have inherited a system from someone else. I found that I had to change a file on the board to make some changes. I have searched through all the recipes but cannot see where the original file is for me to make the changes in the build.
– I need to change some of the configuration parameters of the kernel, how do I do it?
– I am getting errors when I am building a recipe. How can I debug it?
– How can I specify the partitions of the SD card image that gets built by Yocto?
– I added OpenCV to my system, but I am getting `AttributeError: module ‘cv2’ has no attribute ‘dnn’` when I try to run my code.

Reply to this post with the Yocto questions and issues you have got and I will see what I can do to answer them.

You can also keep me on my toes and ask questions in the live chat – but there is always the danger that I will respond with, “Great Question – let me get back to you on that”!
