HOB is deprecated, now the tool is called Toaster.

Regarding the book, now there is another one from Alex González [1]
also being sold by Amazon and Packt. Read the descriptions and the
reviews and decide what is suitable for you.

Start using the kernel provided by Embest. If they have a BSP this
would be an starting point as mars board is not supported by FSL
Community BSP 1.8 [2]

I've heard mars is very close to riot, and riot is supported by FSL
Community BSP 1.8. Maybe this could be a nice second step.

Take a look on the suggested how-to install the BSP on warp board here
[3], in fact you decide if you want to use mfg-tools or other tool.

CORE_IMAGE_EXTRA_INSTALL += "opencv" maybe? I have never worked
directly with openCV, maybe [4] can help
