Hi Jan,

This is missing a step: Build a different image configuration, e.g.
switching to the RT kernel. Otherwise, you are now suggesting to flash the same SWU on the disk as you write as > full image, and we know that this is broken (plus we have no error detection for that yet).

I have mentioned a reference section "building-and-testing-the-cip-core-image" in the readme for BBB, which means we have to create two images (Non-RT and RT) as per the section.

I will clearly mention in BBB section to create two images.

Thanks & Regards
Shivanand K

Most of the steps are similar for both qemu-amd64 and BBB targets.
Add reference link wherever required instead of repeating steps.
