Hello,

What are the most common Linux distributions that are specifically designed for embedded systems?

Do the "Vendor Distributions" cost money?
Do the work only on the specific CPUs that the vendor manufactures?

I thought Linux is supposed to be Free and Open-source all around...how is it that companies charge money for it ?
I'm not too familiar with the subject, can you explain a little more...

I think the 2 versions that you mentioned aren't true Linux.
It's what's called a microkernel...while true Linux is considered to be a "Monolithic Kernel"

A simple Google search reveals the difference:

I don't have specific examples in mind for embedded real time platforms, but for desktop environments for example, Red Hat Enterprise is not free. You tend to pay for official technical support I believe.
