If that's what you think, then it's time for you to become enlightened,
Dmitry. :-)

Start here:

When people come to comp.lang.ada and talk about wanting to learn Ada and
get it running in a bare metal environment, then quite often they are
talking about these types of boards, not the safety critical ones with
a price tag to match.

Not everyone needs the industrial type boards you obviously need during
your work, and there is a _vast_ embedded world of which your industrial
type environment is only a small part.

There's nothing to stop a end user programmer writing their own BSP; this
appears to be a common capability for RTOS environments. I've written 2-3
BSPs for RTEMS over the years.
