Point is that writing eCos applications is relatively easy task
comparing to low-level porting.
Any student can use eCos native Linux synthetic target
(http://ecos.sourceware.org/ecos/boards/linuxsynth.html) and write
eCos application for PC.

However, when you want to study kernel internals, to change boot code
and HAL, to do low-level system programming you are obliged to have
real hardware. And that sucks with eCos - because there are no good
emulators nor simulators for the worlds most popular architectures
like ARM or MIPS.

You take UBoot, Linux or any other bigger similar project - works out
of the box with qemu-system-XXX, and it is a pleasure and a joy to
learn. It would be great if we could have something like this with
