There is talk about that you need either a real target (in an example
that's some abstract ARM evolution board) or the synthetic linux target
which can "emulate" the real one on the _linux_ hosts only.

Hence two ways are exists. Either to have a real target (=board) which
is supported by eCos or install Linux. If you are advanced user and
familiar with Linux and GNU you can install some kind of Virtual Machine
and eCos for Linux on the guest OS (Linux) to play with it having no
real hardware. But, this is an off-topic for the discuss-list, however,
you can find the answers in the list's history.
