Thank you for all the replies.
Yes, the DSTREAM is a hardware debugger / probe from ARM.
The DS-5 is the Eclipse-based software front end / IDE for software
development and debugging, also an ARM product, and requires
a license.
Yes, I spoke with Aspeed and they said that they don't DSTREAM or
DS-5, they use BDI hardware debuggers.
I will review QEMU and see if that can add value to what I'm trying
to accomplish with software development and testing.
Thanks, Dave

I've used it on quite a few platforms. Can be very handy for bugs and performance profiling.
You should be able to create the config yourself, at least for a basic setup. If the device has CoreSight then much of it should be automatic.
