Could you also update the documentation pages to reflect the actual memory map 
for the Arm devices? It took me some time and experimentation to find this for 
my tests.

Sounds ok.

7.0.0

I have a template project that can generate several binaries intended to run on 
QEMU:

- https://github.com/micro-os-plus/hello-world-qemu-template-xpack/

The only prerequisite is npm/xpm, the rest of the dependencies are handled 
automatically.

If this does not work for you, please tell me exactly which binary you need, 
and I can try to generate it.


Thank you,
