Thank you very much, Bruce.
One more on this, if I may.
We actually need the toolchain for windows, and I think SDK is for Linux only.
Is there some toolchain which should be appropriate for target ?
Should I check if minGW toolchain should match ? I think there are
serveral gcc versions, so I'm not sure how to find matching.

Thank you!
