Hi Detlev and Wolfgang, Thanks for your comments. I understand a little bit of healthy inertia and do appreciate the constraints. I believe I have covered this ground very thoroughly and would like advice please on what to do next. The options I can see are: - change the code to use a fallback when a microsecond timer is not available - integrate with boot progress - something else? drop it? Regards.
