Not really, I just banged my head against the brick wall for a long time.
As far as app/kernel code in NUT, everything should run in SYS mode period.
Forget 100% about using user mode until you want to introduce *TRUE*
divided territory - ie: User Land and Kernel Land - *AND* really build
two different applications - the kernel as an image, and the user
applications as an image. Truth is, NUT runs on *SMALL* platforms,
where that added cost in flash space is just large.
