good morning devs,
i wanted to dev some crypto stuff last nigth and therefore my first focus on rng
stuff. to make it short,
i dont get any random numbers out ... the rng test from tests dir simply returns
zeros. I want make sure
its not a problem between mouse and keyboard :) sooo can anyone tell me if this
is a bug:
ps. sorry for spaming this code here - I am still a little bit unexp with riot -
and did not want to open git issue req yet.
pps. for me it seems that the ->POWER call does not work. and POWER is the only
RNG offset I can not "calculate" or
verify (do not find it all) in the "nrf51 seriees ref manual". hhHelp
ppps. _poweron/_poweroff calls of course deliver same result.
thanks and have a great day
Jan
