Thanks for your answer. With that, if you desire it, I can try to help you lowering the boot time at least in light of the Jitter RNG. This, however, requires a bit of analysis which you need to help me with as I do not have a board you discuss. But the Jitter RNG has some turning knobs that can be used. Ciao Stephan
