I have an embedded device running a linux environment built with Yocto. I have both openssh-server and nginx running, both of which take 1 minute to start because they are waiting on enough entropy:
From dmesg: 56.338824] random: crng init done
uname: Linux beaglebone 5.0.12-jumpnow #1 Wed Sep 25 22:09:50 UTC 2019 armv7l GNU/Linux
Is there any way I can speed up this process? Perhaps cache some entropy between reboots? There is no mouse or keyboard, and may be very little to no network traffic for faster entropy generation.
