Hi everyone. Newbee question here.
I compiled Kernel 4.14 on the BBB (latest currently) following the buildroot recipe.
I used BB.org as linux defconfig and am335x_evm as uboot defconfig.
The board boots in roughly 5 seconds from my SD card. Great.
Now i added open_ssh to get ssh and sftp functionality, it works but now my board hands for 185 seconds at each boot:
[ 6.120766] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
[ 191.444192] random: crng init done
Welcome to Buildroot
So i considered maybe it was re-generating its SSH keys at each boot because maybe they did not persist, but after safely remove my SD from the system, i confirmed they do persist under etc/ssh.
So i went to the /etc/init.d/ and edited the S50sshd script, and commented out the command that generate the keys (supposingly only if missing)
Unfortunatly, this did not help either.
Finally i temporarily MOVED the script one laye lower, and it did the trick, no more delay. But of course i loose my ssh/sftp functionalities
Sooooo… What is the problem ? I read somewhere that there was a bug introduced in kernel 4.16 about the crng init that was not returning the right status but this is kernel 4.14 so this must be something else.
Thanx for any help.
