[poky] connman 1.33 takes very long time to start

[Flavio Suligoi]

Hi all,


I'm using Yocto "Morty" for my custom i.MX6 DualLite embedded system board, with the Freescale kernel 4.1.35.



The new "connman 1.33" takes a lot of time to start; sometime it hangs for 120 seconds and more

The cause is the poor entropy of my kernel:


[    4.659894] random: udevd urandom read with 12 bits of entropy available


If, for test, I connect an USB keyboard and, during the boot, press the keys quickly, the entropy level goes to 45 bits or more and the boot speed is normal.


Using the previous "Krogoth" version, with "connman 1.31", the boot speed was always fast, so the problem is related to the new connman version.


As workaround for this problem, now I use the "rng-tools", starting the "rngd" daemon before starting the "connmand" daemon .


Do you have any idea to solve this problem or other suggestions?


Thanks,


Flavio
