Hello Everybody,
I need to reduce the Booting time of my Beaglebone Black (4.14.71-ti-r80) but I also need a lot of drivers like SPI, I2C, and Remoteproc for the PRUs.
By now it boots within ca. 1:30 which is way to much. Is there a simple way or a good guide to lower this time?
Regards Chris
First, upgrade from that image..

There was a lot of tweaks over the last year to get the boot time
down.. (first boot always sucks, as ssh key's are regenerated..)

Hi Chris!
Everybody needs to reduce boot time But it’s increasing with every new kernel version.
I just set up a system on BBB with wifi dongle:
$ uname -r 4.14.146-bone29 $ systemd-analyze time Startup finished in 1.179s (kernel) + 18.086s (userspace) = 19.265s
But uio_pruss instead of rprog, no config-pin. The -ti kernel is ~ 10 s slower.
Regards
Rember, the -ti kernel has smp/am57xx support.. So it's unfair, as the
-bone kernel gets to be much simpler.. ( lack of smp.. )

Who needs am57xx support for the BBB?
