Thx Robert for your answer, I did what you say but it did not change the
boot time.

if the version I'm using is the problem, what version should I use?

Thx in advance.

Oh.. why are you running the TIDL image on an AM335x, it's got so many
packages only for AM57xx devices..

Just go under:

cd /opt/scripts/

Run "git pull"

Then reboot, most of the am57xx boot stuff will be disabled on the
next bootup.. cmem/tipc/etc..

Hello Tarmo,

you were right I just disabled the snap package and I earned 22 sec, thanks
for your help.

At the same time, I've realized that I don't need such a modern kernel, so
I decided to test with a more "stable" one.

But as you can see the problem is still present, the userspace boot time
takes too much time.

so if it's not the kernel version ... how can I do better times?

I haven't seen those dev-loop devices before (perhaps they come with kernel 
5.4). They look rather suspicious with the 50 second duration. Have a look 
at what their logs say, e.g.:

$ journalctl -u dev-loop0

The snap package system is a bit of a resource hog and it primarily serves 
as a convenience for some minority use cases. Are you sure you need it on a 
BBB?
Final thought - maybe your SD card simply has poor performance? I doubt 
it'll make a significant difference, but you can try flashing your image 
into eMMC or using a higher-end SD card.
