As the subject says, I would like to shrink the boot time below 3 seconds. I've seen all kinds of YouTube videos, read through the SwiftBeagle site, but still have some questions. First of all, I am currently at an 8 second boot, after disabling GateOne, Cloud9 and Bone101.
Here is the hardware I need:
1. LCD7 cape
2. USB
3. GPIO
4. CAN Bus
Now where do I begin? As far as optimizing u-boot, I know that I can change the boot delay from 1 to 0 to gain a second. Anything else in u-boot that I can do?
I know that I can remove a lot of the stuff that's not needed in the kernel, but the kernel confuses me. There are so many options in the menuconfig that I don't know what half of them do.
I'm noticing that it takes 3 seconds to do a recovery of the EXT4-fs (see below). Is there a way to optimize this?

Koen,
I have not tried bootchart... I did watch your video on YouTube about a 1 second boot... very interesting, but I didn't quite understand everything... I have a lot to learn yet!
So is the best place to pass arguments to the kernel in the uEnv.txt file?

I trimmed a little more from the kernel and used the minimal rootfs from Angstrom-Distribution.org and it now takes 3 seconds from the kernel being uncompressed to the login. HOWEVER, u-boot takes about 3-4 seconds, so this needs to be optimized. Any suggestions on where to start with this? It seems that someone would have reduced the u-boot boot time to pretty much nothing by now... anyone care to share what they did or post their source?

For the fastest possible boot, you'd likely want to compile your bootargs into u-boot and not read uenv.txt.

ELinux.org has some resources for serial logging. It might be good if you shared your timed logs. The file system has been seen to be a bottleneck in the past.

Newer u-boot sources have improved the ext3/4 load from mmc times, make

sure you're using those sources. I believe Koen saw extload times
reduce to around 20% of the unpatched times (sorry, from memory, no
link).
You can also get a faster SD card, that will reduce access times for
file system reads and kernel load from mmc.
Increase your serial port speed to 1Mbps or higher, the 115200 default
speed can add time to your boot if there's much printed by the kernel.
Quiet bootarg can help here, too.
You could build an uncompressed kernel, if you're currently not, if
kernel decompression is really taking much time. But gauge this
tradeoff with the extload duration to see if it's worth it.
Don't enable a serial port console. I believe there's about half a
second during kernel start dedicated to putting a console on the tty
(although I'm not sure exactly what happens during that time...).

Well, what is the best way to measure uBoot? I ran the bootchart and it's over 3 seconds until things start happening, so I'm making the assumption that u-boot takes that long to load...
See the attached file from bootchart. It's a little blurry because I can only upload 2000x2000 images. If you want I can email you the .svg file.

there was a prior email saying loading time was improved. did you see that
SD card speed and loading kernel were factors addressed.
claims of 20x improvement were promised (-:
as far as your other question about splash screen faster I dont have interest or knowledge
sound like a waste of time but I dont know your erquirements
what in the world is a boot chart? some sw trace tool run on source???

Here is what I get from grabserial... I know there is a 1 second delay that can be changed to 0, but I'm still not happy with u-boot. As someone suggested, I'll try building all kernel arguments into u-boot instead of using uEnv.txt and see if that helps much.

first character on the serial port. That'll give you a full bootup
timing view, rather than resetting the counter when the kernel goes.
It'll look like my Debian Grabserial log [1]. No counter resetting.

the SPL code and fix that, then, BAM half second faster boot. :)
Granted, I have no idea what's happening there, but I assume DDR and
mmc setup are needed. Probably some clock setup, too.
But, if you find things like USB or Ethernet in there, rip them out if
you don't need them and care about boot time.

that part from the u-boot code (which should be doable).

Say someone new to BB/Linux wanted to achieve these faster boots.
Is there any tutorial written that people know of?

to BeagleBoard
Hi Brent,
i am new to linux and beaglebone ,I would like to decrease the boot time below 5 seconds
Here is the hardware I need:
1. LCD7 cape
2.buzzer cape
2. USB
3. GPIO
some services are disabled apache2,connman,avahi,cups then also it is taking 38sec please tell me how to decrease and what are the places
whatever booting i captured in grabseral pasted bellow and what are the services contains please tell me what are the service i can disable also
hopefully i am waiting for your repay and i am not able to change os also because this os is customer given
