hi. I have three questions.
First, desktop environment is very slow in my BB.
when I installed mojo-ubuntu's gnome that was fast. but dabian is
very slow. even I didn't change my configuration because My mouse
point almost stop when I execute desktop menu. It really hard to
change.
I installs debian QEMU install method via debian-installer.
Is there a solution my BB debian desktop environment speed up?
Was I missing some part? When I login a Xwindow there is a error that
is "The computer clock appear to be wrong" And I click Ajust the
Clock. there is no page about Ajust Clock. I have to select ignore.
And debian desktop munu Some munu's program did not installed.
How can I fix it?

Second, Is that Native Install via debian-installer (NON QEMU based)
works proper?

I didn't fallow that section in elinux/debian because My desktop
(ubunt 8.04) didn't uncompress gzip -d initrd.gz . How can I do that?

Third, How can I use openembedded(OE) in debian-installed Beagleboard?
wiki has only angstorm tutorial. There is no ubuntu and debian OE
tuturial.
Is it passible apply OE on debian?

Thanks.
Have a nice day..

Hello,

Yes, like the wiki says, it's 'slow', debian 'armel' is compiled with
armv4t. (Angstrom is compiled with armv7). Debian Developers would
rather support more devices then one target really well. If you want
speed, use Angstrom..

Second, Is that Native Install via debian-installer (NON QEMU based)
works proper?

Yeap it does, I've tested in numerous times while writing the wiki...

I didn't fallow that section in elinux/debian because My desktop
(ubunt 8.04) didn't uncompress gzip -d initrd.gz . How can I do that?

Do you have gzip installed? "gzip --help"

Third, How can I use openembedded(OE) in debian-installed Beagleboard?

They are two completely separately maintained distros (with a kernel
compiled very similar). Each has it's own installation directions.

Forgot a note... There is no battery wired to the real time clock on
the beagleboard. So on every cold reboot, you either have to sync
the clock thru the internet. install "sudo apt-get install ntpdate' or
update the time manually with 'date' (use date --help for directions)

Thanks for your help.
But My BB installed debian is too slow. I think It is something wrong.
I execute one program my BB mouse point is move and stop and move and
stop. but CPU usage is only 30%. I think it is something wrong?
Is your installation same?

thanks Robert Nelson

Sounds about right. .:wink:

To give you some idea, when i took this image, firefox took about 2
minutes to load: (debian armv4t)

http://elinux.org/Image:Beagleboarddebian-GNOME.jpg

When i took this screen shot, (mojohandhelds "grumpy 7.10" armv5 )

The video would play, but not in full screen.. zoom into the picture
to see the 'top' values..

Right now there is no comparison for the speed of Angstrom...

Thanks.

I will take Angstorm.

Always Thanks.

That's interesting, does the difference come from FPU instructions
being enabled? Or is it really from new ARMv7 instructions?

Would an optimized libc6 for armv7 (or VFP really) make a significant
difference or is it really random applications being built with armv7
which would?

Hello,

It's way more than that. (
http://en.wikipedia.org/wiki/ARM_architecture ).. It also includes
every improvement made to the architecture since the armv4t

armv4t: ARM7TDMI (typical device ran at 60mhz)
armv5: ARM926EJ-S (typical device ran at 200mhz)
armv6:ARM1136J (typical device ran at 5XXmhz)
armv7: cortex (beagle : 5XX-6XXmhz )

Yes it does, for comparison it is possible to load every armvX variant
discussed to do a application compare.

armv4t: http://elinux.org/BeagleBoardDebian
armv5: http://elinux.org/BeagleBoardHandheldsMojo (hasty-armv5el selections)
armv6: http://elinux.org/BeagleBoardHandheldsMojo (hasty-armv6el-vfp selections)
armv7: Angstrom...

Mojo Handhelds, make a presentation at CELF 2008 that had a note about
seeing a 15-20% speedup between hasty-armv5el and hasty-armv6el-vfp
running on the beagleboard...

Hi-

I see the very same thing on ubuntu for BB. Is there currently an effort
underway by anyone to build debian/ubuntu for Cortex-A8? I thought
Canonical was doing this but the latest ubuntu built by following
http://elinux.org/BeagleBoardUbuntu is unusable.

Thanks,
Dan

I agree fully, it's gui is slower then the Mojo-Handhelds port we had
last fall. (I really hope that team gets the go ahead to continue.)

Even thou Canonical's press release said "armv7", 9.04 is built for "armv5".

On ubuntu-arm's irc log there is rumors of optimized libraries for
(vfp hardware), (not specifically cortex-a8)..

There's was also a rumor about 9.10 being "armv7" default.

Anywho, please send your comments to ubuntu, after some of my comment,
i think they know it's 'slow' gui wise.

Slow: ubuntu-desktop, xubuntu-desktop

Reasonable: lxde

I've started looking into other avenue's..

Fedora: (rpmbuild can easily change -march)
Some of my early hacking notes are listed here:
http://www.elinux.org/BeagleBoardFedora

I've also thought of creating an debian (squeeze) arm7l, any dbuild
experts out there? i do have a number of beagleboards backed by
usb-harddrives ready to be thrown at it. (they build my current
kernel deb's) Just have to setup the dbuild system...
