Debian / Installing From Cf

« on: May 14, 2008, 02:30:22 am »

There really isn't any reason you *can't* run from CF...if you install Altboot on your pdaxrom and if you put a Debian rootfs on a CF card, you should be able to pivot_root into the CF card and boot from it normally.

Debian / Why Is Debian Slow?

« on: May 14, 2008, 02:27:22 am »

The SD card reader on the C-series is a serious bottleneck in my experience.  The internal flash is faster, giving Angstrom et. al. the appearance of being faster.  Also, with Debian, programs are bigger (as mentioned above, they are more featureful), so loading/unloading data from storage will naturally take longer anyway.  However, in my experience, EABI programs in Debian run about as fast as their Angstrom counterparts once loaded into RAM.

If you are using a GUI, by far the biggest bottleneck with responsiveness is anti-aliasing.  If you can turn it off (if your GUI even supports it), you will notice a HUGE speed boost.  In fact, with XFCE on my Debian zaurus, the difference in speed before and after is about an order of magnitude.

Debian / [done] Use Debian Official Xorg And Tslib!

X.org is a lot more bloated than Xfbdev...do you notice it at all?

Debian / Compiling Eabi Kernel

On Debian, you'll need scratchbox and an ARM5 toochain.  See www.scratchbox.org for details.

Debian / [new] Kernel 2.6.24.4 With Cpufreq

« on: February 06, 2008, 12:30:34 am »

I tried to kexec -f the image on a C1000; the device froze.  Normal kexec causes it to boot the original kernel (2.6.23).  Any suggestions?

Debian / Question - Make Bootable Image Of Tiny Linux

« on: December 31, 2007, 12:44:08 am »

I think it's theoretically possible, but the software for that distro seems...dated (2005-ish).  I think you could install OpenZaurus or Angstrom or Debian and get the same software packages (or equivalent replacements--I'm not sure any of them still have Netscape as a package, for example ).  Angstrom is close to producing a stable release, and its default install is pretty small (~20 MB?) if you get the console image.

Personally, I run Debian EABI off of a 4 GB SDHC card, but I boot Angstrom on internal Flash as a backup.

Debian / Sdhc In Debian

« on: December 11, 2007, 05:28:13 pm »

I've been booting my C1000 with Debian EABI off of a Lexar 4GB SDHC card for about a week now...the latest Angstrom kernels recognize it without problems.

Debian / U-boot Vs Sharp Bootloaders

« on: December 11, 2007, 03:33:57 pm »

you don't need uboot for that: http://linuxtogo.org/gowiki/AngstromAndCacko

That's exactly what I needed to do.  Many thanks!

Debian / U-boot Vs Sharp Bootloaders

« on: December 11, 2007, 12:28:41 am »

Hello,

I'm currently running Debian EABI on my C1000 from a 4gb SDHC card with some success, but I'm using Sharp's original bootloader with Angstrom's 10302007 kernel and modules.  I've heard that U-Boot is supposed to be "better," but I've never heard how.  Are there advantages to using U-Boot over Sharp's traditional bootloader?  Is it true that with U-Boot, I don't have to continuously re-flash the ROM to update the kernel (i.e. with U-Boot, can I boot into a kernel on an SD card?)

Thanks in advance.

Debian / Brightness Control

« on: November 25, 2007, 09:31:56 pm »

I think everything *except* gpe-conf and bl can be found in the feeds at the moment.  Snarfing gpe-conf from Angstrom and getting the GPE support libraries from the feeds worked for me (as well as snarfing Angstrom's bl script in /usr/bin, which really does nothing more than invokes gpe-conf).

Debian / Twitchy Or Jump Mouse?

« on: November 25, 2007, 04:59:30 pm »

The current yonggun kernel doesn't work with the C1000
I have the same problem--removing the mousedev module does NOT eliminate the twitchy cursor problem.
I am running the Angstrom 2.6.23 kernel from the 20071030 snapshot for the C1000.  Everything else works, including suspend/resume, apm, etc, except for cpufreq (not a high priority at the moment) and this.

Here's my /etc/ts.conf (snarfed from Angstrom):

Code: [Select]

# Uncomment if you wish to use the linux input layer event interface
module_raw input grab_events=0

# Uncomment if you're using a Sharp Zaurus SL-5500/SL-5000d
# module_raw collie

# Uncomment if you're using a Sharp Zaurus SL-C700/C750/C760/C860
# module_raw corgi

# Uncomment if you're using a device with a UCB1200/1300/1400 TS interface
# module_raw ucb1x00

# Uncomment if you're using an HP iPaq h3600 or similar
# module_raw h3600

# Uncomment if you're using a Hitachi Webpad
# module_raw mk712

# Uncomment if you're using an IBM Arctic II
# module_raw arctic2

module pthres pmin=1
module variance delta=30
module dejitter delta=100
module linear
I'm using Angstrom's Xfbdev kdrive X server and their libts libraries (from the same snapshot).  I've modified my .profile to export TSLIB_TSDEVICE=/dev/input/event1 before starting X.  My touchscreen works, and I can use ts_calibrate (from Angstrom) to tweak it, but the twitchiness is still there.  The strange thing is, this doesn't happen on Angstrom (even when booting from SD).  I'll see if there's anything else I might have forgotten to copy over...

Kind regards!

EDIT:  Hah!  Got it working!  I copied over Angstrom's /usr/lib/X11 directory (which I didn't think did anything, given that it only had a Xcms.txt file in it), and I eliminated some remaining libs of xfce4 (specifically, libthunar-vfs-1-2, libthunar-data, libxfce4mcs-client3, libxfce4util4, libxfce4mcs-manager3, libexo-0.3-0, libxfcegui4-4 mousepad xfce4-mcs-manager xfce4-mcs-plugins xfce4-utils xfmedia) which I no longer need now that I'm using IceWM.  I'm not sure exactly what got it working, but whatever it was, the jitter is gone.  Yay!
