The B-type plug on the 5500 DC power supply: inside is hot, outside shield is ground.

Sharp ROMs / /etc/fstab Gone (hybrid Rom On Sl-5500)

« on: November 01, 2005, 05:51:47 pm »

mount man page (found here) shows how to give the mount command more information:

mount -t msdos /dev/something /something

The fstab file just gives you the shortcut of not adding the extra arguments to mount. (mount man page is here.)

Angstrom & OpenZaurus / Rom Confusion

« on: October 26, 2005, 04:49:00 pm »

Here are my OZ quick installation and bringup notes for the somewhat lazy.


When I first picked up a 5500 a few weeks ago I went through the following steps:

Installed the latest OZ-gpe since I wanted X, not qpe.
Encountered instability - perhaps due to operator error.

Installed the latest OZ-OPIE.
Found the Cancel button bug.
Couldn't get the WCF12 up immediately.

Installed Hentges' latest OPIE, skipping cardfs (for the too-big card-found-dialog bug).
Copied cardfs.bin from Win2k onto FAT SD then to 5500 memory.
Formatted SD as ext2 and moved cardfs.bin back to SD.
Installed cardfs from the cmd line.
Manually moved /home, /opt and /etc to SD (no need to remove the card) then sym-linked /media/card/home to /home, etc.
Brought up WCF12 with no issues.
Browsed the unstable OZ feeds from a desktop machine and scripted the:

ipkg install -d sd <stuff>
ipkg-link add <stuff>

for the packages I wanted.
Tried the OPIE PIM and mail and was vaguely unhappy with it so I installed KDEPIM 2.2 (to have the same version as the memory-stick).
Copied the mem-stick kapi/kopi to a usb drive and synced it to the 5500 with no issues (from Win2k box).
SFTPd from FileZilla with no issues except adding password to root.
ssh'd from cygwin with no issues.


I spent no more than ten minutes on each of the first two ROMs above before trying something else. What took the longest in Hentges' was deciding to always have the SD mounted.

Now I have what I wanted from the 5500: a relatively stable PIM/mail system that I can do some c, octave and perl work on. Since mail is IMAP and kapi and kopi stay synced to my desktop, all I have to do is zip my source code and pwmpi.data (ok, and wellenreiter dumps) and send it to gmail every day. That way I can try 3.5.4 gpe after pre with only a quick update to my-ipkg-install.sh.

5x00 General discussions / Does Kpwm, Come In Pi-sync Package?

« on: October 20, 2005, 03:51:07 am »

I downloaded it, and it does. However, it doesn't work. I get the little hourglass on the start bar, but it quits on me. It doesn't start.

I'm rather new with the 5500 and I'm running oz, not Sharp. When I ran 'pwmpi' from the command line I got this error:

Code: [Select]

pwmpi: error while loading shared libraries: libstdc++.so.5: cannot open shared
object file: No such file or directoryIn this thread Fatty shows .so.5 is here: http://212.10.30.205/rc10/Zaurus-Collie/fe...x_5.0.5_arm.ipk
After installing it, PWM/Pi works.

Also, how do you kill a defunct process?

If there is a console, use 'top' or 'ps' to list processes, then use 'kill' to stop one by pid.

Angstrom & OpenZaurus / Oz 3.5.3 - Opie Battery Applet Hangs The Z

I can't find this bug in mantis. Any objections to me adding it? This freeze is very reproducible for me (config in sig). Button presses and screen taps do nothing. The screen doesn't even dim. REPLACE BATTERY reset does work. ssh stays functional:
