Angstrom & OpenZaurus / /var Is Empty

« on: May 29, 2005, 01:57:35 am »

Whoa!

Total install killer for a 5500 and _no-one_ responds? I'd discount it as holiday-weekend blahs, but developers are responding elsewhere.

Where are the Oz-Team developers? Lardman, Mickey, whomever?

When booting a fresh install of OZ 2.5.3 my /var dir is hosed within _minutes_.

Is it that the 5500 is of no concern?

This happens on two different 5500s.

Angstrom & OpenZaurus / /var Is Empty

« on: May 27, 2005, 01:33:35 am »

Zaurus model: 5500
kernel version: 2.4.18-rmk7-pxa3-embedix
opie
last upgrade date: fresh install

After installing 2.5.3 I was merrily oz-ing along when I decided to shutdown. I did so and  reboot proceeded normally through the opie startup...then no opie, just a blank screen.

I docked it and luckily usb networking was up, so I ssh'd over and started opie from a console so I could read the messages. They appeared normal, but no opie.

To make a long story short, I stumbled into the /var directory and it was totally empty.
Plus, tmpfs is mounted over var multiple times.

root@collie:/# df
Filesystem           1k-blocks      Used Available Use% Mounted on
/dev/mtdblock4           14464     13624       840  94% /
/dev/mtdblock6           31729        18     30073   0% /media/ram
tmpfs                    15080         0     15080   0% /var
/dev/mmcda1             241145     97299    131395  43% /media/card
tmpfs                    15080         0     15080   0% /var
tmpfs                    15080         0     15080   0% /var
tmpfs                    15080         0     15080   0% /var
tmpfs                    15080         0     15080   0% /var

Of course the z is unusable. This has happened with multiple installs and two different 5500s.

Note: I just discovered that if I reboot and unmount /var the contents are recovered. So empty filesystems are being mounted over /var??

Note2: This remounting of /var is happening continually. I "fixed" things for now by tarring up /var and recreating it in /media/ram. I then commented out the tmpfs->/var mountpoint in fstab and made /var a symlink to /media/ram/var.

Note3: As expected, the "fix" didn't work

Angstrom & OpenZaurus / Zaurus: Remote Control?

« on: February 08, 2005, 06:33:32 pm »

I have  connected a pc to my stereo with my CDs encoded to mp3. On my debian systems I can issue: ssh -n -f -l root kathix.elkins xmms and control songs, playlists, whatever. However, I'd like to use my Zaurus 5500 as a pseudo-remote via wi-fi. After installing OZ 2.5.2/GPE and issuing the command above I get:

WARNING: Ignoring unknown argument '-n'
WARNING: Ignoring unknown argument '-f'
ssh: connection to root@kathix.elkins:22 exited: No auth methods could be used.

I installed OZ with GPE so I'd be able to take advantage of X. I'd appreciate a clue as to how to get this working!

BTW, I've tried VNC and was not impressed. My goal is to have remote xmms running on the Z with minimal overhead.

Help!

Qt/Qtopia / Request for help

« on: December 13, 2003, 12:14:21 pm »

Help! I\'d like to ask a big favor.

I\'m struggling with making the shift from procedural languanges to OOP and I\'m badly stuck.

I have a small program that displays an input screen. It needs to respond to a button press, then display a new screen. Both screens are defined, as mentioned in another post, I can display one or the other.

I\'ve been trying QWidgetStack, looking at source code from the SDK. etc, as yet w/o success.

Would someone be willing to examine the code and put me on the right path?

It\'s very trivial, one .h file, one main.cpp and one body .cpp

my email is jeffelkins@earthlink.net

TIA

Qt/Qtopia / help with crosscompiling

« on: December 12, 2003, 09:09:31 am »

Using \'source\' did work.  Using \'.\' did not.

I also installed an updated bash rpm from redhat with no change.

Thanks for the help

Glad it worked out...

Running the scripts doesn\'t work for me either (Debian Sid.)

Try using the command \'source.\' or \'.\'

i.e.

source dev-arm-qpe.sh

or

. dev-arm-qpe.sh

Qt/Qtopia / C++ newbie

Thanks.

Can you recommend some example QWidgetStack code...something that compiles, that I could modify and learn from, but goes beyond \'hello world\'?

Qt/Qtopia / C++ newbie

« on: December 08, 2003, 09:12:00 am »

I\'m trying to move into c++ for the Zaurus and am at the baby step stages.

I\'ve had some luck with apps that have only one screen and am now trying to develop one that displays two. With the code below, I can display either ScreenOne or ScreenTwo by commenting out one or the other. My goal is to  have the button on screen 1 call screen 2 and vice-versa.

My coding background is limited to procedural languages. I\'m working with the \'Thinking in C++\' books,  but this my first exposure to OOP.

Can someone help a newbie?

Thanks
