Zaurus - pdaXrom / Cat /proc/stat

« on: February 23, 2006, 10:21:17 am »

I noticed that when a friend runs cat /proc/stat on his 5500 (running OZ) he gets info in the disk_io field. Myself with a C1000 run pdaXrom Beta1 and a Kinsgten 1Gig SD card do not.
Am I missing something?
[div align=\"right\"][a href=\"index.php?act=findpost&pid=115825\"][{POST_SNAPBACK}][/a][/div]

mine says:

disk_io: (3,0):(1493,1416,12674,77,832)

What does that mean, anyway?

Zaurus - pdaXrom / Pl2303 Support?

« on: February 22, 2006, 02:49:12 pm »

The drivers are part of the kernel - as far as I can see, there are a number of options under 'USB Support => USB Serial Converter Support =>' in the kernel config. None appear to be enabled by default though, so it looks like you will need to recompile a kernel to get this support...

Ok, where can I get the kernel source?

Does anyone have any source for pl2303 support for pdaXrom?

Thanks!

isn't it in the kernel source under usb?

Well, is it one of these?

[a href=\"http://mail.pdaxrom.org/rc12/src/libusb-0.1.10a.tar.gz]http://mail.pdaxrom.org/rc12/src/libusb-0.1.10a.tar.gz[/url]

http://mail.pdaxrom.org/rc12/src/usbdconfig-1.0.2.tar.bz2
http://mail.pdaxrom.org/rc12/src/usbutils-0.11.tar.gz

Or is it somewhere else?

I'm not sure what you mean by 'under usb'...?

Does anyone have any source for pl2303 support for pdaXrom?

I looked on the pdaXrom feeds, but didn't find source or binaries for these, which are needed by usb-serial dongle thingies.

I use an SL6000, if that matters, and I have rc12 running.  

I could compile it, but have been unable to locate source and can't seem to google it.

Thanks!

Zaurus - pdaXrom / Where Can I Find Getconf?

« on: February 12, 2006, 01:10:41 pm »

Has anyone tried to build MySql 5 ?
I tried it and ./configure blows up because I don't have 'getconf'.

Does anyone know where I can find getconf? I didn't see it in the pdaXrom feeds

Thanks

Software / Gnuplot Question

« on: January 26, 2006, 11:30:53 am »

It looks like the input is a text file, so even if Gnuplot doesn't support what you want, you could run:

Code: [Select]

tail -n 50 data.txt > last50.txt

And then use last50.txt

Hi,

i am new here, so i really do not know where to post this. Hope i'm right here.

My question is:
Is there any possibility how to plot only the last (let's say 50) values (rows) from an external file using GNUPLOT ?

something like: p [last-50:last] 'data.txt' u 1:2 w l 


I hope someone knows the answer - if there is any.

Thanks in advance for trying to answer.

Best regards
Michael

Zaurus - pdaXrom / Advancemame And Advancemess

« on: January 24, 2006, 05:08:14 pm »

Have you tried mspacman on your version of xmame.SDL?

Also, I looked at the GP2X mame page you posted - looks like they are coding to 0.34 or so!

Has anyone tried xmame.SDL 0.34 ? I think I'll try that later on, but I don't think my 0.77 roms will work.

Are you using a 6000? I can't get time to work unless I use the overclock app and set the three numbers to 3/3/2, which tells me it's 530.84MHz.  If I can get it to go to 624, I bet it would run the older games just fine.

Did you run it from the console? I know it will perform better out of the GUI environment.

Also, I noticed that the xmame.SDL (version .101 or so) that they have been building is a *HUGE* executable.  I think that the size of the thing is causing problems.  That's why I went back to 0.77 (plus I have a few 0.77 roms).  I just built the older stuff I was interested in, and it's still 20.6MB.  I don't need a swapfile to run the 0.77 version.  If you have a swapfile and swapping is occuring to an SD or CF card while playing, it will NEVER be fast.

I think a smaller executable would also help with the speed.

I don't see the point in building a "recent" MAME, as the newer games don't have a prayer of running on the Z anyway.

As far as the M68k and Z80 emulators - of course they are in xmame.SDL with arm-specific code, or MAME wouldn't work.

I'm also curious to know why I can only get 28FPS with MsPacman with sound sampling at 8KHz.  I don't know much about linux-based profiling tools, which would help figure out where to optimize.  I don't have those games you mentioned, but if you have MsP, how many FPS will it run at?

Yuck!

I got xmame.SDL running (under Cacko) on my Z last night and even when running @ 624Mhz with the sound off and autoframeskip I could only manage 3/4 fps under Crude Busters and TMNT- unplayable really.
[...]
I know that there is ARM-specific code for emulating the M68k and Z80 processors as many of the GPX2 emulators use this code- is it not in the main MAME source tree?  I'll have to check. If not then thats why somebody needs to port the GP2X MAME over.

Actually, the performance is not that bad.  I can run things like MsPacman at around 28FPS on my 6000, but I have to overclock, exit X, and set the sound sampling frequency a bit lower.  

Without sound, it does around 30FPS.  It's definitely playable, not at all a "fraction" of what it needs to be.  If it weren't for the sound being a bit scratchy, it would be just like the arcade version.

I use xmame.SDL for the above. I don't have it in an IPK, but I have the executable I built, which is xmame 0.77.  I have no idea if that works on Cacko - it works for me on pdaXrom, though.

I tried the first pdaxrom beta on my C3000, but I'm going to wait for either beta3 or the first stable C3000 version before I ditch Cacko. I haven't been able to get any version of MAME to run under Cacko so I dunno how MAME performs on the Z at all but from what people have been saying it performs at a fraction of the speed I'd imagined- struggling to play ms. pacman on a 6000!? The GP2X MAME can supposedly even play the Neo Geo games at a decent framerate on a 200/250(overclocked) ARM CPU. It uses ASM ARM CPU code which presumably this version of MAME people have been trying doesn't. Maybe they just missed some optimisations out in the makefile?

I'd be grateful if someone could point me to a SDL MAME package for Cacko that works (under console SDL preferably)

Thanks!

Are you expecting GP2X Mame to perform better than xmame.SDL?

Why would it be faster??

Anybody had a go compiling the GP2X MAME for the Z yet?

I've not got round to doing any cross compiling yet but I want this pretty bad so it may be the first thing I attempt. I'd like to get it compiled to work with SDL from under a Cacko console though (the one you get to by pushing / on boot)- is that possible? I've not yet seen this working, but I've heard you can run SDL under the console on pdaxrom so I don't see why not. Other SDL stuff I've ran under Cacko had to be run from konsole under QT and then the screen was 640x480 giving a small image and I'm after 320x240.

I should imagine that the only thing that would really need to be changed are the controls as they will obviously be mapped to the GP2X's pad, otherwise its a piece of code for xscale linux so I'm hoping it will be an easy job to get running.

Anyone know of a good guide to cross-compiling progs for Cacko? (1.23b if it matters)

C1000/3x00 Hardware / Please Help, Usb Host Problems!

« on: January 17, 2006, 05:10:04 pm »

What command are you using? It doesn't sound like a cable problem.

Just got a 3100, its great - really pleased with it. But I cant mount anything on USB host.

Ive tried pdaxrom, cacko and am about to try OZ but am starting to think it is broken. I make a directory, try to mount and get

mount: mounting /dev/sda1 /mnt/test failed: no such device or address

This is the same on my camera, hard drive and usb memory stick - no luck with any

Also havent got the mouse working either, ive tried everything ive found on the forums.

Connecting the zaurus to my linux desktops works fine, the zaurus hard drive is loaded in kde, so i think it must be the host cable. But it was brand new.

Plese someone help, perhaps I am missing something stupid out.........

Thanks.

No SD cards over 1GB will work in the Zaurus.

CF cards > 1GB are ok, though.

Zaurus - pdaXrom / Usb Networking And Usbfunction.py

« on: January 12, 2006, 09:32:57 am »

Is your /etc/hotplug/usbdnet.conf set up properly?

For example, here's mine:

Code: [Select]

#IP=192.168.129.201
#NETMASK=255.255.255.0
DHCPS=no
DHCPC=yes

This sets up the Z so it get's its IPAddr from my WinXP machine when I plug it into the cradle. You don't need to run any utility to modify settings here - I just used a text editor and changed what I needed.  Make sure you put the string "yes" exactly for things you want enabled (see /etc/hotplug/usbd.func)

You don't need to explicitly run anything, it automatically executes the script /etc/hotplug/usbd.func when you insert the Z into the cradle.

Do you have any useful messages from /var/log/messages, or dmesg output? There may be clues there.

Zaurus - pdaXrom / Basic Hotplug Questions

« on: January 11, 2006, 03:59:30 pm »

Ok, I have this working now so that two things happen when I insert the SL6000 into the USB cradle (talking to Windows XP)

1) The screen rotates with xrandr

To get this to work from /etc/hotplub/usbd.func, I had to setup the environment a bit, like so:

Code: [Select]

       # Screen rotate
        if [ "$ROTATE" = "yes" ]; then
            export HOME="/home/root"
            export PATH="$PATH:/usr/X11R6/bin"
            DISPLAY=:0 /usr/X11R6/bin/xrandr -o normal >> /etc/hotplug/usbd.log 2>&1
        fi
2) VNC Server launched

Same fix as above:

Code: [Select]

       # VNC Server
        if [ "$VNCSERVER" = "yes" ]; then
            DISPLAY=:0 /usr/local/bin/x11vnc_control stop >> /etc/hotplug/usbd.log 2>&1
        fi
The problem I'm still having is that when I remove the Zaurus from the cradle, the hotplug events don't seem to work.
