Zaurus - pdaXrom / SD / CF card speed measurement

« on: August 27, 2004, 04:14:42 am »

Its quite interesting about the SYNC parameter. It took me about 5 min to thrash the SD card after installing 1.1.0-RC2 since the SYNC parameter wasn't set in the fstab file. I added it and reformatted the card and no problems so far.

I cant remember exactly but I think that my performace for both write and read was about 23 sec, no too bad anyhow.

Zaurus - pdaXrom / SD / CF card speed measurement

« on: August 27, 2004, 02:10:12 am »

Hi

I guess that the count argument to dd is not in bytes but in blocks. Each block is 512 bytes, that gives the 32MB file size. (Please correct me if I'm wrong)

Anyhow, have you guys had any problems with corruption while doing your tests? I have had some major SD corruption since I bought my Sandisk card. The only thing that helps is to include the sync parameter when mounting.

Zaurus - pdaXrom / Mplayer w100 api files needed...

« on: August 18, 2004, 03:32:53 am »

It was awhile since I ran standard ROMs but I think kino2 uses the QVGA mode. When speaking of it, I couldn't either switch to QVGA and plot there. Could there be some problems in the libs we are using or are we not using it correctly?

Zaurus - pdaXrom / Mplayer w100 api files needed...

« on: August 18, 2004, 01:20:32 am »

Hi guys

I also gave mplayer-vidix a shot and ended up with vidix support but no scaling. The image was also rotated and I could not really find any way to rotate it back using the API (hw accel). The API for w100 isn't as documented as one would like (execpt for the header file that some people hacked).

I am quite curious to which w100_vid.c file you are using? I downloaded one of the japanese ones and couldn't get it working so I started to code my own. (I think there was a link to it in one of the previous messages in another thread by doublec)

Maybe we could cooperate on this one to get both mplayer and xine woirking? I guess the vidix driver should be the same for both of them.

Zaurus - pdaXrom / I/O error on sd-card

« on: August 02, 2004, 05:16:16 am »

Hi

I have got a new Sandisk 512MB SD-card and tested it for a while (my previous card failed bigtime and I had to return it to the vendor). This new card will unfortunately also become corrupt if I run it as a usual card (normal mount parameters). I found out that adding the sync parameter to the fstab file fixes my problems, anyone seen the same? The major drawback is that the performance sucks now...

Could the problems be related to concurrent read/writes?

Zaurus - pdaXrom / Playing video in 320x240 fullscreen

« on: August 02, 2004, 05:08:35 am »

I modified the driver to switch the 640 and 480 around and video plays ok using vidix in normal vga now. Issues at the moment are the video is not overlaying the mplayer window. For some reason the overlay is rotated 90 degrees out from the mplayer window. It looks like the x and y coordinates passed to the ATI funtions have 0,0 at the lower left of the screen in landscape mode. I'm not sure what to do about that and the 640x480 issue.

I'm also unable to get hardware scaling working at the moment so full screen doesn't work. The issue with that is the internal memory for the ati w100 only handles 320x240. Using external memory for 640x480 works but the video plays 'wavey' and corrupted. I suspect something is wrong with the driver code there and would need to investigate.

qvga still doesn't work - probably the memory offsets are different for writing to the screen in that mode. More playing needed. Still it looks promising for using the ATI acceleration functions to get better performance out of the video.

Hi all

Have anyone managed to get mplayer to work with the vidix overlay driver the doublec was talking about? I gave it a shot and ended up in pretty much the same spot as descibed in his post. I patched mplayer with w100_vid.c, w100api.h and tweaked the makefile. Overlay seems to work and I guess the speed is fine but with "some" problems:

* Overlay region rotated
* No QVGA mode just 640x480

Anyone tried the AtiCore_YYY functions? I have googled everywhere and cant find any information about the api (guess its hidden from open source projects).

Is it possible to get the source for kino2, I suppose it handles the same functions (mode switch, overlay and so on).

Suggestions?

Zaurus - pdaXrom / I/O error on sd-card

« on: June 01, 2004, 06:03:22 am »

Hi all

I am experiencing exactly the same problems with my brand new Sandisk 215MB SD card (SANDISK SECURE DIGITAL ULTRA II (SD) 512MB)

I just called the local hepdesk here in Sweden and they accepted to replace the faulty SD card without even discussing what had happened. Maybe it is a known error?  :-/ The card worked fine the first two weeks and then it just failed, no unclean eject or similar... This is the symptoms I experience when running the card.

When I checked for badblocks all blocks from 438025 and to the end of the disk are corrupt (bad). (I think it is something like 10% of the total). Block 0 also seems to be inconsistent, sometimes it works and sometimes not.

When copying large amounts of small files to the disk it fails fatally after some time, no files can be read after the failue.

# cp /mnt/cf/card-backup/cramfs/zsdk-1.0.5.1.cramfs  .
cp: unable to open `./zsdk-1.0.5.1.cramfs\': Input/output error

Anyhow, I have to wait until I get the new card to see if it performes better or if the same applies for that.

Anyone got a Sandisk Ultra II 512MB card that works?

Zaurus - pdaXrom / Port Requests Here:

« on: March 26, 2004, 12:17:01 pm »

X11 ports that would make the C750 a killer machine?

For me it would be:

Ethereal + Libpcap
Minicom + Libncurses (or another serial-capable terminal client)
Konsole (or similar with scroll up/dn buffer)
a TFTP server of some kind

Well that\'s enough to be getting on with. If I can get a Dev environment sorted, I may have a go at these myself.

Hi all

If someone is interested I have a working version of ethereal for X11/pdax. I tested it on my 760 and it seems to be able to dump all packets that I tunnel over USB. To be honest the GUI is too small to be very useful but I guess it can be used as a last resort, tethereal is also included for console people. I don\'t have any ftp/web server so if you want it just tell me where to put it...

Version : Ethereal 0.10.0a
