Angstrom & OpenZaurus / issue with OZ 3.3.6-pre1 on SL5600
« on: February 23, 2004, 06:28:16 am »
I\'ve installed OZ 3.3.6-pre1 on my SL5600. I\'ve never used OZ before so please don\'t flame me...

It look like that I\'ve still have the sharp rom structure in /home

Install procedure:
 - flash the OZ files using a CF card
 - reset
 - format
 - oz install all the packages (202 ipks) and boot opie

Here is my mount devices:

Code: [Select]
/dev/root on / type jffs2 (rw,noatime)

ramfs on /dev type ramfs (rw)

proc on /proc type proc (rw)

devpts on /dev/pts type devpts (rw)

/dev/mtdblock3 on /home type jffs2 (rw,noatime)

ramfs on /var type ramfs (rw)


I can\'t install anything, I\'ve got ~500K space left on the root partition...

Linux Applications / ld-config
« on: February 06, 2004, 06:04:18 am »
The sharp rom contains libc 2.2.2 and ld-config 2.2.2.

The blackdown JVM for Xscale is compiled against libc 2.3.x and ld-config 2.3.x.

I\'ve copied the library 2.3.x to /home/zaurus/mylib and I\'ve started the JVM as follow:

Code: [Select]
export LD_LIBRARY_PATH=/home/zaurus/mylib:$LD_LIBRARY_PATH

java -version


the JVM has found my new libc 2.3.x but the new libc is still loaded by the old ld-config.

How can I load the JVM libraries using the new ld-config 2.3.x.

with \"chroot\"?? or LD_PRELOAD??

X/Qt / Xqt
« on: February 05, 2004, 04:37:51 am »
I\'ve installed the Xqt packages on my SL5600. I\'m just wondering if someone done the same thing...

When I start the xserver (version 0.0.7) I get a window without the border/title/exit cross. So I can only kill the xserver from a remote terminal (kill -9). any workaround?

I\'ve installed blackbox, work ok.
I\'ve tried evilwm and I don\'t thing it\'s working.

If I run \"startx\" from a terminal, the xserver set the screen size to 240x300. I\'m not sure is correct it should be 320x240. what do you think?

At last I been able to run AWT application using the blackdown 1.3.1 VM. :-)

General Discussion / ext2 vs ext3
« on: February 04, 2004, 03:01:54 am »
I\'m just wondering what do you think about formating a SD card to ext3.
Is it better than using ext2?

I think with ext3 , you don\'t need to use \"fsck\".

Is it suitable for flash card (CF/ SD) ?

General Discussion / brick my SL5600
« on: February 03, 2004, 03:30:24 am »
This morning, I\'ve done a hard reset on my SL5600 and the green mail light is flashing constantly. If I plug the power then the orange led is flashing as well...

I don\'t know what happen... :-(   what should I do?
Ive done a search on the forum and I can\'t find anything about it.

Sharp ROMs / qtopia 1.7 rom
« on: February 02, 2004, 07:31:58 am »
I\'m currently in progress of building a custom rom for the SL5600 with qtopia 1.7 and libc 2.3.2.

what I\'ve done so far (I\'m using a cross-compiler gcc 3.3.2 from OZ)
  - download the SL-C860 rootfs tree
  - compile jpeg-6
  - compile qt 2.3.7
  - compile e2fsprogs
  - compile qtopia 1.7
  - upgrade the libraries in /lib with 2.3.2
  - copy the qtopia files to /usr/QtPlamtop.rom (bin, etc, help, i18n, lib, pics, plugins, services, sounds)
  - compile/upgrade busybox 0.60.5
  - compile/upgrade tinylogin 1.4

What else do I need to do?

how do I configure qtopia to be recognised by the system? where do I copy the qtopia \"apps\" directory?
do I need to recompile all the default libraries/tools from sharp? (/bin, /sbin, /usr/bin.rom, /usr/sbin.rom)

I\'ve compiled the qt 2.3.7 with qt-zlib and qt-png, is it better to compile it with the system libraries?

I\'ll be my first rom so I\'m a bit newbie...

If the build is successfull then this can be merge to another rom like tckrom...

Linux Applications / cross compiling e2fsprogs
« on: January 30, 2004, 06:33:53 am »
I\'ve tried to cross compiling e2fsprogs and it doesn\'t do it...

$ export PATH=/opt/cross/bin:$PATH

$ ./configure --target=arm-linux --with-cc=arm-linux-gcc --with-linker=arm-linux-ld --prefix=/opt/cross/arm-linux

Quote

It compile the library and tools as x86 binaries...

what\'s wrong? :-(

I need the e2fsprogs library to cross-compile qtopia 1.7. I\'ll try to make a rom with it...

Linux Applications / cpu mode
« on: January 16, 2004, 10:27:57 am »
I\'m currently writing an automatic cpu frequency adjustment software (to be used in conjunction with the overclocking kernel patch). So I can downclock/overclock the cpu based on the user load.

What do you consider the zaurus in idle/busy state?

 idle mode >= 80% cpu idle ???
 busy mode <= 50% cpu idle ???

I\'ve tried to get a feeling using the command \'top\' (refreshing rate 1s), here are my findings:
  - do nothing -> ~80% idle
  - open application -> < 40% idle
  - sharp media player running -> ~50% idle
  - chess Knights computing -> 0% idle
  - chess Knights waiting for user inputs -> ~70% idle

Any comment will be appreciated... :-)

Linux Applications / gcc 3.2

Hi,

Where can I find a FAQ/HOWTO to setup an ARM cross-compiler using gcc 3.2.x?

General Discussion / special kernel
« on: December 22, 2003, 06:07:10 am »
Hello,

I\'ve compiled a kernel (for the SL5600 - poodle) with the following instructions from this site:
http://tetsu.homelinux.org/zaurus/kernel/
If you want to translate to English -] http://www.excite.co.jp/world/url/

The kernel source code is based on the c860 source and 4 patches.

Here are some stats:

### default kernel
Dhrystone Benchmark, Version 2.1 (Language: C)
Register option not selected.
Microseconds for one loop:     4.2
Dhrystones per second:   240639.1
VAX MIPS rating:    136.960

### preemptif kernel -] http://www.tech9.net/rml/linux/
Dhrystone Benchmark, Version 2.1 (Language: C)
Register option not selected.
Microseconds for one loop:     2.5
Dhrystones per second:   402933.4
VAX MIPS rating:    229.330

### special kernel
Dhrystone Benchmark, Version 2.1 (Language: C)
Register option not selected.
Microseconds for one loop:     2.1
Dhrystones per second:   476099.8
VAX MIPS rating:    270.973


I\'v been using a preemptif kernel for about 3 months and I\'ve never seen any problem. I don\'t know about this \"special kernel\" but it\'s really really fast, you can see a massive difference in term of usability!

Let me know if you want the source and the binary. Don\'t know where to upload it on the ZUG...
