5x00 General discussions / Openzaurus 3.5.3 With Unionfs Support
« on: October 02, 2005, 07:08:15 am »
It's currently unionfs-1.0.11 (vanilla) and yes it isn't really stable, but it works if you use the "correct" (read working) fs parameters or you get oops. For exaple:
If one of the branch is ro mode and you have set delete=all, then it oops;
If one of the branch is ro mode and you have set setattr=all, then it oops;

5x00 General discussions / Openzaurus 3.5.3 With Unionfs Support
« on: October 01, 2005, 11:04:34 am »
Hello.
I have made some modifications in OpenZaurus with unionfs as a default root filesystem.
mtdblock4 is mounted in rw mode, but in union it's in ro mode (you can change it by altering /media/realroot/sbin/init.unionroot, if you dont' t llike it)
mtdblock6 mounted as /media/ram is on higher level branch in unionfs, so everything you write to / is actually written to /media/ram/packages.

I did not include unionroot-utils, because I didn't like their behaviour, these need some improvements.

If you want to test modified unionroot-utils, then send me PS or e-mail.
If you have programs installed to CF or MMC/SD card, then currently you can use them by adding unionfs branch with command:
Code: [Select]
unionctl /. --add /media/cf/packagesor
Code: [Select]
unionctl /. --add /media/card/packagesand before unmounting:
Code: [Select]
unionctl /. --del /media/cf/packagesor
Code: [Select]
unionctl /. --del /media/card/packages
Why unionfs?
Because it's stackable, you can merge the contents of directories, so you don't have to hassle with these symlinks anymore.
One more thing: I can use unionfs to save internal flash from wear levelling (maybe I'm paranoid?)

zImage-collie-40-24-2.4.18-rmk7-pxa3-embedix-r22.bin
opie-image-collie.rootfs-2005-09-30.jffs2 (unionfs-1.0.11)
opie-image-collie.rootfs-2005-10-02.jffs2  (unionfs-1.0.14)
opie-image-collie.rootfs-minifo-2005-10-03.jffs2  (mini_fo-0.6.1)


EDIT: OK, I have tested it for couple of days for now and found it sometimes gives still Oopses  Here is a demostration:

 [ Invalid Attachment ]

I have tested unionfs-1.0.14 as well and that didn't work at all, because setattr,delete=first mount flags were removed in that version. After chmod or write or etc working process freezed completely.
So, i think my next try is minifo filesystem.

Does it work with collie?

Thanks

EDIT: Damn, seems not, dmesg gives me a lots of write errors. I have to return it.

Hi
Enter this command
ldd /opt/QtPalmtop/lib/xmms/General/libQPEgui.so
what´s the output?

I remember that I had same problem, that xmms strarted with no errors, but without gui. I don´t remember what the problem exactly was, but I think it has something todo with libQPEgui library

@comcute: Might be best to speak to offroadgeek, however in the meantime I can host it (and I'd like to use it too :-)).
look at http://www.zaurususergroup.com/modules.php...file=index#LAST
It's currently fist one in the list. I talked to offroadgeek and he doesn't know why I get this error, so I'm hosting it myself.

btw, I forgot to include config file, but it doesn't really matter, if you don't use http streaming.

Give it a try and tell me how is it working

Oh, if it complains zlib not found and you have zlib1g installed, use -nodeps switch (zlib and zlib1g are the same, but different name)

Site Suggestions, Requests, and Updates / UPLOADS DO NOT WORK
« on: July 20, 2004, 04:36:33 pm »
I tried upload section again, and I was logged into the main site.
I did 2 tests.
Fist I tried to upload 890880 bytes (870KiB) long file and it didn't work. Firefox error says: document contains no data. Links error was broken pipe.
Then I tried with smaller file, it was 264038 bytes (258KiB) long and it uploaded well.
It's far away from the 2MiB limit.
Am I doing something wrong?

Wonderful, how do we get hold of it?

I can host it if you want (assuming I can remember my ftp password ;-)), or why not stick it in the ZUG downloads section.


Si
I tried to put it to the download section, but it didn't work either.
I got this error

Hello all.
I didn't find anywhere xmms compiled with gcc3, so I compiled it myself and I want to share it for others.

Strange I can't attach file
Anyway you can download it from http://perses.net/~comcute/xmms_embedded_libs.tar

OpenZaurus/Opie/Qtopia / OpenEmbedded success story
« on: July 17, 2004, 07:23:06 pm »
Ok, I found the cause of this problem.
OE environment was calculating CONFIG_MTDRAM_ABS_POS parameter wrongly
in file openzaurus-sa_2.4.18-rmk7-pxa3-embedix20030509.oe there is line:
addr=`echo "obase=16; ibase=16; C000000 + $mempos" | bc`
but there should be one more zero, then the correct one is:
addr=`echo "obase=16; ibase=16; C0000000 + $mempos" | bc`

Hi
I'm trying to compile 2.4.18-rmk7-pxa3-embedix linux for my collie with oe environment.
Kernel is booting OK, but I can't use mtdblock6.
mtdblock6 is there, but it contents are changing all the time.
It is really strange. I can't figure out what the problem is.
Does someone know what causes this?

in local.conf I have:
ASSUME_PROVIDED = "virtual/arm-linux-gcc-2.95 virtual/libc"
MACHINE = "collie"
DISTRO = "openzaurus"

part of kernel config:
CONFIG_MTD_MTDRAM_SA1100=y
CONFIG_MTDRAM_TOTAL_SIZE=32768
CONFIG_MTDRAM_ERASE_SIZE=1
CONFIG_MTDRAM_ABS_POS=E000000
CONFIG_CMDLINE="console=ttyS0 root=/dev/mtdblock4 rootfstype=jffs2 jffs2_orphand
_inodes=delete mem=32M"


# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00020000 00020000 "Angel Monitor"
mtd1: 00020000 00020000 "CF Updater"
mtd2: 00080000 00020000 "Diagnostics"
mtd3: 00100000 00020000 "kernel"
mtd4: 00e20000 00020000 "jffs2"
mtd5: 00020000 00020000 "angel stuff"
mtd6: 02000000 00000400 "mtdram"

Everything looks normal, but now interesting part starts:

This filesystem will be automatically checked every 24 mounts or
180 days, whichever comes first.  Use tune2fs -c or -i to override.


# mount -t ext2 /dev/mtdblock6 /mnt/ram/
mount: wrong fs type, bad option, bad superblock on /dev/mtdblock6,
       or too many mounted file systems

I'm compiling kernel with "oemake openzaurus-sa" command
I have tried oe-exported tarballs and CVS server version, but the result is the same
