ok, that's fine...

after adding swap, it seems to work

hello

so i did what you said, and got the same error as when i tried to plug it in an usb-hub with power...

i didn't check the first time this error, but now, i try to understand it.
you can see it on :
http://pastebin.com/JLwwi7pB

it looks like i lack memory....
but, when i do free -m :

Mem: 59 42 17 0 5 17
-/+ buffers/cache: 19 40
Swap: 143 2 140

so i don't really understand. Do you have an idea ?
(i'm using your kernel config, utx, with some minors change
thank you a lot !

the power saving is a real problem, especially if the nano-wifi is inside the zaurus, and can be not plugged out when not used. my solution to add an external usb female (big) comes out again...

echo 1 >/sys/bus/usb/devices/1-2/bConfigurationValue

Power saving is not such a big problem, you just have to implement RFKILL to decrease power consumption to zero when not in use. It is always a good idea, even the best WLAN needs 10mA in power saving modes.

with my new edup ep-n8508, i tried what you told :
echo 1 > /sys/bus/usb/devices/usb1/bConfigurationValue

Sadly, when i plug wifi, i get :

rejected 1 configuration due to insufficient available bus power.

Do i miss something ?

I have this one. It works well and has a good sensitivity. It even can run with 180mA power which unmodified Zaurus can provide. It can run on 3.3V and it is possible to implement hardware rfkill without external parts. It is small enough to fit inside Zaurus SL-C3x00 (in the space between battery connector, infrared and ioport).

This place seems small to make wifi fit, but i saw you only kept wifi module. Do you have any picture of the module in the place (infrared...), and, what would be great, the wires from where to where they go... i wanna see/know what wires must connect even if finally, i don't touch the inside of the zaurus not to break it...

There are following problems:
It claims 500mA. You have to tell to kernel that it is OK.
Ralink driver is poorly written and wants large contiguous pieces of memory. (It's hard to allocate it on a longer time running system.)
Power saving mode is not optimal. I can imagine better saving.

where to tell the kernel it's ok (which option of the .config ?) ?
i hope rtl8188csu won't take too much memory, i already bought the nano-wifi... would be sad.

Why you need large or no USB? Buy or build an adapter. If you damage a standalone connector, the loss would be just about one dollar.

i'd like a large USB because the nano wifi onto wouldn't break the zaurus shape... an adaptater onto the small usb would be bigger than the NANO-wifi... it's so small... have you seen the picture on my first post... it's smaller than your mini-wifi...
2nd, with an other usb entry, i could fit keyboard and wifi, keyboard and mouse ... without carrying the external usb-hub.

Quote from: utx

The free space below arrow crosses has only 14mm x 22mm. And there is a distantion stand, which could make an obstruction for the wireless signal. Take in account that you need ideally at least 5mm of non-conductive (free) space around antenna. (Well, my dongle definitely does not fit there, but I hope that a small Bluetooth module may fit there.)

i understand the problem, but with you wifi module into the infrared (...) place... the problem isn't the same ? i thought the place under arrow key was bigger...

Quote from: utx

Changing resistor to 1K sounds interesting, but I am thinking about software switch for it (so kernel can compute whether it is possible to provide 500mA).

that was what you told me above with the kernel ? yeah, would be less dangerous that switching the resistor... how do we tell kernel to give more power if needed ?

Quote from: utx

I already have everything ready for the WLAN and an idea about Bluetooth, but not yet done anything of it.

please, do not hesitate to post here the thought and try you do, with picture if possible... i'd like to learn all about this.

Thx a lot

C1000/3x00 Hardware / 3100 Optimisation

« on: November 04, 2010, 11:52:56 am »

hello

i've got my 3100 with cf for wifi and gps ; usb for external keyboard.
software : kexecboot and debian sid
kernel : 2.6.36

i wish i enhanced some stuff, and i need your help to know if what i'm thinking is possible.

1) replace the 4GB micro-drive by a CF of 16 or 32 GB ; is there any limitation on the CF card GB size ?

2) I'd like to run wifi and gps at the same moment sometimes. here is my idea :
i'd like to get a "nano wifi" (like this one : http://cgi.ebay.com/Mini-EDUP-Wireless-N-1...b#ht_5120wt_883 )
chipset rtl 8188 csu, supported according to this thread : http://ns.spinics.net/lists/linux-wireless/msg47477.html

and here i have several solutions...
* if possible, transform the big USB in mini USB.
* add a big usb female adapter in my zaurus. i found a place to make it fit under the arrow cross (down right of the keyboard).
* remove the USB adapter, keep only the wifi module, and make it fit under the arrow cross.

the second and third solutions are the ones i prefer, especially the 2nd (new usb female adapter). it would need to change the resistor to 1K (according to albertr, see : http://www.penguin.cz/~utx/zaurus/www.iral...aurus/wireless/ )
add an hole in the zaurus (under the arrow cross), and have 4 electrics wires run into the zaurus to the usb female adapter.
(the third solution requires the same wiring, but no hole in the zaurus).
i obviously can't wire it myself, i don't have the skills. but i wonder if i knew exactly what must be connected "where" and "to what", maybe i could find an electrician near my location that could wire it for me (4 wires, and the 1K resistor).

i need you to advise me about that, what you think about my wishes (CF, and usb nano-wifi).

thank you

6000 - Tosa / Debian On Tosa

« on: November 02, 2010, 08:48:32 pm »

hello

i'm setting up debian on a tosa's friend device.
i was wondering what i should modprobe in order to ifup wlan0

for the moment, i

modprobe prism2_usb

which gets me usbcore too.

but i get a :

ioctl[SIOCSIWENTODE]: No such device

i read that i should use
/sbin/usbctl on 1

but can't find this ; anyone know in which package i could find it, or the program that replace it ?
thx a lot

Ubuntu / Problem Booting

« on: October 23, 2010, 08:07:58 pm »

hello,

i use a sl-c3100
i have untar zubuntu-desktop and spitz-root_addition, taken from : http://www.omegamoon.com/blog/index.php?en...ry090829-014821 : zubuntu 2 for spitz.
on my sd card (/dev/sda1)
on my sd card i have a swap (/dev/sda2)

on my hda1-2-3-5, i have a debian.

since today, i installed kexecboot (i tried 2.6.2, 2.6.34-rc-3 and 2.6.34-rc4), i can't boot on my debian, kexecboot don't see it (before i use u-boot).
kexecboot sees the zubuntu zImage on " /mnt/boot/zImage" on sda1. when i try to load it, just, after recognizing the partition on my hda
zubuntu blocks (won't continue) on this message :

waiting for root device /dev/mmcblk0p1....

the only key of the keyboard who is "recognize" at this point is "on/off"... it tells me that i pressed it when i push it, but the zaurus won't stop. to stop it, i have to remove the battery and the power cable.

what can i do to make something work (old debian, zubuntu... other) ?

ask for others details if needed.
Thank you :)

edit 1 : problem solved after reinstall total of cacko and reinstall zubuntu

edit 2 : after a while booting zubuntu or debian, both on sd card, with kexecboot, problem reappeared (i don't know why).
it seems that only reinstall cacko doesn't help the problem.
i remembered installing android after cacko. and then, reflashed with kexecboot (2.6.34-rc4) .
but no, still doesn't work.

i obviously miss something, but what ?
does anyone as a clue to pass this :
"waiting for root device /dev/mmcblk0p1..." ???
thank you a lot

Debian / Howto Install Debian ; Help

« on: October 23, 2010, 06:12:16 pm »

hello,

i want to reinstall debian on my sl-c3100, but most links are dead.

for example :
http://armel.applieddata.net/developers/li...root-fs.tar.bz2

so, as i can't find this armel-root-fs.tar.bz2,

i can't follow the instruction of : https://www.oesf.org/index.php?title=Q18:_I...ternal_drive%3F

btw, i have installed kexecboot ; i think it won't be a problem even the above howto explain with uboot ; i hope so...

thx

« on: January 29, 2010, 12:44:59 pm »

hello,

i wish i upgrade to last kernel (at least 2.6.31, better : 2.6.32) ;
may i only apt-get install linux-image-2.6.32-trunk-versatile (or an other, like : linux-image-2.6.32-trunk-ixp4xx... which one ?)
or do i need to flash kernel an other way ; could someone tell me where we could easily find everytime the newest kernel ?

thank you

right, i'm ashamed about my post,while you pointed it to meu
i followed jpmatrix post on irc without looking to 20r0 said, it's all my fault.

about screenrc.tar.gz :

i'm really unhappy with it, because i "tar zxvf" it in my " ~ " directory, and it erase my ".bashrc" to put a new one... i lost all my bash config, and that sucks a lot.

Be careful guys.
