have done it but not on a zaurus, its not that hard once you have losetup (which i belive the zaurus dose not have)
anyway you create a file or partition and fill it up with random data (ie dd if=/dev/random/ of=`your file or partition here` bs=1024K count =128) that should fill the directory up with 128 MB of random data (you can skip this setp as it can take a long time and you have to move the mouse and type to help generate random data) i belive doing this for 200GB was calculated at takig 3 days if some one was using the computer 24/7
next you call losetup and bind the file to a loop devices (ie /dev/loopx) with losetup -e aes `path to file or partition` /dev/loop0 (type losetup without any arguments for some simple help as i am doing this from memorey) just a word of warning -e allows you to specify a name, while -E allows yo to specify a number that represents a kernel module for encryption
it will then ask you for a password, chose somthing nice and long
next fromat the /dev/loopx device with mkfs.ext2 -j /dev/loopx
then mount /dev/loopx somewhere and you are done, keep in mind you have to type the password every time you mount but when you remount it is posible to get the mount command to auto allocate a loop device and handel the losetup stuff for you (see the mount man pages near the end)
if you need any more help just post here but the guides work farily well a good one is at www.tldp.org

C1000/3x00 General discussions / Lineo's 2.4.20 Kernel Mess
« on: April 26, 2005, 06:43:23 pm »
so basiaclly the bootloader boots a protected (from erasure) kernel that boots anothe kernel (the one thats copied using updater.sh) if this is the case and i cant rewrite the first kernel then i will start testing tonight (can any one confirm this)
as for the hardware, after looking at the pictures you are right i should have genrelised and said nearly all pxa270 are neraly the same in terms of hardware and that thier is enogh in comman to be able to reuse code from other projects instead of rewirteing them from scratch
plus anyone made it to the mantince area, whats the key combo as i have tried parcticly everything to get it up and it doesnt work (i am talking about the manu that allows you to back up the flash not do a hard reset)

I would love to see 2.6.11 for the c3000, but i hate programing, i plan to build a distro around it when someone ports it
i am part of the axim x30 porting group (on www.handhelds.org) and we just recently modified the code for the x3 frame buffer to work for the x30's framebuffer (which uses the pxa frambuffer like the c3000) so thats done, all you have to do is change some setup registers for the lcd screen in the code and recompile, these can be dumped from linux as sharp nicly set the regesters up so we can see what the os is doing
looking over the hardware the design is nearly identical, the biggest hurdle for me is bricking my c3000 because as far as i can tell you need a working kernel to update the flash
so framebuffer driver is done, pcmcia works out of the box (built in drivers) i suppose the only things we should be concerned about is the sound (not a problem if its an ac97 codec) and touch screen? and perhaps the usb client/host and how to switch between them
i get the felling that the x30 and c3000 were designed by the same people (HTC)

C1000/3x00 Hardware / How To Do Video Out On C3000?
« on: April 25, 2005, 03:00:23 am »
with the io vga out card does that allow you to use the output like a normal vag adaptor or will it only work for applications written for it?
its a shame it the c3000 doesnt have the 2700 video card from intel as that had vga out built in (all it needed was a driver chip) (see the x50 from dell for refrence)

if i rember corectly the linksys WCF54G card uses the atheros wavelan chipset which dose not have driver support (not that i could find) on thier website is a driver for a diffrent card, however someone apparently got it to work (do a search) however the fourm where the infomation is is down at the moment
if you do get it working however PM me as thats the card i wanted to get but was unsure as to wiether it would work

sorry bout that
i have a c3000 with the basic sharp rom
when i first got it the light wouldnt turn on and i had to go to the settings panel and set it all up like you would for a normal card however after this i installed some software (ie wpa supplicant and some games and apps) i also remeber fiddling with wlan-ng.conf to include the name, manfid and driver fields for my card (obtained from cardctl) however i cant remeber if i did this before or after i did the above step (i am inclined to belive it was before)
after this the thing refuses to connect, cardctl says its there cardctl ident 0 returns that it is a network card, however cardctl status 0 returns that it is 0 or nothing basically
iwconfig dosent see it, the prism2_cs module isnt loaded.
basically i am inclined to reset it, i never connected sucsefully to a wifi hotspot when the card was working (i assumed) as all my acsess points were WPA encrypted (none of that weak wep stuff)
anyone have any sugestions, as far as i see it its as simple as a reset but i need wpa to connect and was wondering if this might have stuffed it up, any one got wpa working?

I posted somthing recently about building your own gprs modem from an old clamshell phone, its the same thing except you connect it throgh the serial port of your Zaurus or if you have a C3000/1000 the usb port
apart from that everything is the same (including dialing)

I just recently purchased a NETGEAR MA701, only afterwards did i find the messages about some people not getting it to work and Netgear replacing it instead of troubleshooitng problems with the card when you called tech support
at the moment i have modified the wlan-ng.conf (or whatever it is called) to include my card and i did have it recignised by the OS for a short time, then i installed some programs and now it just ignores the card compleatly
any ideas about what i can try, i have done a search already but there is little infomation i could glean from the posts i could locate
thanks

« on: April 18, 2005, 09:01:25 am »
I was looking into devloping the 2.6 kernel for the zaurus but after looking at the updater.sh it appears that linux needs to be running and WORKING to upgrade the flash
is it posible to boot into a 2.6 kernel from a 2.4 i remember seeing a project for the i386 arch that allowed you to boot a new kernel without restarting the machine and was wondering if there was any other project that was capable of doing this under the arm arch?
if there isnt such a project, is any one intrested in a bios of sorts? that does basic hard ware inislisation for the CF slot and microdrive and then presents a menu that allows you to chose which to boot off, this means you could have your user kernel on the Micro drive under boot and your dev version on a CF or the microdrive and boot off it (think grub for the arm arch (i would start there anyway) i have seen some other arm bootloaders and might even be able to adapt them
it would include, basic serial console support, flashing (of HD and Flash) backup, restore, fsck formating and include a basic linux distro (most likly the basic sharp one) in flash as an emergency recovery console)
what do you think, i just mention this becasue no mater what i tried ui could not bring up the mantince screen for flashing the... flash and would like to be able to select kernels

General Discussion / How To Build A Gprs Modem
« on: April 13, 2005, 02:12:24 am »
I had a good idea for those of you who (like me) want a gprs modem/phone for the zaurus.....
Why not just use an old clam shell phone?
i am trying it with a motorola v8088 at the moment, just need to find a serial cable for it (then a serial to usb cable) and then control it using the <at> command set
i had 5 free phones just lying about with broken screens and decided to give it a try, its not going to cost me a thing (unless it works and i start spending to much time on the net)
best of all the come with thier own power supply so there is no impact to you battery life the bad news however is that you have to use the headphone jack or work out how to control and turn on bluetooth for your phone (if it has bluetooth), however if you had bluetooth wouldnt it just be easier to keep the phonein your pocket and connect to it that way ?
oh well hope this helps those who want a cheap soulotion to both their connection problems and buildup of mobile phone problems you might ant to try keeping the keypad and just lose the screen so you can recive calls without turning on you Zaurus

C1000/3x00 Hardware / C3000 Info
« on: April 11, 2005, 08:20:02 am »
Hi there, just got my c3000 and was quite impresed, however i would like to build my own distro based on the 2.6 kernel and need to find out a bit of info
1. When using the updater.sh script is it posible to overwrite the sharp bootloader/menu causing my device to become a piece of modern art?
2. Is the keyboard interfaced in a simmilar way to the other cxxx's or will i have to find that info out for myself (ie can i just reuse the cxxx stuff in the 2.6 kernel for the keyboard)
3. any info on the backlight, i noticed its a module and was wondering if this would cause me any grief
4. what do all the options in the sharp menu mean (if you hold OK hen rebooting)
5. anyone upgraded their drive to a 6GB hitachi micro drive yet?, i am planing on doing it and was wondering if anyone has any advice
6. what would you like to see in a distro
7. can any of these vga CF cards be used as a frame buffer for display of a terminal or X windows? if not does anyone know of a card that will convert serial output (with stdoutput on it) to vga
one of the things i would like to implment is unionfs to make the read only parts writable and to try and avoid the massive ammounts of symlinks in order to make the filesystem simmilar to a desktop distro
basically when this thing first boots after reflashing you are given a command line with some tools to get you connected to the internet and thats all, you then pick and chose the packages you want, i would also like to get a feed up and running of .ipks as most i have downloaded give me errors (like nCurses, it took me forever to locate a working version) but also have all packages heavily optimised for the c3000 (ie dont care about space only speed)
i want this distro to focus on wifi and the command line (that dosen't mean we wont have graphical output) and speed
luckly for me i have 2 weeks free to work on this, but i fear it wont be enough, thanks in advance
