Is there any way to re-compress the files (that I've already customized) so that I can "move" the system from a 1GB to an 8GB SD card? Thanks for all the help!

[moocapiean]

I can't remember the command I used, but I think this will work.  Open a terminal and type:
cd /
sudo tar --preserve -cjf archive.tar.bz2 /*

That'll create the file archive.tar.bz2 in the / (root) directory.  You can then untar it by doing the following in the top-most location of the SD card (probably /media/<sd_card_name>):
tar -xjf archive.tar.bz2

Has anyone had any success enabling the gamepad or xrotate buttons? I tried running xev to see what it would give me when I tried using these buttons. The rocker pad and the xrotate button did not get captured at all. I got the following output from the gamepad buttons (circle, check-mark, cross and square, in sets of two for keydown and keyup:

I'd like to hook this into xbindkeys, but I don't know how. I do know that the instructions on the wiki for getting xrotate to work in xfce do not work: http://wiki.laptop.org/go/Xfce#Rotation. It causes xbindkeys to not accept any keyboard input. On the other hand, It was intended for the regular xo OS. To me, this indicates a possible driver issue.

I look forward to hearing what people think. Thanks.

Hi, I'm sorry in advance - I have to do a bit of cross-posting here:

In another thread I've concluded my (so far failed ) experiments about trying to force Ubuntu to boot from mmcblk0p2 instead of mmcblk0p1 (together with the reason someone would actually want to do so ) and my (IMHO promising) approach to patch the initrd which forces the boot process to use mmcblk0p1.

Please have a look at this: #25 Re: Multiboot olpc.fth + fstab files

Does this make some sense to anyone who can think of a way to make this actually work?

[koolkat]

I think I have a new issue:

I am using a san-disk 2 gd SDHC card and trying to get Moo's version of Xubuntu working.

After many attempts I FINALLY got it booting off of the SDHC card, but instead of going into ubuntu it is giving the following error and dropping me to a forth prompt

Boot device: /sd/disk:\boot\olpc.fth
<buffer@800000>:33: boot-filt
Type 'help for more information


I am going to check the SD cards olpc.fth for typo's but I am running on Q2D07 and have gotten far enough to try and boot from the forth script on the sd card.  THe one on the nand isnt modified.  I think the bootorder is USB SD Nand, or at least I hope it is otherwise I've hosed everything and need to do an activated "upgrade"

The only problems I had with the instructions were not knowing when to put in mmcblk0 or mmcblk0p1 when translating from the USB steps to the SD steps, and was worried that by mounting mmcblk0 instead of mmcblk0p1 would have hosed the card.  I think it is working though, almost there.

-Koolkat

ANyone know enough forth to write a meny driven bootloaded without having to resort to hitting buttons  say have it load and 1 to boot USB 2 to boot SD 3 to boot nand and 4 to boot old nand files?

I'll try to update the instructions with hints for this later this week.

I don't, but there's another thread that has (I think) what you're looking for: Multiboot olpc.fth + fstab files. I think the thread also tackles a version of olpc.fth that'll work for SD cards.

[koolkat]

Yeah  so I figured it out and all is fine.

My error was due to a typo  I had boot-filt instead of boot-file in olpc.fth   silly small keyboard


I was wondering if it was possible to write a boot menu   so instead of having to press down on the rocker it would ask which place to boot from


say something like :
\
\boot menu outputs
\
" press 1 to boot Xubuntu from SD" .
" Press 2 to boot sugar from internal nand" .
" Press 3 to boot alternante image from nand" .
???Some code to get info from the user of a 1 2 or 3 and add it to the stack??
if dup 1 =
{code to boot from sd}
else if dup 2 =
{code for normal boot}
else
{code for alt boot}
then
then
unfreeze
boot
\ end of script


I THINK that would work, except I have no idea how to wait for an input from the user.

Otherwise all is running fine so far  I have a battery monitor as well and the internet is working fine.


Thanks for all the writeups Moo  It was actually fairly easy to follow once I understood that mmcblko is the card and mmcblk0p1 is partition 1 on the card.  So a simple fix would be to have at the beginning:

"To use these instruction for a SD card substitute /dev/mmcblko for /dev/sda and /dev/mmcblk0p1 for /dev/sda1"

These instructions have finally been posted on the OLPC wiki: http://wiki.laptop.org/go/Installing_Ubuntu_using_Compressed_Files

[vblackaby]

The instructions worked like a charm for me.  However, earlier, while I was googling, I saw that you uninstalled the Kernel-Headers but said you left them on the disk.  I didn't see them on the disk after a quick search...  I want to add a modem & it is asking for the Kernel-Headers. 

I was going to attempt to make the package, but THAT generated errors as well (something about me not being in the top level, even though i was inside the OLPC kernel... (at least i think i was)

Can you give me any tips as to where in compressed files it is hidden?

Thanks
Victoria

[moocapiean]

The kernel headers I was talking about (if I'm remembering correctly) were the Ubuntu kernel headers, not the OLPC kernel headers.  So, I don't think they'll do you much good.

I don't think I've ever compiled the OLPC kernel, but if it's anything like the regular Linux kernels, you just need to be in the top level of the source code when you run make.  Hmm, you say you're already there...ok, well, in the top level of my kernel's source code directory, I have:

Code:

arch     Documentation  ipc          Makefile        README          System.map
block    drivers        Kbuild       mm              REPORTING-BUGS  usr
COPYING  fs             kernel       Module.symvers  scripts         vmlinux
CREDITS  include        lib          net             security
crypto   init           MAINTAINERS  patches.txt     sound

Do you see stuff like that if you run ls? You may not see all of that and other things may be there too, but it should look similar.

If you're still having trouble, I can try downloading the kernel sources and see how it goes for me.

Oh, how were you trying to add the modem?  Were you trying to install a driver or some other kind of software?

[vblackaby]

I'm pretty new to this...

I am trying to install a zoom usb modem.  when running the install from either the deb or make,  i get

Code:

When reporting a problem for the first time, please send
us the file generated by "dgcconfig --dumpdiag".

No pre-built modules for: Ubuntu-7.10 linux-2.6.22-20071121.7.olpc.af3dd731d18bc39 i586

so i assume it is looking for this kernel's headers.  i installed the generic ones and no dice..

i was following the directions on a Ubuntu site... i don't have the link on this machine... but i was using...
fakeroot make-kpkg --initrd --append-to-version=-custom kernel_image kernel_headers



on both the root directory and inside /lib/modules/2.6.22-20071121.7.olpc.af3dd731d18bc39/kernel

there was nothing in my /usr/src (after installing generic headers they're there)

---edited---

ok - it was late and i was being an idiot.  I found the kernel directory...  but the fakeroot command still isn't working.  I am going to try to use the diskimage technique... i need to get something up asap - then i will come back and figure this out.

[Brian Basgen]

 Strange. I'm getting an error. After I've downloaded the compressed file, and try to decompress in /mnt; I get a bunch of errors. When I try to ls into OLPCRoot, I get a "Input/output error".

 Perhaps something went wrong with the format of my disk.... hmm...

[moocapiean]

vblackaby:

The fakeroot command may not be working because it isn't installed.  Try running sudo apt-get install fakeroot in a terminal to get the program, then running the command you were trying.  Good luck!
