Any work arounds, or do I have to go out and get a SDHC reader?

# yum install isomd5sum squashfs-tools
The following is now on the SD card:
 
* the volume name I set with mkfs.msdos
 
* /.olpc.store directory and contents (not relevant to this, but shows card is ok)
 
* empty /LiveOS directory
 
* /syslinux directory with ldlinux.sys in it
 
  
Should the live image simply be copied to /LiveOS? I've never done this before, so I don't know what correct looks like. [[User:Rmyers7|Rmyers7]]

Which I did. This did not resolve the 'No such File' errors. Probing deeper in the script. It seems to be failing on trying to mount a squashfs image. I loaded the squashfs-tools, but I suspect that the real issue is that the XO doesn't have squashfs support compiled in.

So the bottom line is that you can't uses an XO to self install this image.

[[User:jlaska]] - To address the ''No such file messages'' it appears you'll need to install some missing packages.  Try: <pre># yum install isomd5sum squashfs-tools</pre>

Also, what type of system are you running the script on (Fedora8, Fedora9, Fedora10)?
 
 
 
 
 
Thanks for the response. I'll try that. I saw the isomd5sum error, but as it seemed to me just to be just a warning for the checksum, I  ignored it. I'm trying this on an XO with build 767, which is Fedora 9. My other linux box is Fedora 8. I'm going to try to do the  installation on a 2Gb SD card on the Fedora 8 box. If that succeeds at least I'll know what success looks like. I didn't try this before as the 2Gb card I have handy is formatted ext2. But I looked at the script and see that it works with ext[23] as well as fat. [[User:Rmyers7|Rmyers7]]
 
 
 
I did the installs and behavior changed, but I still get errors. I'm now trying to more fully understand the installation script to figure out where the issue is. However, I'm trying another tack - with its own issues. See my other section 'Am I missing something?' [[User:Rmyers7|Rmyers7]]
 
 
 
Probing deeper in the script. It seems to be failing on trying to mount a squashfs image. I loaded the squashfs-tools, but I suspect that the real issue is that the XO doesn't have squashfs support compiled in. As such I figure that we can't self install. I guess its a a trip to the local BB tomorrow to see if I can find a SDHC reader. [[User:Rmyers7|Rmyers7]]
 
 
 
== Am I missing something? ==
 
 
 
I'm trying to get this going. My current tack is not quite following the script, so I don't know if that is the issue. However, I get to a point where there seems to be some information missing here.
 
 
 
===What I did/where I'm at===
 
I don't have a SDHC reader, and haven't run out to get one yet.  I'm trying to do the install on a 2Gb slow SD card, just as a proof of concept. The card is formatted ext2, and has about 200Mb on it that I chose not to scrag - as the info here implies that the card need not be dedicated.
 
 
 
I ran the livecd script and the final results were a filled SD card with a 1.7G image at /LiveOS/ext3fs.img. Is this correct - does the image fill all available space, or did I run out on a 2G card?
 
 
 
The XO has a developer key and security is disabled.
 
 
 
===Something missing===
 
So now I have a card with an image (good???). If I insert it and on powering up, the XO simply powers up normally. If I interrupt the boot, there doesn't seem to be anything to point to for an alternate boot. 'boot sd:\LiveOS\ext3fs.img' doesn't work. There are no instructions here as to how to actually start the F10 image. How does one get into it? [[User:Rmyers7|Rmyers7]] 00:14, 6 November 2008 (UTC)
 
 
 
=== self answered ===
 
Image is not good because we ran out of space.
 
 
 
The unsquashed image is 3Gb, so it looks like about 3.6Gb is needed to install. However the livecd script doesn't report a problem because the squashed size is 700Mb, givving a bougs guess of 1.3GB needed.
 
 
 
And because the image never completed, the forth boot file never gets copied.

Can't self install on XO

I recently purchase a Sandisk SD card to try to do the Fedora 10 installation on my XO. I could not follow the installation instructions as I have an older SD card reader that will not recognize the 4Gb SDHC card.

So, I tried to do a self installation procedure on the XO. I copied the F10 live image to a USB stick, and inserted it and the SD card in thee XO. I downloaded the live iso script and attempted to run it. This failed with lots of 'no such file or directory' errors. The 'already set up' error is because this log was a second attempt, so that I could capture the log. Log follows:

bash-3.2# bash livecd-iso-to-disk.sh --xo --overlay-size-mb 320 --swap-size-mb 256 /media/PNY4/Fedora-10-Snap3-i686-Live/F10-Snap3-i686-Live.iso /dev/mmcblk0p1

  1. yum install isomd5sum squashfs-tools

Which I did. This did not resolve the 'No such File' errors. Probing deeper in the script. It seems to be failing on trying to mount a squashfs image. I loaded the squashfs-tools, but I suspect that the real issue is that the XO doesn't have squashfs support compiled in.
