Re: [Olpc-france] extend the memory flash space with an SD card to build open80211s
You may want to check out the Debina pages in the Sugar Labs wiki, which tend to be kept reasonably up to date. http://sugarlabs.org/go/Community/Distributions/Debian -walter 2009/3/13 Aime Vareille : > p...@laptop.org a écrit : >> rekik wrote: >> > Hi, >> > >> > I tried to build the kernel open80211s on a group of machines which use >> > ubuntu 8.10 and it's work.

However I found http://wiki.laptop.org/go/Ubuntu_On_OLPC_XO not good because it puts the fedora kernel on the ubuntu which works with some discrepencies ; it takes also some time because of qemu and the boot is not optimal. Today, the stuff with debian on XO is cleaner and very fast to install and test ; http://wiki.laptop.org/go/DebXO is the best page I found about it : # zcat debxo-$DESKTOP.ext3.img.gz > /dev/sdX (for instance, sdb; not sdb1) And update the firmware to q2e34.rom at http://dev.laptop.org/pub/firmware/ Then it works fine either on SD card or USB pendrive of 2 GB minimum and you can still boot and use the native fedora XO build. With SD cards you could need some swap that can be made with a file /swap.bin as explained at http://www.olpcnews.com/forum/index.php?topic=4053.0 However, I have to compile a more recent kernel because the 2.6.25 version on that debian lenny is not sufficient for some of my experiments.

Fedora and Ubuntu use the same upstream source for the kernel.
