Announcing an OpenFirmware-based Power Log Collector
http://wiki.laptop.org/go/Power_Log_Collector#OpenFirmware How to prepare a bootable USB drive for collecting power logs from multiple XO-1, XO-1.5 and XO-1.75. Note: not widely tested. It uses OpenFirmware functions to write files to USB drive, and in the face of minor filesystem corruption these functions have been known to make the corruption far worse, to the point of losing files. Testing of FAT filesystems is especially needed, with an image of the filesystem taken before running the program. Recently verified FAT filesystems have not shown any problem. -- James Cameron http://quozl.linux.org.au/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: XO1/os31 update-nand issues
Don't use update-nand on XO-1 against a non-partitioned image. Once a signed build becomes available, the instructions should be changed to using the four-game-key method of starting the process, without any typing required. I myself keep several build versions on one (large) USB stick, so I do need to type - to indicate which build version I'm installing. I've been going by the filename-extension -- using 'copy-nand' for .img and using 'update-nand' for .onu -- but I was surprised to have to use 'copy-nand' with the 12.1.0 os5 for XO-1 -- 'update-nand' told me the file length was incorrect. mikus p.s. James - I have a weak XO-1, on which I often needed to redo an attempted install (because fetching the data off the USB stick happened to experience a file read error). Mitch Bradley came up with a timing change in q2e46a.rom which in my testing made 'copy-nand' run smoothly on that weak XO-1. I noticed that with one of this year's q2f roms that I again had to redo 'copy-nand' on that weak XO-1. Did the q2e46a change ever make it into the q2f roms ? ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: coding 88W8388 firmware
Excerpts from John Watlington's message of 2012-03-22 03:27:14 +0100: We did pay to get a version of firmware developed for both the 8388 and the 8686 which offloads the packet processing to the main processor (normally much of this is done by the WLAN's processor). This thin firmware, while consuming more power does allow open source support for 802.11s and AP mode as well as open experimentation with mesh routing and protocols. See http://wiki.laptop.org/go/Thinfirm_1.5 and http://wiki.laptop.org/go/Libertas_Thinfirmware_HOWTO It's worth noting that while libertas_tf exists, it has never been upstreamed and isn't maintained in any way. Fixes to libertas that apply to libertas_tf as well don't get ported. I'm afraid that except maybe for a few special cases it isn't very useful in this state. It's sad to see this useful code rot away. It still requires proprietary firmware, but at least you can use it for AP mode and 802.11s (not to be confused with the OLPC mesh protocol that was based on an early draft of 802.11s and isn't interoperable with anything else). And maybe it's easier to port Thinform to a different operating system (on the libertas chip) than to port the full-MAC firmware. I had forward-ported the libertas_tf patch set to Linux 3.1 some time ago and even ported a few libertas fixes to libertas_tf, but there are still some issues and I don't have any time left to work on it. If anyone is interested in picking this up, I can publish the patches.

I'm specifically asking because recent kernels don't like my SD card (only one in about twenty or fifty boots succeeds; two different failure modes), so I'd need to make sure I diagnose and fix that before upgrading OFW the next time.

Re: New boot animation for 12.1.0
pps. Richard - when the pretty boot appears to stall, I do not think booting has gotten very far. Without both USB devices plugged in, pretty boot eventually activates the camera LED (presumably while initializing the camera). But when pretty boot stalls (with both USB devices plugged in), I did not see the camera LED ever being activated. [BTW, whenever booting completes and the system is up. powerd *is* running.] ok.

Re: XO1/os31 update-nand issues
On Mon, Mar 26, 2012 at 09:45:25AM -0500, Mikus Grinbergs wrote: Don't use update-nand on XO-1 against a non-partitioned image. Once a signed build becomes available, the instructions should be changed to using the four-game-key method of starting the process, without any typing required. I myself keep several build versions on one (large) USB stick, so I do need to type - to indicate which build version I'm installing. Yes, that use case is not well supported and it could be improved. The Australian deployment improved it by adding a boot procedure on the USB drive, in boot/olpc.fth, which checks for certain conditions and perhaps asks questions. It has been a while since I reviewed it. In your situation, you might benefit from a boot menu that offers to install each of the compatible builds it finds on the USB drive. It would only be used on unsecure laptops. Is that interesting? I've been going by the filename-extension -- using 'copy-nand' for .img and using 'update-nand' for .onu -- but I was surprised to have to use 'copy-nand' with the 12.1.0 os5 for XO-1 -- 'update-nand' told me the file length was incorrect. I have not tried 12.1.0 yet, but you should use whatever method the release engineer recommends. p.s. James - I have a weak XO-1, on which I often needed to redo an attempted install (because fetching the data off the USB stick happened to experience a file read error). Mitch Bradley came up with a timing change in q2e46a.rom which in my testing made 'copy-nand' run smoothly on that weak XO-1. I noticed that with one of this year's q2f roms that I again had to redo 'copy-nand' on that weak XO-1. Did the q2e46a change ever make it into the q2f roms ? Since q2e46a was not a controlled release, I don't have any record as to which SVN commit (if any) went into it, sorry. The first mention of q2e46a in mail was from you on 23rd October 2011, and you were quoting a message from Mitch, saying it was on 10/11. The nearest USB related change was svn 2591, http://tracker.coreboot.org/trac/openfirmware/changeset/2591 And yes, this is in the q2f series, though there may have been other changes since. -- James Cameron http://quozl.linux.org.au/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Hola German, gracias por responder.
Y Respondiendo a tus dudas:
1. Me refiero al tratar de acceder ejemplo a schoolserver.escuela(dominio)
en el navegador
2. Conectandome a la red del Router
3. Si lo deshabilito en el servidor para el que se encargue de asignar las
direcciones DHCP sea el router
4. Si, pero vi que es una version todavia un poco inestable y con menos
documentacion asi que preferi usar la ultima version estable.
Lo que quiero hacer es que el router va hacer de AP este asignando las
direcciones y que las XOs se conecten a la red del router como si fuera la
de un AP, el problema son las configuraciones del router ya que son un poco
cerradas ya que son de un proveedor muy utilazado en Mexico, esto lo tengo
que hacer porque van a tardar un rato en llegar los APs
