Suggestions for you to try ... - try a longer time without battery or external power, How long is longer? overnight? - check that the AC adaptor is plugged in, in case the battery is failing to provide enough current to start things up, When I re-flash and first boot I always have AC plugged in case of a FW update or battery failure What model XO-1.5 is it? I believe is a production machine (C2?) On first boot it froze about 4sec into the boot process, I think at loading mass storage devices or something relevant. I'm not familiar with that message. Could you explain further from your memory of the event what else was present? On my first boot I start with the check mark pressed so I can see what's going on. So it was at the boot console. I can not recall the exact message. Was something about mass storage devices but not quite remember. 4.x sec into the boot process. Did not look like the zero dot freeze because the camera light was not on. On hard reboot (with power button for 5sec) ... I hope you didn't do this during a firmware reflashing. That would be bad. No I didn't. Actually I was surprise that was no FW update. My XO-1.5 had q3a39, but the latest is q3a41. Is os205 using q3a39? (ok, I can find that :) Should I be sending it back for diagnosis if everything else fails or just consider it random failure? -- James Cameron http://quozl.linux.org.au/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: [Sugar-devel] Restoring the journal from an 0.82 image

But I'd would like to restore the 0.82 journal to the new configuration, is the journal format in 0.82 compatible with 0.88?, to try to backport the backup/restore scripts to the 0.82? At the moment, I'm loop(mtdblock and block2mtd ) mounting the 0.82 image, but I haven't figured out how to copy the journal. Hi Luis, if you replace ~/.sugar/default/datastore with the contents of the 0.82 journal it should update it to the new DS format on reboot. If it doesn't, it is a very important bug to report.

NOW! Contributors Program Mtg (#olpc-meeting, 2:30PM Boston Time, Friday)
Please all join us right now reviewing the latest OLPC/Sugar community projects over IRC Live Chat: http://forum.laptop.org/chat Then type at bottom: /join #olpc-meeting AGENDA: * Fast Review of the 6 latest (greatest!) HW/Project Proposals -- please join us advocating for, and/or reviewing shortcomings of these proposals: 1. SaigonOLPC - Somerville, Massachusetts Vietnam 2. Columbus School for Girls requesting broken XOs for parts - Ohio 3. OLPC Bahamas 4. Amadou Basse Sall Primary School OLPC Edu Prjct - Dagana, Senegal 5. Lap-Swap: Integrating Technology for Education - Tempe, Arizona 6. Ntugi/UCC: Kenya, Canada * Which projects might you enjoy Mentoring below?! http://wiki.laptop.org/go/Projects http://rt.laptop.org/Search/Results.html?Query=Queue=%27contributors%27 * New projects libraries -- teaching them Community Outreach: http://wiki.laptop.org/go/XO_Laptop_Lending_Libraries 1. SaigonOLPC - Somerville, Massachusetts Vietnam http://saigonolpc.wordpress.com http://rt.laptop.org/Ticket/Display.html?id=63763 [SPECIFIC SITE NEEDS TO BE POSTED OFF http://wiki.laptop.org/go/Projects ] Requests 2 XO-1.5s over 2 months Project Objectives: Improve children’s education and their skills at Ba Chieu Shelter in Saigon. Phase two is needed to follow up on how actively girls are using the Xos and how much should be taught to them to make them feel comfortable to sue XO in everyday life. Ba Chieu Shleter is a role model for other Shelter in the city It is a pilot project in the South of Vietnam, a part of Vietnam OLPC project. This project is important in building OLPC community and raising awareness of Open Source Software and XO laptops 2. Columbus School for Girls requesting broken XOs for parts - Ohio http://rt.laptop.org/Ticket/Display.html?id=63782 [SPECIFIC SITE NEEDS TO BE POSTED OFF http://wiki.laptop.org/go/Projects ] Requests ? XOs Project Objectives: The main objective of this project is to interest and engage high school girls in computer science through this hands-on, real-world, socially relevant service learning project. Our school typically only fields 2-3 students in any given computer science class we offer, and they are always the same 2-3 students. This project attracted over 40 students initially, which is almost 15% of our student body. The service learning trip is the “hook” I needed to interest many students in something they might not otherwise discover. By all accounts, our first trip was a phenomenal success, with many girls now interested in pursuing programming or other computer science work. This second year, I will require more hardware work from the students, so these broken laptops will help provide the equipment I need. 3. OLPC Bahamas http://olpcbahamas.blogspot.com http://rt.laptop.org/Ticket/Display.html?id=64038 [SPECIFIC SITE NEEDS TO BE POSTED OFF http://wiki.laptop.org/go/Projects ] Requests 2 XO-1.5s over 3-4 months Project Objectives: We have a serious lacking in the area of education here in the Bahamas. Our national average is a D+. I want to promote education through technology and give the Bahamas a new industry of computer savvy people working with technology and bringing us as a country into the 21st century. 4. Amadou Basse Sall Primary School OLPC Edu Prjct - Dagana, Senegal http://rt.laptop.org/Ticket/Display.html?id=64118 [SPECIFIC SITE NEEDS TO BE POSTED OFF http://wiki.laptop.org/go/Projects ] Requests 30 XOs over 24 months Project Objectives: - Provide school children with access to computer understanding and usage - Use computers for pedagogical purposes - Stimulate exchanges with another local school as well as enhance the current pedagogical cooperation with a French primary school based in Britanny (29920 Nevez France) Headmistress: Mrs Dominique Puloch - Capitalize on computing skills of one of the schools’ head masters who will train the school teachers - Take advantage of the existing limited computing infrastructure: 4 PCs with internet access - Involve pupils’ parents through allowing the children to bring XOs home for their homework - Stimulate Information exchanges within the local community*: town administration, welfare center… on topics related to nutrition, health: protection against malaria, schistosomiasis or vision deficiencies. These diseases are a major issue in the region and lead amongst other problems to school absenteeism. - Helping families suffering from poverty and low education level with administrative tasks, making XO an essential tool: The children, with the help of their school teachers, will help the family write a letter or a request for example. The draft could be sent through the Internet, thanks to the PCs we have. 5. Lap-Swap: Integrating Technology for Education - Tempe, Arizona

Clocks on XOs
Was: Subject: =?ISO-8859-1?Q?Caacup=E9?= war bullettin -- day 1 ber...@codewiz.org said: * Date not being updated One laptop booted with clock set to the Epoch. Is that one of the old XOs that had troubles with the tiny battery feeding the TOY/RTC clock when the main battery and wall power are both disconnected? I forget the details, but I think there was a problem with the battery holder. Oddly, the lease was accepted anyway. We need to figure out why the clock is not being updated from the network. NetworkManager used to call ntpdate when it setup a connection. Was that an OLPC addition? I think this area gets tangled up with security and lease checking. Do we want/need two separate modes, one for the secure case and another for developers without a school server? What are the school servers doing to keep their clocks reasonable? Why aren't we using ntp? ntp is probably overkill for XOs. Besides, who would want to give up that much ram? On top of that, ntpd doesn't get along with power saving mode. Aside from quirks like this one, is time on the XO normally good enough? -- These are my opinions, not necessarily my employer's.
