Hi Robert, The Linaro project has a script that started as your setup_sdcard.sh called linaro_media_create. As part of our release process we need to have licenses for our files and since our script is based on yours, your choice of license affects what choices we have. So long story short, your file has no license included so care to add one or just tell us what the license is so we can give our script a compatible if not identical one? Thanks John

Direct link to latest image

by Loïc Minier

Hey folks I'd like to mirror and test the latest build of http://snapshots.linaro.org/10.11-daily/linaro-headless/ but I have two issues with this: * having some kind of direct link to the latest image so that I don't need to parse the HTML to get the latest build; something like /latest/ or /current/ would help here * having a constant name for the data as to be rsync friendly; that is, if the image is named linaro-m-headless-tar-20100923-0.tar.gz and linaro-m-headless-tar-20100924-0.tar.gz the next day, it's hard to convince rsync that the data file from the 24th can be mostly inferred from the contents of the 23th; if it was named linaro-m-headless-tar.tar.gz, I would have no problem Where should I be filing bugs to track these requests, and who should I harass to get these resolved? :-) Thanks! -- Loïc Minier

ST-Ericsson ux500 BSP contents

by Arnd Bergmann

I finally got to this and wrote up a summary of the contents of the ST-E BSP that we are mirroring on the Linaro git server: https://wiki.linaro.org/BSP/ST-Ericsson I did not write up my recommendations of how to proceed, but it should give an idea of the work in front of us/them. Linus, if you see any significant omissions or mistakes, please correct me. Arnd

[PATCH] mx51evk: Fix 2 hours reset issue

by Shawn.Guo＠freescale.com

From: Shawn Guo <shawn.gsc(a)gmail.com> The mx51evk u-boot has an issue that system will get reset every 2 hours. MC13892 has an inside charge timer which expires in 120 minutes. If ICHRG and CHGAUTOB are not set properly, this timer expiration will get system power recycled. Since mx51evk has no Li-Ion battery on board, the patch sets ICHRG in externally powered mode and sets CHGAUTOB bit to avoid automatic charging, so that system will not get reset by this timer expiration. The patch also corrects the bit field definition of register 48 (Charger 0) per latest MC13892 Reference Manual.

maverick-proposed queue freeze

by Jamie Bennett

Hi, According to the Linaro release process [1] the maverick-proposed queue will be frozen tomorrow. After this date no uploads should be accepted for -proposed until the queue unfreezes on 8th November 2010 without consultation with the Linaro release team [2]. The total freeze time will be 12 days. The freeze process was agreed at the platform sprint in Prague and has benefits for both Ubuntu and Linaro. This period should be used to flush the -proposed queue, testing, verifying and promoting to maverick-updates what is currently there. If you have an update that really must be added to the queue in the next 12 days please email the team[3] for feedback. The Linaro Release Candidate images will be created on the 1st November and the images will be verified until Final Release on the 10th November. With your help we can get the -proposed queue flushed and produce rock-solid Linaro images, carrying the great work Ubuntu has done to more ARM based platforms. Regards, Jamie. -- Linaro Release Manager [1] http://wiki.linaro.org/Process/Cycle/PostUbuntuReleaseProcess [2] http://www.launchpad.net/~linaro-release [3] linaro-release(a)lists.launchpad.net

DVI /S Video issues in linaro-m-netbook-efl-tar-20101024-0.tar.gz with Beagle Board XM Rev A3

by Manjunath Singh

Dear All, Looks like something is broken in the new kernel ( Post changes to the bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/663642 ), In the earlier versions of the kernel atleast the S- Video used to work ( tested in Maveric 2.6.35.6-l5 Regular/Non netbook edition ). Now If I pass omapfb.mode=tv:pal omapfb.default_disp=tv .. the xorg exits with with /dev/fb0 no such file or directory ( and ls -l on /dev/fb* confirms there is no files by that name ), I tried omapfb.mode=lcd:640x480 ( and other resolutions ), the X server starts but No out put on the screen / LCD tv thorugh S Video. The DVI port with default options ( and tried with different resolutions as well ) connected through HDMI cable to the TV No output on the display in any Distributions/OS/Kernel I have tried sofar. I understand that Fixing DVI might take some time because there is a HW change in Beagel Board XM A3, However I I would really appreciate if some one point me how to get atleast S Video output till HDMI starts working again. Thanks -- Regards, Manjunath --------------------------------- Miles to go before I sleep... ----------------------------------

Linaro@UDS: dining opportunities out of the hotel

by Steve Langasek

Hey all, If you're like me, you're sitting here at the end of the last session of the day feeling peckish and wondering what's for dinner. Which made me realize that there was no information in the Linaro wiki page about the dinner options here at Linaro@UDS. Sorry about that - let's correct that now! Outside of the Wednesday organized dinner, engineers are free to make their own dinner plans - either here at the hotel, or in town. If you want to have dinner in town, buses are available each evening to take you back and forth to one of several points in and around Orlando that are reasonably central to dining opportunities. I've posted the bus schedule here: https://wiki.linaro.org/Events/2010-10-LDS#Evening%20buses Our local experts have provided us a list of recommended restaurants, available here: https://wiki.ubuntu.com/UDS-N?action=AttachFile&do=view&target=List+of+Rest… Bon appetit, -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.

[PATCH] UBUNTU: SAUCE: ARM: Add DSS2 support for Overo board
