Testing Alpha 3 on an Efika MX

by Steev Klimaszewski

Hi All, I saw the release notes for Alpha 3 stating that there was support for the EfikaMX and decided to give it a go. Following the instructions on https://wiki.linaro.org/Releases/MilestoneBuilds . I am using Ubuntu 10.10 on an amd64 dual core Gateway NV52 (laptop.) I've got the linaro ppa added to my system, and I've updated as of 6:33PM CST on Thursday March 3rd. I've got linaro-image-tools 0.4.3-0ubuntu2~linaro1 installed. When I enter the command 'linaro-media-create --rootfs ext3 --mmc /dev/sdb --binary linaro-n-developer-tar-20110302-0.tar.gz --hwpack hwpack_linaro-efikamx_20110302-1_armel.tar.gz --dev efikamx' It spits back linaro-media-create: error: argument --dev: invalid choice: 'efikamx' (choose from 'overo', 'vexpress', 'ux500', 'igep', 'mx51evk', 'beagle', 'panda') Is there a newer version of linaro-image-tools I'm supposed to be using, or am I doing something else wrong? Thanks for any help! -- Steev Klimaszewski <steev(a)genesi-usa.com> Senior Software Engineer, Genesi USA, Inc.

Linking from the Linaro website

by Dave Martin

Hi all, In connection with the recent discussion with the tools guys about how to document the availability of binary toolchains, I wonder whether www.linaro.org really links to the best pages on launchpad, the wiki etc. Keeping these in sync and coherently structured is a maintenance requirement, and we can't expect to eliminate that. But I'm wondering whether we have some way to track: a) HTTP requests with no Referrer b) Pages reached directly from Google or some other search facility (such as the wiki or launchpad search) Pages reached in these ways indicate where developers are using a shortcut and visiting pages directly (I know I do this) or where the page is at least sufficiently hard to find that Google or the wiki search is more efficient (I know I do this too). If we could come up with a list of such pages and frequency of visits, this might give us some interesting information about what we really should be linking to from the main website. It might also help to flag up drift, where activity hotspots move away from the pages accessible from the website over time. Cheers ---Dave

I see With 2.6.36/37+: the console should be changed to 'ttyO2,115200n8' in u-boot. but the problem still exists for me. Could you give some clue for me how to solve this? Thanks. Regards, -Jeremy
