Port Android Ice Cream Sandwich to Pandaboard(TI OMAP4460)

by mammar

Hi, I am a newbie to porting and currently learning embedded systems with interest in Android. So i thought it would be good learning if port Android Ice Cream Sandwich to Pandaboard(TI OMAP4460). Note: I know that Android Ice Cream Sandwich is already ported to Pandaboard but as i am a newbie so i want to learn the things from scratch to strengthen my skills. https://wiki.linaro.org/Platform/Android I started from the above link to see how can i start porting android to a board. The link below gives the steps to get android source code from https://android-build.linaro.org/. But there are lots of builds on https://android-build.linaro.org/ and i don't know which should i get for my pandaboard. https://wiki.linaro.org/Platform/Android/GetSource I also followed the link below https://wiki.linaro.org/Platform/Android/PortingToNewBoard but the git clone git://android.git.linaro.org/platform/manifests.git gives the following error Initialized empty Git repository in /home/ma/android/manifests/.git/ fatal: The remote end hung up unexpectedly Can someone kindly guide me in the right direction so that i can download and build the right code for my pandaboard and make further changes in the Android ICS code for pandaboard. Any sort of help will be greatly appreciated. Thanks.

RE: HELP - Cannot boot Origen Board

by Andrew Fraser

In response to your questions: The .img file came from Origen/Insignal website. I also tried with the image you mention but got exactly the same results. The LCD never comes up - no backlight, no display. The SD power LED (LED4) comes on while I see the boot text in terminal then the boot text stops and LED4 goes out. I tried the Ubuntu image as well - similar results, I see output on terminal which stops and LED4 goes off. Again, absolutely no display on the LCD and no ability to log in on the terminal. Thanks for your interest.

I flicked the power switch and pressed SWITCH then POWER and saw the board booting in terminal. However, after a short period of time LED4 turns off and I do not see the LCD light or show the Android screen. Do you mean LCD and Android UI doesn't come up at all or they turned off after some time? The output in terminal is given below. Is my board faulty or have I not flashed the correct image to the SD card ? If this output is all you have got then there is definitely something wrong somewhere. Did you try booting Linaro's Ubuntu images on Origen?

HELP - Cannot boot Origen Board

by Andrew Fraser

I have just purchased an Origen Board - Full Package. I flashed the SD card with igen-ics-gcc46-samsunglt-stable-blob.img and placed it into the SD card slot. I flicked the power switch and pressed SWITCH then POWER and saw the board booting in terminal. However, after a short period of time LED4 turns off and I do not see the LCD light or show the Android screen. The output in terminal is given below. Is my board faulty or have I not flashed the correct image to the SD card ?

[ATT] Gerrit mirroring switches to use push --force by default

by Paul Sokolovsky

Hello, It seems that upstreams we mirror to our Gerrit just love to do history rewriting, so we regularly get stuff like: INFO:./git-gerrit-mirror:=== Processing: git://git.omapzoom.org (2 repositories) === INFO:./git-gerrit-mirror:Pushing in platform/hardware/ti/omap4xxx.git Everything up-to-date INFO:./git-gerrit-mirror:Pushing in kernel/omap.git remote: Resolving deltas: 0% (0/231) ^Mremote: Resolving deltas: 1% (3/231) ^Mremote: Resolving deltas: 1% (3/231) To ssh://linaro-aosp-sync-bot@gerrit-git:29418/kernel/omap-omapzoom.git cf718d5..d3c5467 p-android-omap-3.0 -> p-android-omap-3.0 ! [rejected] p-android-omap-3.1 -> p-android-omap-3.1 (non-fast-forward) error: failed to push some refs to 'ssh://linaro-aosp-sync-bot@gerrit-git:29418/kernel/omap-omapzoom.git' To prevent you from losing history, non-fast-forward updates were rejected That means that we're regularly behind in our mirror. This is not new issue, it was spotted soon after the mirror was launched (i.e. half-year ago), and I proposed to do push --force right then, but so far just run a forced push from time to time manually. Well, I guess it's time to make it automatic. What that would mean? That if you push something to an upstream branch, it will be lost soon, irrecoverably. Note that it's explicitly prohibited per our branch policy to commit anything into upstream branches, all Linaro changes should go into separate branches, named per "linaro*" pattern. And as all changes go thru Gerrit review, I guess there's almost no chance to push something in wrong branch by mistake. Still, I figure I better send a heads-up to remind of all this. (And we're waiting on Gerrit upgrade to enforce branch policy on Gerrit level). https://bugs.launchpad.net/linaro-android-infrastructure/+bug/956950 Thanks, Paul Linaro.org | Open source software for ARM SoCs Follow Linaro: http://www.facebook.com/pages/Linaro http://twitter.com/#!/linaroorg - http://www.linaro.org/linaro-blog

EEMBC AndEBench

by Michael Hope

EEMBC have announced AndEBench, a mixed native/Java benchmark for Android. It's available on the Market. I don't know much more. It seems to be CPU bound and the test names sound a bit like CoreMark. The source is available for license and might be worth the Android guys looking into. The awesome thing is they used the 2012.01 Linaro Binary toolchain release to build the native parts - see the compiler version string in the log :) -- Michael

Gerrit SSH interface status and "SSH API" replacement?

by Paul Sokolovsky

Hello, Now that Google itself doesn't use SSH interface to Gerrit (https://android-review.googlesource.com/ssh_info), does it mean that SSH interface is deprecated, i.e. should other parties consider moving away from it? That apparently would make maintenance schedule less flexible: previously, there were separate "Gerrit admin" role which didn't require "sysadmin" (filesystem-level) access for things like DB maintenance. Another question, is there a replacement for "SSH API" like "gerrit review", "gerrit stream-events", etc.? Well, what we'd need right now is analog of "gerrit ls-projects", i.e. a stable, machine-readable way to get a list of projects in AOSP Gerrit. Any hints?
