+ Linaro Android Mailing List Hi, I guess the best way to get information is to subscribe the mailing list and go through the wiki page: http://lists.linaro.org/mailman/listinfo https://wiki.linaro.org/FrontPage For Android, build page and git repositories list are: https://android-build.linaro.org/ http://android.git.linaro.org/gitweb The TI Panda build can be found here: https://android-build.linaro.org/builds/~linaro-android-member-ti/panda-lin… And the release page is: http://www.linaro.org/downloads/ As you already have a Panda 4460 board, then the 14.03 Android release image can be downloaded from above link in "Developers and Community Builds" section. Hopefully it helps. Thanks. Best Regards Botao Sun On 3 April 2014 08:21, gmail <vipzrx(a)gmail.com> wrote: > hi ! I have a new panda4460, how can i start the learning about android > porting ? >

Samsung Arndale security certificate problem.

by Botao Sun

Hi Vishal, When launching the Browser on Samsung Arndale board to show the default Google web page, a pop-up window says: Security warning There are problems with the security certificate for this site. It can be skipped by clicking "Continue" button though. In logcat, I could see lots of following error messages: Failed to find provider info for com.google.settings This issue doesn't exist on ARM Versatile Express A9 Android. The build I'm using for Samsung Arndale is #386: https://android-build.linaro.org/builds/~linaro-android/linux-linaro-arndal… FYI. Thanks. Best Regards Botao Sun

"device-tree" directory is missing in "/proc".

by Botao Sun

Hi Vishal, Looks like we have more issues popped up, now the "device-tree" directory is missing under "/proc". However, from boot log, the blob had been loaded to Kernel: reading board.dtb 21192 bytes read ## Flattened Device Tree blob at 41f00000 Booting using the fdt blob at 0x41f00000 Loading Kernel Image ... OK OK Using Device Tree in place at 41f00000, end 41f082c7 Starting kernel ... root@arndale:/ # find /proc -name device-tree root@arndale:/ # Full boot log can be found in attachment, and the build I'm using is #386: https://android-build.linaro.org/builds/~linaro-android/linux-linaro-arndal… I'm not sure this is an expected behaviour for Samsung Arndale, and for ARM Versatile Express A9, there is a completed directory and file structure under "/proc", which is "/proc/device-tree/model". FYI. Best Regards Botao Sun

If as the log described, "No GPU support detected", then does it mean that all the graphic work now is done by the dual-core A15 CPU itself? Though the speed for navigation among screens is fast and 0xBenchmark test looks good as well. I may be wrong but in this condition, the board seems can't be considered as "Hardware Accelerated", at least not "GPU Hardware Accelerated". Also, as I know, "Android PixelFlinger" is a software renderer. Do you know more information about this? Thank you. Best Regards Botao Sun

linaro android for help

by dcv

I want to use fastmodel to run a android system.As the document say,it used "vexpressrtsm-ics-gcc46-armlt-stable-open-12.04-release".When I download the source code using the script "linaro_android_build_cmds.sh",there are errors in it. So,I want to know the differences between vexpress-jb- vexpress-linaro-mp- vexpress-lsk- vexpress-linaro- ,and which version can replace "vexpressrtsm-ics-gcc46-armlt-stable-open-12.04-release"? Looking forward to your answer.

Hi Vishal, For the SD MMC test on Samsung Arndale board, the value of EXTERNAL_STORAGE doesn't match with the output of "df": root@arndale:/ # df Filesystem Size Used Free Blksize /dev 1000.6M 164.0K 1000.4M 4096 /mnt/asec 1000.6M 0.0K 1000.6M 4096 /mnt/obb 1000.6M 0.0K 1000.6M 4096 /system 739.9M 371.1M 368.8M 4096 /cache 243.9M 2.0M 241.9M 1024 /data 487.8M 51.4M 436.4M 1024 /mnt/media_rw/sdcard0 5.8G 12.0K 5.8G 4096 /mnt/secure/asec 5.8G 12.0K 5.8G 4096 root@arndale:/ # echo $EXTERNAL_STORAGE /storage/sdcard0 root@arndale:/ # "/storage/sdcard0" is not in the output of "df".
