Optimizing OVERLAY handling on android-build

by Paul Sokolovsky

Hello, There were increasing Android build times during last month again (going over 3.5hrs). Yesterday, I re-created the seed, but that didn't improve times match. I did more stats on builds and it turns out that we spend almost 1.5hrs in copying ever-growing overlay collection to the slaves via sluggish CopyToSlave Jenkins plugin. That's issues known for at least half-year, and was in queue for being reworked. I didn't work on android-build closely for few months, but now that I'm back on maintenance, I'd like to start with fixing this long-overdue issue. The idea was to pull all the needed overlay, straight to a slave. The complication here was handling of license protected files. ci.linaro.org had the same issue, and used a script to handle automatic downloads for some time. However, as of now, it was switched to other process and the script git bitrotted with recent linaro-license-protection codebase changes. I took a look at revamping it, but then though that it may be a good idea to use simpler and more explicit process, following closely click-thru usage. So, if you want to use a license-protected binaries in a build, you'd need to specify: ACCEPT_LICENSE=<license_id> Where <license_id> is id under which license is registered in linaro-license-protection. One good way to figure it out is to read the license page at all (well, as HTML source, the id is included in some links). Wording of variable name (as well as of commands in underlying implementation) is also explicit to point that its usage construes license acceptance. I prototypes these changes using https://android-build.linaro.org/builds/~pfalcon/panda-jb-gcc47-tilt-tracki… which is down to 2h10m build time. I'm ready to migrate all builds tomorrow, while we're early in cycle start. Please let me know if there're any issues with approach or proposed migration timeframe, otherwise let's make android-build rock again.

How to configure UEFI to specify the SD card as a boot device

by duqi

Hi, I have tried to boot the android on the versatile express. I have created the SD card according the links： http://releases.linaro.org/13.01/android/images/vexpress-linaro-mp Then I tried update the firmware according this links:http://releases.linaro.org/latest/openembedded/vexpress-lsk/#tabs-4 I set the two switchs to the off(just as both up) and I used the UART0. Now I meet a question about how to configure UEFI to specify the SD card as a boot device. When I give it power ,it does not appear the boot selection menu as expected. Could you give me some advices? Look forward to your favourable reply. duqi.

Running powerdebug on Linaro Android causes kernel crash on Samsung Arndale Board

by Mohammad Merajul Islam Molla

Hello, I ran powerdebug on Linaro Android 14.04 with a custom kernel (config file attached). While exporting gpios, it seems to crash the kernel (detail log attached). I have some printfs, added in powerdebug export_free_gpios() function to assist during log taking. for (i = 0 ; i <= gpio_max ; i++) { char command[50] = ""; printf("exporting gpio: %d\n", i); sprintf(command, "echo %d > /sys/class/gpio/export", i); printf("command: %s\n", command); if ((ret=system(command)) < 0) printf("error: failed to export gpio-%d\n", i); printf("ret: %d\n", ret); } >From log, it looks like while trying to export gpio 8, kernel crash is happening - "Unable to handle kernel NULL pointer dereference at virtual address 00000044" (details in attached log) >From output of /sys/kernel/debug/gpio it looks like gpio 8 is not mapped to any device.

Is this expected? -- Thanks, -Meraj

CTS help?

by John Stultz

Hey Folks, So I'm trying to see about using CTS in my own smoke test for the linaro.android kernel in an emulated environment. I'm curious if anyone has any tips on how to best use CTS? The basic setup seems a bit complex, and once I found the CTS-tradefed, I ran into issues with it rebooting the device and the tcpip adb sessions not being re-established. So I was curious if the scripts Lava uses for CTS testing was somewhere easy to find? thanks -john

Linaro_build_cmd.sh for arndale octa not compiling

by Ricardo jota

Hello all, We've been trying to run the linaro_build_cmd.sh for the arndale_octa and we've stubbed around a couple of errors. I was hoping that someone has come across the same errors and has been successful in compiling android 4.4.2 for the arndale octa. I am compiling on Ubuntu 13.10; the script correctly looks for the ubuntu version, but when apt-get installing, two packages need to be changed: - the uboot-mkimage is now replaced by u-boot-tools in the script - the acpica-tools doesn't exist anymore. I just deleted it from the script - the WITH_HOST_DALVIK=false was added to the script; to avoid the error: 'replace' is not a member of 'std' Once I change the packages (line 47), I run the following script > sudo bash ./linaro_android_build_cmds.sh -m pinned-manifest-ann.xml and end up getting the following compile error from a bunch of generic collection<E> warnings: "cc1plus: all warnings being treated as errors" So, I guess my question is: is there a octa version that compiles successfully, and can it compile in 13.10? Again, any hints on would be very helpful. Thank you, -Jota

installing version 14.04 of linaro

by Chris Sparks

Hello, I have been reading the instructions for installing linaro on my android device. I have a Galaxy Tab 3 7" model that I want to re-purpose and before I completely risk bricking my device, I am trying to assess if this would even work. I see references to Versatile Express which I don't have. Can i use linaro to re-purpose my device? Chris Sparks --- This email is free from viruses and malware because avast!
