Hi,

We are working on beagleboneblack android TI-Android-JB-4.1.2_AM335x_4.0.1.bin release.

We follow the steps of below link to build the android for beagleboneblack.

http://processors.wiki.ti.com/index.php/TI-Android-JB-4.1.2-DevKit-4.0.1_DeveloperGuide

We are using below command for building android for beagleboneblack.

make TARGET_PRODUCT=beagleboneblack OMAPES=4.x sdcard_build

But, we are getting some errors while build the source of andorid.

1. find: `src': No such file or directory.

2. building the sgx kernel modules...
../common/android/platform_version.mk:141: *** Must build against Android >= 2.0. Stop.

Please suggest why we are getting this errors?

Thanks,
Devang.

Hi Devang,

Android must be built prior to build kernel.
It turns out that the rule sdcard_build will first build the kernel without detecting if Android was built or not.

To workaround this:

1) please build without the sdcard_build parameter first:
$ make TARGET_PRODUCT=beagleboneblack OMAPES=4.x

2) After it built successfully, then build with the sdcard_build parameter
$ make TARGET_PRODUCT=beagleboneblack OMAPES=4.x sdcard_build

Hi,

We tested with command you suggested but still we are getting errors like below.

1. find: `src': No such file or directory
PRODUCT_COPY_FILES frameworks/base/data/sounds/effects/ogg/Effect_Tick.ogg:system/media/audio/ui/Effect_Tick.ogg ignored.

2. In file included from external/webrtc/src/modules/audio_processing/audio_processing_impl.cc:11:0:
external/webrtc/src/modules/audio_processing/audio_processing_impl.h:16:16: fatal error: list: No such file or directory compilation terminated.
make: *** [out/target/product/beagleboneblack/obj/STATIC_LIBRARIES/libwebrtc_apm_intermediates/audio_processing_impl.o] Error 1

Please suggest.

Thanks,
Devang.

Hi Devang,

the missing src should not be a problem. We have the exact same behavior and the process still builds ok.
The second missing file is not normal, you might had a problem when doing the repo sync. You should be able to run the following command to fix this:

$ cd <AOSP root>/
$ repo sync external-webrtc

Hi Adeneo,

We build succesfully android image for beagleboneblack.

But when we give below command for sd card installation.
sudo ./mkmmc-android.sh /dev/sd<sd card mount-point>

We are geting below error.
cp: cannot stat ‘START_HERE’: No such file or directory

Please suggest.

Thanks,
Devang.

Hi Devang,

This START_HERE folder is an optional one that will be copied on the SD Card if it exists, but should not impact the flash of the MMC when it is missing.
Is your SD Card bootable after running this script? in this case, you can safely ignore this error which is actually just a notification.
If this is not booting, let us know, we will investigate.

Hi Adeneo,

Yes, you are right. SD card is bootable. we can boot the beagleboneblack with our build images.

We have one query regarding root the android system.
Can you please tell us how we can do root this android system?

Thanks,
Devang.

Hi Devang,

the serial console should already be root on the prebuilt binaries:
see the console service configuration in init.rc that has the"user shell" commented out.

You can also use the following command "adb root" from the host to root the platform. This is possible since the prebuilt binaries are an "eng" build that set the following properties:
- ro.secure = 0
- ro.debuggable = 1

Hi Adeneo,

We have to add support for rtsp stream in android beagleboneblack. In android package we found some rtsp directories in below path.

./frameworks/av/media/libstagefright/rtsp

Could you please suggest how can we compile same for the beaglebone black and how can we integrate it with in android?

Thanks,
Devang.

Hi Devang,

Yes rtsp is supported by default as suggested by Android website:

http://developer.android.com/guide/appendix/media-formats.html

Therefore you should be able to create your own MediaPlayer to play such stream. You can refer to some CTS tests that include test examples on this transport stream:

http://androidxref.com/4.2.2_r1/xref/cts/tests/tests/media/src/android/media/cts/StreamingMediaPlayerTest.java#28

For any further question, please create a new thread per question in order for people to be able to search through the forum on specific issues.
