How to Build Android 4.2.2 for A20-OLinuXino-MICRO

https://www.olimex.com/forum/index.php?topic=2475.0

I've try to follow this procedure to build my own custom Android image, I'm facing some problems with it.
I wish to post on this thread and figured out that it is LOCKED ...

Send error message please.

[dave-at-axon]

Post your errors here. I've been building the Android OS based on 4.2.2 without any issues so we can try to help you out here now

Hi Dave,

It is not at compile time, but at run time that I get the following error, a crash in audio driver :

Does the rest of the system boot ok and come up or does it exit and restart at this point?

Are you sure that it is inside the audio driver itself or not another one that makes calls to it? I recall something similar in my early builds with the camera driver. I don't us it so I removed the init for the gt2500 etc.

Also, I can't remember how I did it now but there is a way to get the exact line of code that the error appears for. There was some kind of tool that would show you this. I'll see if I can dig it out.

Hi Dave,
Sorry for late reply ...
For the rest of the system boot log, there are no much more, after the dump above, it finalize by doing at CPU halt if I understood :

I've also checked in lichee/linux-3.4/.config, and it seems that the SND_PCM driver is built-in, not as module : CONFIG_SND_PCM=y

I will continue digging with the different versions downloaded, but if I remenber, the lichee-v3.0 was doing the same thing.

Is there anyone who have standard Android image for SD working anf shared ?
The Olimex one was thru obsolete torrent, and they didn't answered to my other post ...

[dave-at-axon]

What is your configuration?

I can try and build you an image. I can build with the resistive touch for the 7" for example.

PM me your email address and I will send you a link to the image once it's done.

[martinayotte]

Hi Dave,
Sorry for the delay...
Mainly, I wish to have Android on SDCard, displaying on HDMI with USB Mouse, and DHCP Networking.
If the image becomes successful, without the previous SND_PCM crash, maybe you can also provides me source snapshot.
(This SND_PCM issue is really strange, I have no clues yet  )
Thanks in advance !
Your help is really appreciated !
