as far as I remember:
ramdisk.img contains a small initial root file system used to boot the
system
system.img contains the filesystem containing all system files (including
system libraries and system apps)
userdata.img contains the initial content of the /data partition
there are no application
I got to know that in Android OPEN_GL ES is configured by default for
software thats why it uses the software packages of android. How I can
configure the OPEN_GL ES for hardware. Is it just a case of replacing
the "android/out/target/product/generic/system/lib/libGLES_CM.so" with
a new one build
I managed to make Android build the libaudio shared library (taken
from omapzoom.org), which was then put where it should be in /system/
lib/. I also have BOARD_USE_GENERIC_AUDIO set to false, which should
make audioflinger use this libaudio instead of the generic
libaudiointerface, but I still ge
I had same problem with you.
But after clean build, audiofligner use the libaudio.
I think that android build system have some weakness.
But I have another problem.
When AudioHardwareOmap::openOutputStream() is called,
snd_pcm_open() is failed. Error message is like 'no device file'.

That makes sense. I will try from a clean build.

Very thanks for your very complete and clear explanation.
To install android on freerunner it was very nice to
have a setup script like for installing debian
on freerunner.
A script that check all and do all the necessary steps
(patch, compile, deploy, ecc)
Why not create an open source project
I don't see any fundamental reason why building FreeRunner images
couldn't be done from within the existing Android build system, and I
believe that the existing configuration system should be able to
exclude parts that might be undesirable (or could be reasonably easily
extended to add that abili
Hi,
are you sure, that you need 3D acceleration to enable those codecs? Or
does your platform offer specialized chips for doing that codec job? I
do not know any OpenGL related stuff, that provides access hardware
codecs, but I am not familiar with OpenGL-ES. Do you know, how you

Hi,
You need to supply "libhgl.so", which must be a regular OpenGL ES
library. libGLES_CM.so, will load it at runtime and defer to it for 3D
h/w acceleration.
implementing your own h/w accelerated libhgl.so right now is very
difficult because Android is not ready for this just yet. this is an

I am very new to android, do you mean that is possible to
download and run make android on a freerunner?
I have downloaded the source code, there are any gb

It is possible to make on pc with target a freerunner

I think isn't easy to make on freerunner direct, there

Sorry, I wasn't very clear. It's not currently possible to run Android
"as is" on a FreeRunner.
I meant that it would be nice to be able to download the official
Android source code on a PC (and nothing else beyond the tools that
are normally needed to compile Android), and to be able to compile
Ok! Understand! I agree with you. It would be nice
to have a script that patch and use the official make
and source code of android to resolve freerunner issues.

Hi Maxime,
I have a OMAP3EVM and I'm interested in porting it with android.
OMAP3EVM come with OMAP35x_SDK_0.9.5 that contain 2.6.22.18.
1- Did you port the kernel to 2.6.25 or just used 2.6.22.18 + android
patch - goldfish stuff ?
2- Did you try to directly use the OMAP zoom on a OMAP3EVM, It
AudioHardwareGeneric tries to open /dev/eac. If /dev/eac fails to open
or respond correctly to I/O requests (read/write,ioctl), the audio HAL
will fall back to AudioHardwareStub which is just a null output driver
that emulates timing using usleep() calls.
You can either write your own implementat
Thanks for your reply.
But I think that you had some misunderstanding about my article.
I now use own implementation which is called AudioHardwareOmap.
You can see them below url.

Is your device show up in /dev? Have you checked permissions? Did you
add your device to the devperms table in system/core/init/devices.c?

Davide,
There are a few fundamental things I'd like to pass along:
First, in order to build Android for the Freerunner it takes very little
effort and the goal is to be able to do so without any modification to
the sources.
Second, there are two components that I use which are not owned by me
thanks Mathias & Markus for your quick responses.
Mathias, currently the system/lib folder doesn't contain the
"libhgl.so" specified by you. Do you mean to say that we have to add
this file extra into this folder so that libGLES_CM.so, will load it
at runtime and defer to it for 3D h/w acceleratio
Also Mathias, i was unable to find any information related to
"libhgl.so", could you please guide me regarding that too. Where i can
get that file?

You are trying to write a driver for hardware you don't have? That
seems... challenging.

There are not information about it at the moment because, as I said,

sorry for some confusing questions. I was supposed to ask the 3D

the things together in the end. but the things is clear that Currently
Android won't support 3D hardware acceleration and its work is in
progress.

I suppose that Android uses the OPENCORE from packet video to do all
the stuffs related to video encoding and decoding. I want to use the
built in capabilities of my processor which provides Standard level
encoding/decoding of multiple content formats including MPEG4, H.263,
H.264. How i will use
You've already figured most of it out. You'll need to check pv.com and
how Packet Video does things. I think they have an SDK to develop
hardware codecs. Then you'll want to modify external/opencore
accordingly to use your hardware codecs.
