Thread: Porting audio to S3C6410

I found in a Chinese forum something about porting Android 2.2 to S3C6410 and the audio. So i post here if can help anyone dev 2.2 for I5700.

Android 2.2 source code has been released, S3C6410 run successfully!
Morning in bed with the phone used to open the cnbeta, first of all to see Droid X release, then that is Android2.2 source release!

He immediately jumped out of bed starting repo, compression, ran lab compile passed.

S3C6410 use of generic, replace the previous 2.1 init.rc to the normal load.

The new version of the basic procedures for all the updates to the new version, launch2, gallery3D other, but seemingly tragic ARM11 running speed of a point!

At the same time seemingly with my current kernel is not stable, it is easy to restart the UI.
