Build and Installation Instructions

Building the Bootloader, Kernel and Android File System

The final Release RC tag from L25x manifest for the source should be used. Perform a clean build of u-boot, x-loader, kernel and the android file system. Instructions on how to build can also be obtained from Android Wiki

Pre-built binaries from this release can be obtained from Package. Please follow the below instructions to modify the file system to make it work.

DSP binaries package

Pull in the DSP binaries and install them following the instructions in the readme.txt in the package. Features supported can be referred at OpenMAX page

IMPORTANT: First you need to rename/move a couple of libraries to make them work. The libraries are in /system/lib:

Rename them to something else (e.g. libOMX.TI.AMR.decode.so.bak and libOMX.TI.AMR.encode.so.bak). By default, AMR libraries have been already renamed in available pre-compiled binaries RLS25.INC2.5 Package.

If you are booting from NAND then once you have booted your filesystem, on your terminal type the following:

cd /system/lib
mv libOMX.TI.AMR.decode.so libOMX.TI.AMR.decode.so.bak
mv libOMX.TI.AMR.encode.so libOMX.TI.AMR.encode.so.bak

then reboot.
