[edit] Introduction

This release has been developed and tested in the following environment.

OS Kernel: Linux® 2.6.29.
AndroidTM Donut public project.
Toolchain: CodeSourcery compiler version 2008q3-72.

[edit] Release Content

The release refers to the source code in git trees and the binary packages are distributed in different projects. The next section on how to build will help pull them into the correct directories to integrate the software system.

Documentation
OMAPpedia is an excellent source for details on the various components. There is a project listing in the main page on the various components.

Source code
Release Manifest for open code source. Release Tag - RLS25.12

Other Binary packages

DSP Binary Package - DSP binaries Connectivity Package - Wilink project

[edit] 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 RLS25.12 Package. Please follow the below instructions to modify the file system to make it work.

RLS25.12 when built from the release tag may not boot without some DSP binaries. You should be able to boot if you rename /system/lib/libskiahw.so to something else without requiring any DSP components.

It's the JPEG decoder that's looking for rmproxy, since resource manager is enabled in this release which requires qosdyn_3430 and baseimage. Doing this will enable the sw codec and boot will work without needing any DSP components. These are available as part of the DSP package and can be used from that to boot without the above procedure.

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

Connectivity package

Connectivity package can be obtained from Wilink project. For instructions to build and test, refer to Wilink wiki

• PPM SmartReflex™
  • SmartReflex™ is an adaptive voltage scaling technology, in which the supply voltage can be adapted to the silicon performance either from the static sense (e.g. adapted to the manufacturing process of a given device) or the dynamic sense (e.g. adapted to the temperature induced current performance of the device). This allows dynamically adapting the VDD1 & VDD2 voltages to the silicon characteristics and temperature to minimize active power consumption. It can operate under manual or automatic mode to suit PM SW needs. Though it is recommended to run the system at specified voltage & frequency as per selected OPP, the optimal voltage for a given frequency varies with the manufacturing process of the device and temperature. Thus, the optimal voltage for a given frequency is different for every silicon chip based on its silicon characteristics (hot vs. cold samples) and current temperature.
    
    Note: SmartReflex™ does tuning around the recommended OPP voltage and never changes the OPP
    
    To enable/disable SmartReflexН for VDD1 & VDD2, use the following commands, respectively:
    # echo –n > /sys/power/sr_vdd1_autocomp
    The value can be
    0 – To disable
    1 – To enable
     
    # echo –n > /sys/power/sr_vdd2_autocomp
    The value can be
    0 – To disable
    1 – To enable

  [edit] Limitations/Known Issues

  AV playback frame drops while playing a high bit rate clip

  Disable deblocking while running clips with resolution higher than #x480 or 480x# (D1) Set on the terminal the following flag:
  setprop deblocking.video.disableIfD1 1
  To clear the flag if it has already been set:
  setprop deblocking.video.disableIfD1 0
  

  Random white screen issue

  This is a known issue which happens due to change in GPIO pin muxing in beta and production boards. Reading the gpio_94 to determine production vs pilot units has shown not to be a reliable method. Now we will check the silicon version of the zoom2 unit based on the following:
  
  If Silicon rev is ES3.1 or greater => Zoom2 Production Units. If Silicon rev is ES3.0 or lesser => Zoom2 Pilot Units
  
  With this information we can determine the gpio value required for the lcd reset:
  
  Zoom2 Production Unit => LCD panel reset gpio = 96
  Zoom2 Pilot Unit => LCD panel reset gpio = 55
  
  Refer to the commit ID 571770a16d95a0eaae9740ee0c58246700b345c7 for a fix.
