Notes on what is proprietary in the G1 drivers or system(not the applications)

The following infos, although correct, are only valid for Android 1.5. Up to date infos for newer versions of Android (up to 2.2) are available on the Replicant project wiki:

This page contains a detailed table with the non-free low level-related components that are used with the HTC Dream/G1/ADP1, the use of each component and infos about whether the component is crucial, can be avoided or has already been replaced.




I found that howto: http://source.android.com/documentation/building-for-dream,and I've followed part of it,at a point it tells that:

5. in vendor/htc/dream/ there is a script that must be run (from that directory) to extract some proprietary binaries from your device.

Here's what I found:

android@port4 ~/freedroid/vendor/htc/dream $ pwd
/home/android/freedroid/vendor/htc/dream
android@port4 ~/freedroid/vendor/htc/dream $ ls
AndroidBoard.mk     apns.xml        extract-files.sh  htc_dream.mk   kernel          README.txt   trout-keypad-qwertz.kcm  trout-keypad-v3.kcm  vold.conf
AndroidProducts.mk  BoardConfig.mk  h2w_headset.kl    init.trout.rc  kernel.version  system.prop  trout-keypad-qwertz.kl   trout-keypad-v3.kl   wlan.ko
android@port4 ~/freedroid/vendor/htc/dream $ vim AndroidBoard.mk 
android@port4 ~/freedroid/vendor/htc/dream $ cat README.txt 

---- build configuration ----

You can configure to build for HTC Dream (aka T-Mobile G1) by putting
the following in your buildspec.mk file at the root of the source tree:

TARGET_PRODUCT := htc_dream

If you wish to override the included prebuilt kernel image, add:

TARGET_PREBUILD_KERNEL := /path/to/kernel/arch/arm/boot/zImage

---- proprietary files ----

The HTC Dream device includes a small number of proprietary binary 
files that are necessary for Android to work correctly on it.

They can be obtained from your Dream device by running the
extract-files.sh script in this directory.  It will create the 
proprietary subdirectory, and use adb (which will need to be in 
your path) to copy the files from your device.  You will need to
enable USB Debugging (under Settings/Applications/Development)
for this to work.

android@port4 ~/freedroid/vendor/htc/dream $ cat extract-files.sh 
#!/bin/sh
