Demo based on
NAND boot
SD Card boot

Build Demo packages from source code

Android file system

Get Android

1. Get standard Android source code
This is the same as Android4SAM v2.1 release, please reference: GetAndroid

2. Apply Atmel special Android patch

$ wget
$ tar -zxvf Android-2.3.7_r1.tar.gz
Now you can see a new folder < ANDROID_WORKING_DIR >/device/atmel.

Build Android

Build Android is the same as before:
      $ make clean
      $ source build/
      $ partner_setup sam9x5
      $ choosecombo Device release sam9x5 eng
      $ make

Generate Android Image

The is the same as Android4SAM v2.1 release, please reference: Generate Android Image


The AT91Bootstrap is the same as before. Please reference to: AT91Bootstrap

Linux kernel

Get source code

To get an experimental Android4SAM kernel and running on an AT91 product, please go through the following steps:

1. Download the corresponding Linux kernel, we use 2.6.39 kernel.

$ wget
$ tar xvjf linux-2.6.39.tar.bz2

2. Download the ATMEL's patch and apply it

$ wget
$ tar zxvf 2.6.39-at91-exp.tar.gz
$ cd linux-2.6.39
$ for i in ../2.6.39-at91-exp/*; do patch -p1 < $i; done
$ cd ..

3. Download the Android kernel patch and apply it

$ wget
$ cd linux-2.6.39
$ patch -p1 < ../linux-2.6.39.diff
$ cd ..

4. Download Android4SAM patch and apply it

$ wget 
$ cd linux-2.6.39
$ patch -p1 < ../linux-2.6.39_Android-2.3.7_r1.diff 
$ cd ..
You now have an Android4SAM Linux kernel.

Configure and Build Linux Kernel

Now you need to configure the Linux Kernel for TM4300 support.

$ cd linux-2.6.39
$ make mrproper

1. For NAND Flash boot
Warning, important You need to BuildAndroid before this step, and copy mydroid/out/target/product/sam9x5/root directory to linux-2.6.39 directory or use prebuilt extract it directly root.tgz

$ make ARCH=arm at91sam9x5_android_ubifs_pda_defconfig 

2. For SD Card boot

$ make ARCH=arm at91sam9x5_android_sdcard_pda_defconfig 

3. At this step, you can modify default configuration (Optional)

$ make ARCH=arm menuconfig 

4. And build the Linux kernel image

$ make uImage ARCH=arm  CROSS_COMPILE=<path_to_cross-compiler/cross-compiler-prefix->

After finish successfully, you can find kernel image in: arch/arm/boot/uImage

Warning, important NOTE: Make sure "mkimage" command can be found in your current path, otherwise U-Boot style image cannot be built.

Boot up Android

This is the same as Android4SAM v2.1 release, please reference: Steps of Load Image
