    In Ubuntu, you can install the ARM Cross Compiler by doing: 
    sudo apt-get install gcc-arm-linux-gnueabi
    
export CROSS_COMPILE=arm-linux-gnueabi-
  • Others:
    For others, you can download the Linaro cross compiler and setup the environment by doing: 
    wget -c https://releases.linaro.org/14.11/components/toolchain/binaries/arm-linux-gnueabi/gcc-linaro-4.9-2014.11-x86_64_arm-linux-gnueabi.tar.xz
    
tar xf gcc-linaro-4.9-2014.11-x86_64_arm-linux-gnueabi.tar.xz
    
export CROSS_COMPILE=`pwd`/gcc-linaro-4.9-2014.11-x86_64_arm-linux-gnueabi/bin/arm-linux-gnueabi-

Build AT91Bootstrap from sources

This section describes how to get source code from the git repository, how to configure with the default configuration, how to customize AT91Bootstrap based on the default configuration and finally to build AT91Bootstrap to produce the binary. take the default configuration to download U-Boot from NandFlash for example.

Get AT91Boostrap Source Code

You can easily download AT91Bootstrap source code on the at91bootstrap git repository.

To get the source code, you should clone the repository by doing: 

$ git clone git://github.com/linux4sam/at91bootstrap.git

Cloning into 'at91bootstrap'...

remote: Reusing existing pack: 2476, done.

remote: Counting objects: 167, done.

remote: Compressing objects: 100% (167/167), done.

remote: Total 2643 (delta 135), reused 0 (delta 0)

Receiving objects: 100% (2643/2643), 2.06 MiB | 270 KiB/s, done.

Resolving deltas: 100% (1809/1809), done.

$ cd at91bootstrap/

Configure AT91Boostrap

Assuming you are at the AT91Bootstrap root directory, you will find a board/at91sam9x5ek folder which contains several default configuration files: 

at91sam9x5eksd_uboot_defconfig

at91sam9x5ekdf_uboot_defconfig

at91sam9x5eknf_uboot_defconfig

Tips: nf means to read nandflash, df means to read serial flash, sd means to read mmc card.
Tips: linux means to load linux kernel to RAM, android means to load android kernel to RAM, uboot means to load u-boot to RAM, dt means to load dtb to RAM.

You can configure AT91Bootstrap to load U-Boot binary from NAND flash by doing: 

$ make mrproper

$ make at91sam9x5eknf_uboot_defconfig

If the configuring process is successful, the .config file can be found at AT91Bootstrap root directory.

Customize AT91Bootstrap

If the default configuration doesn't meet your need, after configuring with the default configuration, you can customize it by doing: 

$ make menuconfig

Now, in the menuconfig dialog, you can easily add or remove some features to/from AT91Bootstrap as the same way as kernel configuration.

Build AT91Bootstrap

Then you can build the AT91Bootstrap binary by doing: 

$ make

If the building process is successful, the final .bin image is binaries/at91bootstrap.bin .

Build U-Boot from sources

Getting U-Boot sources

Dedicated page on U-Boot wiki: http://www.denx.de/wiki/U-Boot/SourceCode

You can easily download U-Boot source code from Linux4SAM GitHub U-Boot repository :

  • clone the Linux4sam GitHub U-Boot repository 
       $ git clone git://github.com/linux4sam/u-boot-at91.git
    
   Cloning into 'u-boot-at91'...
    
   remote: Counting objects: 219350, done.
    
   remote: Compressing objects: 100% (40142/40142), done.
    
   remote: Total 219350 (delta 175755), reused 219350 (delta 175755)
    
   Receiving objects: 100% (219350/219350), 56.01 MiB | 1.24 MiB/s, done.
    
   Resolving deltas: 100% (175755/175755), done.
    
   $ cd u-boot-at91
  • The source code has been taken from the master branch which is pointing to the latest branch we use. If you want to use the other branch, you can list them and use one of them by doing: 
       $ git branch -r
    
   origin/HEAD -> origin/master
    
   origin/master
    
   origin/u-boot-2012.10-at91
    
   origin/u-boot-2013.07-at91
    
   origin/u-boot-2014.07-at91

   origin/u-boot-2016.03-at91
    
   origin/uboot_5series_1.x
    
   $ git checkout origin/u-boot-2016.03-at91 -b u-boot-2016.03-at91
    
   Branch u-boot-2016.03-at91 set up to track remote branch u-boot-2016.03-at91 from origin.
    
   Switched to a new branch 'u-boot-2016.03-at91'

Cross-compiling U-Boot

Before compile the U-Boot, you need setup cross compile toolchain in the section.

Once the AT91 U-Boot sources available, cross-compile U-Boot is made in two steps : configuration and compiling. Check the Configuration chapter in U-Boot reference manual.

Go to the configs/ to find the exact target when invoking make .

The U-Boot environment variables can be store in different media, above config files can specified where to store the U-Boot environment. 

   # To put environment variables in serial flash:

   at91sam9x5ek_spiflash_defconfig

   # To put environment variables in nandflash (default):

   at91sam9x5ek_nandflash_defconfig

   # To put environment variables in SD/MMC card:

   at91sam9x5ek_mmc_defconfig

Here are the building steps for the AT91SAM9x5-EK board: 

# You can change the config according to your needs.

make at91sam9x5ek_nandflash_defconfig

make

The result of these operations is a fresh U-Boot binary called u-boot.bin corresponding to the binary ELF file u-boot .

  • u-boot.bin is the file you should store on the board
  • u-boot is the ELF format binary file you may use to debug U-Boot through a JTag link for instance.

Build Kernel from sources

Getting Kernel sources

To get the source code, you have to clone the repository: 

$ git clone git://github.com/linux4sam/linux-at91.git

Configure and Build the Linux kernel

Now you have to configure the Linux kernel according to your hardware. We have two default configuration at91 SoC in arch/arm/configs 

arch/arm/configs/at91_dt_defconfig

arch/arm/configs/sama5_defconfig
  • at91_dt_defconfig : for at91sam ARM926 series chips
  • sama5_defconfig : for SAMA5 series chips

At this step, you can modify default configuration using the menuconfig 

$ make ARCH=arm menuconfig

And build the Linux kernel image, before you build you need set up the cross compile toolchain, check this section. 

$ make ARCH=arm

[..]

  Kernel: arch/arm/boot/Image is ready

  Kernel: arch/arm/boot/zImage is ready

Now you have an usable compressed kernel image zImage .

If you need an uImage you can run this additional step: 

make ARCH=arm uImage LOADADDR=0x20008000

[..]

  Kernel: arch/arm/boot/zImage is ready

  UIMAGE  arch/arm/boot/uImage

Image Name:   Linux-4.1.0-linux4sam_5.3+
