Detailed InstructionsEdit

It is assumed that the development environment has been set up.

• start the Linux development VM and login into the system
• open a terminal window and cd into U-Boot source code

cd axel/u-boot

• in case of needs you can update your local repository with the following git command

git pull

• configure the build environment

source ~/env.sh

• enter the source tree directory and run the following commands:

make mx6dlaxel_defconfig
make

NOTE: this is the default configuration suitable for latest Axel Dual Lite.

The former command selects the default XELK configuration suitable for latest Axel targets (for additional defconfig please refer to the U-Boot defconfigs table above), while the latter builds the U-Boot binary image itself (u-boot.imx).

u-boot.imx can be copied to the tftp root directory /tftpboot/axel/ with the following command:

cp u-boot.imx /tftpboot/axel/
