Instructions

It is assumed that the development environment has been set up properly as described here.

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

cd ~/desk-mx-l/u-boot

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

git pull

• configure the build environment

source ~/desk-mx-l/desk-mx6ul-l-4.0.1_env.sh

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

for the AXEL Ulite EVK

make mx6uldesk_axelulite_defconfig
make

for the SBC platform:

make mx6uldesk_lynx_defconfig
make

NOTE: this is the default configuration suitable for latest <SOM> target.

The former command selects the default DESK-MX6UL-L configuration suitable for latest <SOM> targets (for additional defconfig please refer to the U-Boot defconfigs table above), while the latter builds the U-Boot binary image files (SPL and u-boot.img).

Binary files can be copied to the tftp root directory /tftpboot/desk-mx-l/ with the following command:

cp SPL u-boot.img /tftpboot/desk-mx-l/

Please refer to this page for more information on how to update the bootloader on your board.
