Instructions

It is assumed that the development environment has been set up properly as described [[DESK-{{{kit-code}}}-L#Quick_start_guide|here]].

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

cd {{{kit-repo}}}/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 {{{kit}}}_defconfig
make

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

The former command selects the default DESK-{{{kit-code}}}-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/{{{kit-repo}}}/ with the following command:

cp SPL u-boot.img /tftpboot/{{{kit-repo}}}/

Please refer to [[Standalone_boot_(DESK-{{{kit-code}}}-L)#Storing_boot_images_...|this page]] for more information on how to update the bootloader on your board.
