The various branches available here will configure at least one build setup for the appropriate branch in each repository and clone them into the working directory. If this is not the main branch, see below for build commands.
See the arm64-multiplatform repo for some of the mainline kernel branches tested.
Select the build branch for your board using the github branch button above, which will select the correct branches and repos for the board/SoC family.
Install the base build requirements for your board. On Ubuntu focal, it would be something like this:
- aarch64 cross toolchain:
apt-get install gcc-8-aarch64-linux-gnu flex bison build-essential - arm cortex-M cross toolchain:
apt-get install gcc-arm-none-eabi - <additional board-specific dependencies>
Since this is a u-boot branch for 64bit raspberrypi variants, the following graphic should illustrate where u-boot fits in the overall boot flow:
Follow the steps in the readme for the branch you select, then use the same branch name with the "repo init" command. This will checkout the corresponding branch HEAD commits on the configured branch for each repository.
You can get status and more using the repo command in the top level directory
once you've run the repo init and repo sync commands. Try:
$ repo info $ repo show $ repo status
See the default.xml file for repo and branch details.
$ mkdir ~/bin $ curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo $ chmod a+x ~/bin/repo
$ PATH=${PATH}:~/bin
$ mkdir <your_board_name>-build
$ cd <your_board_name>-build
$ repo init -u https://github.com/sarnold/u-boot-ATF-manifest.git -b <board_branch>
$ repo sync
Uses the YAML config .repolite.yml to manage git repos and the
tox.ini file to setup the env and execute commands. We also follow
the latest configuration in the TFA platform and u-boot docs in
the steps below.
Note
The TFA support is not yet integrated with this build.
As long as you have git and at least Python 3.6, then you can install and
use tox. After cloning the repository, you can run repolite --sync
via the tox command. It will build a python virtual environment with
all the python dependencies and run the specified commands, eg:
$ git clone https://github.com/sarnold/u-boot-ATF-manifest $ cd u-boot-ATF-manifest/ $ git checkout rpi64 $ tox -e sync # install deps, clone/checkout repositories $ ls ext/ u-boot firmware
To build u-boot for 64bit rpi variants, run the following tox commmand:
$ tox -e uboot
The above build command has CPUS=4 as the default, and can be changed via an environment variable:
$ CPUS=8 tox -e uboot
Eventually, the console display should look something like this:
