Download the SDK

Perform the following steps to download the SDK from the StarFive official GitHub repository.
  1. Check out the SDK repository (for example, branch JH7110_VisionFive2_devel) and check out all of the linked sub-modules by executing the following commands:
    $ git clone git@github.com:starfive-tech/VisionFive2.git
$ cd VisionFive2
$ git checkout JH7110_VisionFive2_devel 
$ git submodule update --init --recursive
    Note: This will take some time and requires around 5 GB of disk space. Some modules may fail because certain dependencies don't have the best git hosting. The only solution is to wait and try again later (or ask someone for a copy of that source repository).
  2. (Optional) For users who build the release tag version, step 1 is enough. For developers who need to switch the 4 submodules (namely, buildroot, u-boot, linux, and opensbi) to correct branch, you can run the following commands. You can refer to the .gitmodule file for the correct branch information.
    $ cd buildroot && git checkout --track origin/<buildroot_branch> && cd ..
$ cd u-boot && git checkout --track origin/<u-boot_branch> && cd ..
$ cd linux && git checkout --track origin/<linux_branch> && cd ..
$ cd opensbi && git checkout <opensbi_branch> && cd ..

    The following are the example commands:

    $ cd buildroot && git checkout --track origin/JH7110_VisionFive2_devel && cd ..
$ cd u-boot && git checkout --track origin/JH7110_VisionFive2_devel && cd ..
$ cd linux && git checkout --track origin/JH7110_VisionFive2_devel && cd ..
$ cd opensbi && git checkout master && cd ..
