Download Firefly_Linux_SDK

First prepare an empty folder to place SDK, better under home, here we
use "~/proj" as example.

Attention:

1. SDK uses cross-compile, so download SDK to your X86_64 PC, do not
download SDK to arm64 board.

2. Build environment needs to be Ubuntu18.04 (real PC or docker
container), other versions may cause build failure.

3. Do not put SDK under shared directory of VM or non-English path.

4. Please get/build SDK as a normal user, root privilege are neither
allowed nor required (except installing sth. with apt)


Install Tools

   sudo apt update
   sudo apt install -y repo git python

Init Code Repository

Method One

Download via repo, you can choose to get full SDK or BSP:

   mkdir ~/proj/rk3588_sdk/
   cd ~/proj/rk3588_sdk/

   ## Full SDK
   repo init --no-clone-bundle --repo-url https://gitlab.com/firefly-linux/git-repo.git -u https://gitlab.com/firefly-linux/manifests.git -b master -m rk3588_linux_release.xml

   ## BSP (Only include some basic repositories and compile tools)
   ## BSP includes device/rockchip, docs, kernel, u-boot, rkbin, tools and cross-compile toolchian
   repo init --no-clone-bundle --repo-url https://gitlab.com/firefly-linux/git-repo.git -u https://gitlab.com/firefly-linux/manifests.git -b master -m rk3588_linux_bsp_release.xml

Method Two

Download Firefly_Linux_SDK sub-volume compressed package:

Linux SDK

After downloading, verify the MD5 code:

   $ md5sum rk3588_linux_release_20230114_v1.0.6c_0*
   c3bcb3f92bd139f72551c89f75d39bfa  rk3588_linux_release_20230114_v1.0.6c_00
   ebb658571a645d4af1e2b569709480b7  rk3588_linux_release_20230114_v1.0.6c_01
   9761cc324e9f7133500b590c441b0307  rk3588_linux_release_20230114_v1.0.6c_02
   7adc9fe2158d7681554dce1def238f49  rk3588_linux_release_20230114_v1.0.6c_03
   3d9201e3849b8a523c05920bebe28b39  rk3588_linux_release_20230114_v1.0.6c_04
   6faaee006fe60fc9be60a64a01506cb6  rk3588_linux_release_20230114_v1.0.6c_05

After confirming that it is correct, you can unzip:

   mkdir -p ~/proj/rk3588_sdk
   cd ~/proj/rk3588_sdk
   cat path/to/rk3588_linux_release_20230114_v1.0.6c_0* | tar -xv

   # export data
   .repo/repo/repo sync -l

Sync Code

Execute the following command to synchronize the code:

   # Enter the SDK root directory
   cd ~/proj/rk3588_sdk

   # Sync
   .repo/repo/repo sync -c --no-tags
   .repo/repo/repo start firefly --all

You can use the following command to update the SDK later:

   .repo/repo/repo sync -c --no-tags
