Building Kernel Image

Perform the following steps to prepare the kernel image:

1. Pull the kernel code:

   $ git clone https://github.com/starfive-tech/VisionFive2.git

   • For more instructions, please refer to https://github.com/starfive-tech/VisionFive2.
   • The Debian image version used in this step is starfive-jh7110-VF2_515_v2.5.0-69.

     Link: https://debian.starfivetech.com/

     The corresponding software version is VisionFive2 Software v2.5.0.

     Link: https://github.com/starfive-tech/VisionFive2/releases/tag/VF2_v2.5.0

2. Compile code:
   1. Enter the following directory:

      /VisionFive2/linux/arch/riscv/configs

   2. Use the following file to replace starfive_visionfive2_defconfig.

      docker_config_20230215

      Note: To download this file, you need to register or login to RVspace.
   3. Run ./build_kernel_vf2.sh script under /VisionFive2/work/linux directory.
      Note:

      • Script download address: build_kernel_vf2.sh
        Note: To download this file, you need to register or login to RVspace.
      • You need to change the target path of the script file to your own file path.

      

3. Confirm the generated files after compilation:
   • Under ./VisionFive2/work/boot path:
     • config-5.15.0-starfive-dirty
     • System.map-5.15.0-starfive-dirty
     • vmlinuz-5.15.0-starfive-dirty
     Note: To simplify the later operations, rename the generated files as the following:

     • config-5.15.0-starfive
     • System.map-5.15.0-starfive
     • vmlinuz-5.15.0-starfive
   • Under ./VisionFive2/work path:
     • linux-headers-5.15.0-starfive_5.15.0-starfive-1_riscv64.deb
     • linux-image-5.15.0-starfive_5.15.0-starfive-1_riscv64.deb
     • linux-libc-dev_5.15.0-starfive-1_riscv64.deb
