How to build bsp

1. Install dependencies​

  • on Fedora
$ sudo dnf install autoconf automake curl python3 libmpc-devel mpfr-devel gmp-devel gawk bison flex texinfo gperf libtool patchutils bc openssl dkms libudev-devel golang-bin zlib-devel qemu-user-binfmt  qemu-user-static ncurses-devel expat-devel elfutils-libelf-devel pciutils-devel openssl-devel binutils-devel qemu-system-riscv-core
$ sudo dnf groupinstall "Development Tools" "C Development Tools and Libraries"
  • on Ubuntu
$ sudo apt-get install autoconf automake autotools-dev curl python3 libmpc-dev libmpfr-dev libgmp-dev gawk build-essential bison flex texinfo gperf libtool patchutils bc zlib1g-dev libexpat-dev libncurses-dev openssl libiberty-dev libssl-dev dkms libelf-dev libudev-dev libpci-dev golang-go qemu-user-static

To build uroot, you need to install go 1.17, refer to https://tecadmin.net/how-to-install-go-on-ubuntu-20-04/. You can use the following reference to check the go version.

$ go version

go version go1.17 linux/amd64

2. Build all from source​

  • Download source code
$ git clone https://github.com/sophgo/bootloader-riscv.git
$ git clone https://github.com/sophgo/zsbl.git
$ git clone https://github.com/sophgo/opensbi.git
$ git clone https://github.com/sophgo/linux-riscv.git

# clone u-boot
$ git clone https://github.com/sophgo/u-boot.git
# clone grub
$ git clone git://git.savannah.gnu.org/grub.git
$ pushd grub
$ git remote add github.com_tekkamanninja https://github.com/tekkamanninja/grub.git
$ git fetch github.com_tekkamanninja
$ git checkout github.com_tekkamanninja/riscv_devel_Nikita_V3
$ popd

  • Build Cross toolchain for bsp

    Enter the bsp directory which is the same level as bootloader-riscv, zsbl, opensbi, u-boot, grub2 and linux-riscv, and build Cross toolchain by the following command:

$ CHIP=mango
$ source bootloader-riscv/scripts/envsetup.sh
$ build_rv_gcc

# get the following folders:
.
├── bootloader-riscv
├── zsbl
├── opensbi
├── linux-riscv
├── u-boot
├── grub
└── gcc-riscv
      ├── gcc-riscv64-unknown-elf
      └── gcc-riscv64-unknown-linux-gnu
  • Build all
# build single CHIP:
$ CHIP_NUM=single
$ source bootloader-riscv/scripts/envsetup.sh
$ build_rv_all

# build multi chip:
$ CHIP_NUM=multi
$ source bootloader-riscv/scripts/envsetup.sh
$ build_rv_all
  • If you have chosen a single chip, the output files will be located in the install/soc_mango/single_chip directory.
  • If you have chosen multiple chips, the output files will be located in the install/soc_mango/multi_chip directory.

3. Build perf tool on Ubuntu​

  • Use the following commands to extract the perf source package from linux-riscv and get the build script.
$ CHIP=mango
$ source bootloader-riscv/scripts/envsetup.sh
$ build_rv_ubuntu_perf_tool
  • Find the previously mentioned files in install/soc_mango/riscv64/tools/perf directory.
.
└── tools
       └── perf
             ├── build-perf.sh
             ├── perf-6.1.22
             └── perf-6.1.22.tar
  • Copy the tools directory to the SG2042 EVB, and execute the build-perf.sh to make and install perf tool. If you use the latest ubuntu-sophgo.img, the tools exists in the /home/ubuntu directory.
$ cd tools/perf/
$ source build-scripts.sh
  • Use the perf tool.
$ perf list
$ perf stat
$ perf bench
