K230 Linux SDK

This document uses the k230d_canmv_defconfig configuration as an example. If you use other configurations, replace k230d_canmv_defconfig with correct names. All the configurations supported by this sdk, can be found in buildroot-overlay/configs directory.

Install toolchain and dependencies

download Xuantie-900-gcc-linux-6.6.0-glibc-x86_64-V3.0.2-20250410.tar.gz toolchan from https://www.xrvm.cn/community/download?id=4433353576298909696 uncompress the toolchain to the /opt/toolchain(Refer command):

mkdir -p /opt/toolchain;
tar -zxvf Xuantie-900-gcc-linux-6.6.0-glibc-x86_64-V3.0.2-20250410.tar.gz -C /opt/toolchain;

install dependencies(Refer command):

apt-get install -y   git sed make binutils build-essential diffutils gcc  g++ bash patch gzip \
        bzip2 perl  tar cpio unzip rsync file  bc findutils wget  libncurses-dev python3  \
        libssl-dev gawk cmake bison flex  bash-completion parted curl  xz-utils

k230d_canmv_ilp32_defconfig required ubuntu 22.04 or 24.04 and install rv64ilp32 toolchain(refer command):

wget -c https://github.com/ruyisdk/riscv-gnu-toolchain-rv64ilp32/releases/download/2024.06.25/riscv64ilp32-elf-ubuntu-22.04-gcc-nightly-2024.06.25-nightly.tar.gz;

mkdir -p /opt/toolchain/riscv64ilp32-elf-ubuntu-22.04-gcc-nightly-2024.06.25/;tar -xvf riscv64ilp32-elf-ubuntu-22.04-gcc-nightly-2024.06.25-nightly.tar.gz -C /opt/toolchain/riscv64ilp32-elf-ubuntu-22.04-gcc-nightly-2024.06.25/;

build

make CONF=k230d_canmv_defconfig #build k230d canmv image (kernel and rootfs both 64bit);
# make CONF=k230d_canmv_defconfig  BR2_PRIMARY_SITE=https://kendryte-download.canaan-creative.com/k230/downloads/dl/ #download package from kendryte
# make CONF=k230_canmv_defconfig # build k230 canmv image
# make CONF=k230d_canmv_ilp32_defconfig  #build k230d canmv 32bit rootfs;
# make help # view help

BR2_PRIMARY_SIT configuration primary download site for example: make CONF=k230d_canmv_defconfig BR2_PRIMARY_SITE=https://kendryte-download.canaan-creative.com/k230/downloads/dl/

  • demo source code directory :buildroot-overlay/package/ai_demo

    ls buildroot-overlay/package/ai_demo; #can see all ai demo
    ls buildroot-overlay/package/ai_demo/face_detection/;#face_detection code
  • The compilation method for a single demo (taking face_detection as an example):

    make face_detection-dirclean;make face_detection;#rebuild face_detection demo
  • By default, only the (face_detection) demo is enabled. If other demos are needed, please enable the corresponding demo through the menu:

    make menuconfig;#Target packages  --->canaan package  ---> AI  --->
    [*] face detection
    [ ] demo mix
    [ ] bytetrack
     .............
    [ ] face_mesh
    [ ] face_parse
    [ ] face_pose
    [ ] face_verification
  • If you need to experience the demo, please enter the corresponding directory under /root/app and run the relevant demo

    [root@canaan ~ ]#cd /root/app/face_detection/
    [root@canaan ~/app/face_detection ]ls
    face_detect_image.sh       face_detection_320.kmodel
    face_detect_isp.sh         face_detection_640.kmodel
