SDK Build Process Overview#
This section takes the execution process of the make CONF=k230d_canmv_defconfig command as an example.
Download the buildroot-2025.02.1.gz archive from the buildroot official website, and extract it to output/buildroot-2025.02.1/
Use the buildroot-overlay directory to overwrite the output/buildroot-2025.02.1/ directory
rsync -a buildroot-overlay/ output/buildroot-2025.02.1/
Enter the output/buildroot-2025.02.1/ directory, use k230d_canmv_defconfig to configure buildroot, and specify the output directory as output/k230d_canmv_defconfig
make -C output/buildroot-2025.02.1 k230d_canmv_defconfig O=/home/wangjianxin/k230_linux_sdk/output/k230d_canmv_defconfig
Enter the output/k230d_canmv_defconfig directory and compile
make -C /home/wangjianxin/k230_linux_sdk/output/k230d_canmv_defconfig all
