AMP Quick Start: Build

5. Quick start

5.3 Build

Build and package the complete SDK:

./build.sh

Rebuild only the AMP firmware:

./build.sh amp

Build U-Boot and the Linux Kernel separately:

./build.sh uboot
./build.sh kernel

Clean and rebuild everything:

./build.sh cleanall
./build.sh

./build.sh amp parses the compile nodes in the ITS file, builds the corresponding RT-Thread/HAL projects, and generates amp.img. Locate the output with:

find . -name amp.img -printf '%TY-%Tm-%Td %TH:%TM  %p\n' | sort

5.4 Build individual components

The following RK3562 example builds the Linux Kernel separately:

cd <SDK>/kernel
export ARCH=arm64
export CROSS_COMPILE=<SDK>/prebuilts/gcc/linux-x86/aarch64/<toolchain>/bin/aarch64-none-linux-gnu-
make rockchip_linux_defconfig
make <board>-linux-amp.img -j$(nproc)

AP RT-Thread:

cd <SDK>/rtos/bsp/rockchip/<ap-target>/
./build.sh <cpu_id|all>
./mkimage.sh

AP bare metal:

cd <SDK>/hal/project/<ap-target>/GCC
./build.sh <cpu_id|all>
cd ..
./mkimage.sh

U-Boot:

cd <SDK>/u-boot
make <soc>_defconfig rk-amp.config
./make.sh

Replace <board>, <ap-target>, <soc>, and the toolchain path with the names used by the current Firefly SDK.
