官網給出的編譯方法:

make PLAT=fvp BL33=/bl33.bin fip

針對qemu_v8平臺的編譯，真實情況是這樣的：

CROSS_COMPILE="/usr/bin/ccache /home/test/workspace/code/optee_3.14/build/…/toolchains/aarch64/bin/aarch64-linux-gnu-" make -C /home/test/workspace/code/optee_3.14/build/…/trusted-firmware-a BL32=/home/test/workspace/code/optee_3.14/build/…/optee_os/out/arm/core/tee-header_v2.bin BL32_EXTRA1=/home/test/workspace/code/optee_3.14/build/…/optee_os/out/arm/core/tee-pager_v2.bin BL32_EXTRA2=/home/test/workspace/code/optee_3.14/build/…/optee_os/out/arm/core/tee-pageable_v2.bin BL33=/home/test/workspace/code/optee_3.14/build/…/edk2/Build/ArmVirtQemuKernel-AARCH64/RELEASE_GCC5/FV/QEMU_EFI.fd PLAT=qemu QEMU_USE_GIC_DRIVER=QEMU_GICV2 ARM_TSP_RAM_LOCATION=tdram BL32_RAM_LOCATION=tdram SPD=opteed DEBUG=0 LOG_LEVEL=30 all fip

翻譯一下就是:

make -C trusted-firmware-a BL32=tee-header_v2.bin BL32_EXTRA1=tee-pager_v2.bin BL32_EXTRA2=tee-pageable_v2.bin BL33= QEMU_EFI.fd PLAT=qemu QEMU_USE_GIC_DRIVER=QEMU_GICV2 ARM_TSP_RAM_LOCATION=tdram BL32_RAM_LOCATION=tdram SPD=opteed DEBUG=0 LOG_LEVEL=30 all fip
