先在源码根目录下编译 riscv64 的文件系统。
然后进入子目录 zCore 编译内核,会生成系统镜像zcore.bin
make riscv-image
cd zCore
make build LINUX=1 ARCH=riscv64 PLATFORM=d1 MODE=release
以全志 D1 c906 开发板为例。
下载并编译烧写工具 xfel
:
git clone https://github.com/xboot/xfel.git
cd xfel
make
安装好工具 xfel
,开发板进入 FEL 模式,可在开发板的 Linux 系统中执行 reboot efex
命令进入 FEL 模式。然后运行:
make run LINUX=1 ARCH=riscv64 PLATFORM=d1 MODE=release
-
下载 D1 开发板的 OpenSBI 源码,并编译出镜像 build/platform/thead/c910/firmware/fw_payload.elf:
git clone https://github.com/elliott10/opensbi -b thead cd opensbi make PLATFORM=thead/c910 CROSS_COMPILE=/path/to/toolchain/bin/riscv64-unknown-linux-gnu- SUNXI_CHIP=sun20iw1p1 PLATFORM_RISCV_ISA=rv64gcxthead
或使用预编译的镜像 prebuilt/firmware/riscv/d1_fw_payload.elf.
-
生成包含了 OpenSBI, dtb, zCore 的待烧写固件:
rust-objcopy --binary-architecture=riscv64 ../prebuilt/firmware/d1/fw_payload.elf --strip-all -O binary ./zcore_d1.bin dd if=../target/riscv64/release/zcore.bin of=zcore_d1.bin bs=512 seek=2048
-
启动全志 D1 c906 开发板,并进入 FEL 模式。然后通过烧写工具
xfel
把 zCore 系统镜像载入到 DDR 中:sudo xfel ddr d1 sudo xfel write 0x40000000 zcore_d1.bin sudo xfel exec 0x40000000
zCore 成功引导后, OpenSBI 会将 dtb 加载到高地址 0x5ff00000
,运行如下所示:
OpenSBI smartx-d1-tina-v1.0.1-release
