rpi qemu

先克隆工具链

git clone https://gitee.com/mirrors/riscv-gnu-toolchain
cd riscv-gnu-toolchain
mkdir /opt/riscv
./configure --prefix=/opt/riscv

for newlib

make

for linux

make linux

for linux 32

./configure --prefix=/opt/riscv --with-arch=rv32gc --with-abi=ilp32d
make linux

或者直接安装 riscv 工具链

sudo apt install gcc-riscv64-linux-gnu gcc-riscv64-unknown-elf

sudo apt install gcc-arm-linux-gnueabi gcc-arm-linux-gnueabihf

sudo apt install gcc-arm-none-eabi

sudo apt install gcc-aarch64-linux-gnu

克隆u-boot和opensbi

git clone https://gitlab.com/u-boot/u-boot.git
git clone https://gitee.com/mirrors/OpenSBI

build u-boot

for arm

export CROSS_COMPILE=arm-linux-gnueabi-
make qemu_arm_defconfig
make
qemu-system-arm -machine virt -nographic -bios u-boot.bin

for aarch64

sudo apt-get install gcc-aarch64-linux-gnu
export CROSS_COMPILE=aarch64-linux-gnu-
make qemu_arm64_defconfig
make
qemu-system-aarch64 -machine virt -nographic -cpu cortex-a57 -bios u-boot.bin

riscv64

cd u-boot
export CROSS_COMPILE=riscv64-linux-gnu- 
make qemu-riscv64_smode_defconfig
make

arm64

cd u-boot
export CROSS_COMPILE=riscv64-linux-gnu- 
make qemu_arm64_defconfig
make

qemu-system-arm -machine virt -nographic -bios u-boot.bin -cdrom alpine-standard-3.18.4-armv7.iso -boot d

qemu-system-arm -machine virt -nographic -bios u-boot.bin -hda root.img -cdrom alpine-standard-3.18.4-armv7.iso -boot d
