Installation Steps

Preparing Source and Environment

Get the toolchain:

wget https://static.dev.sifive.com/dev-tools/freedom-tools/v2020.12/riscv64-unknown-elf-toolchain-10.2.0-2020.12.8-x86_64-linux-ubuntu14.tar.gz
tar -xvzf riscv64-unknown-elf-toolchain-10.2.0-2020.12.8-x86_64-linux-ubuntu14.tar.gz
export PATH=path/to/toolchain/bin:$PATH

Clone the repository and configure:

mkdir nuttx && cd nuttx
git clone https://github.com/apache/nuttx.git nuttx
git clone https://github.com/apache/nuttx-apps.git apps

Building NuttX

Compile nuttx.bin:

cd nuttx
make distclean
./tools/configure.sh star64:nsh
make -j$(nproc)
riscv64-unknown-elf-objcopy -O binary nuttx nuttx.bin

Build the file system:

make export
pushd ../apps
tools/mkimport.sh -z -x ../nuttx/nuttx-export-*.tar.gz
make import
popd
genromfs -f initrd -d ../apps/bin -V "NuttXBootVol"

Write the dtb file:

  • Download the dtb:
wget https://github.com/starfive-tech/VisionFive2/releases/download/JH7110_VF2_515_v5.11.3/jh7110-visionfive-v2.dtb
  • In the nuttx directory:
cat << EOF > nuttx.its
/dts-v1/;

/ {
  description = "NuttX FIT image";
  #address-cells = <2>;

  images {
    vmlinux {
      description = "vmlinux";
      data = /incbin/("./nuttx.bin");
      type = "kernel";
      arch = "riscv";
      os = "linux";
      load = <0x0 0x40200000>;
      entry = <0x0 0x40200000>;
      compression = "none";
    };

    ramdisk {
      description = "buildroot initramfs";
      data = /incbin/("./initrd");
      type = "ramdisk";
      arch = "riscv";
      os = "linux";
      load = <0x0 0x46100000>;
      compression = "none";
      hash-1 {
        algo = "sha256";
      };
    };

    fdt {
      data = /incbin/("./jh7110-visionfive-v2.dtb");
      type = "flat_dt";
      arch = "riscv";
      load = <0x0 0x46000000>;
      compression = "none";
      hash-1 {
        algo = "sha256";
      };
    };
  };

  configurations {
    default = "nuttx";

    nuttx {
      description = "NuttX";
      kernel = "vmlinux";
      fdt = "fdt";
      loadables = "ramdisk";
    };
  };
};

Ensure you have u-boot-tools installed on your system:

# sudo apt install u-boot-tools
# sudo pacman -S uboot-tools
# sudo dnf install u-boot-tools

Create the fit:

mkimage -f nuttx.its -A riscv -O linux -T flat_dt starfiveu.fit

Building the Image

Download the SD card image and flash:

wget https://github.com/starfive-tech/VisionFive2/releases/download/JH7110_VF2_515_v5.11.3/sdcard.img
sudo dd if=sdcard.img of=/dev/your/device bs=1M status=progress

Flashing the Image

Flash the SBI environment onto the SD card:

unxz -k canmv230-sdcard.img.xz
sudo dd if=canmv230-sdcard.img of=/dev/your/sdcard bs=1M status=progress

Replace the fit file:

mkdir mnt
sudo mount /dev/your/sdcard/p3 mnt
sudo cp starfiveu.fit mnt/
sudo umount mnt
rm -r mnt

Logging into the System

Connect to the development board via serial port.

Expected Results

The development board outputting boot information normally.
