Trying ArceOS
ArceOS
ArceOS is an experimental modular operating system written in Rust.
As I am taking the OS course this semester, my job is to continue Ming Yang’s work. He had implemented an async runtime for arceos and tested DWMAC on StarFive VisionFive 2 board.
And I am going to absruct his implemenation, move them into separate crate, possily merge the async runtime for ArceOS too.
StarFive VisionFive 2
StarFive VisionFive 2 is a 4 core, 64 bit, RV64GC SBC, with highest freq to 1.5 GHz.
The board includes LPDDR4 memory (up to 8 Gi) and onboard SD card slot, as well as:
- 2 RJ45 gigabit ethernet ports
- M.2 M-key
ArceOS module axasync
The first step is to build the Docker image, which prepares the environment for flashing the kernel image onto the board.
The initial challenge I encountered was that Cargo crates failed to download, even though policy routing was correctly configured on my software router along with DNS zones and static.crates.io was reachable with a stable ping.
After tracing the connection using curl, I discovered that the issue was once again related to the MTU. Having it set to 1420, the problem solves.
As Ming Yang implemented an async runtime for ArceOS. Under the directory there is an example to start a TCP server and client.
Check out commit 3584af374ed5b9304de69cf264258c06371a1fbf and run it on QEMU:

QEMU: TerminatedBooting ArceOS on VisionFive 2
Boot procedure on RISC-V follows:
BootROM -> SPL -> SBI -> U-Boot -> OS
SPL (Secondary Program Loader) is a minimal bootloader that initializes the DDR memory and basic hardware required to load the next stage.
And U-Boot, a more fully-featured bootloader, is responsible for loading the OS kernel, setting up device drivers, and preparing the environment for the operating system.
Compile U-Boot and OpenSBI
My laptop is debian 13, these pacakges are needed to build U-Boot:
sudo apt install gnutls-dev openssl-dev swig gcc-risc64-linux-gnu
export CROSS_COMPILE=riscv64-linux-gnu-Then just as stated in VisionFive2 U-Boot Documentation, I cloned U-Boot and OpenSBI to build the SPL image.
Flash to SD card
Finally it comes to flashing. Package disk provides sdisk on debian. Just install it. However, it’s always harmless to backup:
dd if=/dev/sda1 of=tf-sda1-bk4096+0 records in
4096+0 records out
2097152 bytes (2.1 MB, 2.0 MiB) copied, 0.119711 s, 17.5 MB/sThen creating the partitions and format the thrid one:
sgdisk --clear \
--set-alignment=2 \
--new=1:4096:8191 --change-name=1:spl --typecode=1:2E54B353-1271-4842-806F-E436D6AF6985 \
--new=2:8192:16383 --change-name=2:uboot --typecode=2:BC13C2FF-59E6-4262-A352-B275FD6F7172 \
--new=3:16384:1654784 --change-name=3:system --typecode=3:EBD0A0A2-B9E5-4433-87C0-68B6B72699C7 \
/dev/sdamkfs.vfat -F32 /dev/sda3Now program the SD card as mentioned above. Under ArceOS there is Makefile to generate kernel image:
apt install u-boot-tools
make A=examples/async_server ARCH=riscv64 PLATFORM=riscv64-starfive \
LOG=debug NET=y SMP=4 BUS=mmio \
FEATURES=net,driver-dwmac,bus-mmio \
APP_FEATURES=default,starfive starfiveCopy all files to partition 3.
ls /mnt/It should contain the following content.
arceos.itb uEnv.txtTodo
Two challenges remain:
After building SPL and U-Boot and flashing, SPL failed to read partition 2, and U-Boot failed to start:
U-Boot SPL 2026.01-rc1-00156-g62b45e82bdbf (Nov 01 2025 - 12:42:20 +0800)

StarFive #Based on VisionFive 2 reference manual VisionFive2_SW_TRM.pdf and VisionFive2_QSG.pdf, I found that StarFive maintains their own forks of U-Boot and OpenSBI. The next task is to investigate into their forks and find the reason why the SPL cannot load U-Boot.
Debugging
Boot mode
After reading Installing Debian On StarFive VisionFiveV2, I found that I should switch the boot method to 1-bit QSPI Nor Flash.
Now U-Boot loads:
U-Boot SPL 2021.10 (Feb 28 2023 - 21:44:53 +0800)
DDR version: dc2e84f0.

StarFive #So I have now verified that my SPL and U-Boot firmware function correctly.
Debian image
I downloaded newest debian image release from starfive debian user guide. And then wrote the extracted image to SD card.
Finally, I booted into linux and could login to shell.

To boot ArceOS, first initailize FAT filesystem at /dev/sda3, where the rootfs lives. And then copy arceos.itb to /.
For u-boot to boot ArceOS automatically, write the following to /uEnv.txt:
