Milk-V Titan Install OS Image

We recommend using the Ubuntu 24.04 system officially released by UltraRISC for Milk-V Titan. This page describes how to write the Ubuntu 24.04 firmware image to an NVMe SSD.

Ubuntu 24.04

The Ubuntu 24.04 firmware is released at:

https://github.com/milkv-titan/titan-ubuntu/releases/tag/2026-0605

Please download all split archive files from the release assets, such as:

ubuntu-24.04-desktop-riscv64-rvck-titan-20260605.img.7z.001
ubuntu-24.04-desktop-riscv64-rvck-titan-20260605.img.7z.002
ubuntu-24.04-desktop-riscv64-rvck-titan-20260605.img.7z.003
...
ubuntu-24.04-desktop-riscv64-rvck-titan-20260605.img.md5

All split archive files must be placed in the same directory before extraction.

To write the image on a PC, connect the NVMe SSD through an M.2 NVMe USB enclosure or adapter, or install the SSD directly into an available M.2 slot on the PC.

注意

Writing the image will erase all existing data on the selected disk. Back up important data before continuing, and make sure you select the Titan target SSD. If you select the wrong disk, such as the PC system disk or another data disk, its data may be destroyed.

ヒント

After the Titan boots from the written SSD, the default system username and password are both ubuntu. You will be prompted to change the password on the first login.

Linux

Install 7-Zip:

sudo apt update
sudo apt install p7zip-full

Extract the firmware image from the first split archive:

7za x ubuntu-24.04-desktop-riscv64-rvck-titan-20260605.img.7z.001

The extracted firmware image will be:

ubuntu-24.04-desktop-riscv64-rvck-titan-20260605.img

Verify the image checksum:

md5sum -c ubuntu-24.04-desktop-riscv64-rvck-titan-20260605.img.md5

Connect the NVMe SSD to the Linux PC using an M.2 NVMe USB enclosure or adapter, or insert it into an available M.2 slot on the PC. Use lsblk to identify the SSD device name:

lsblk

Check the device name, capacity, and model carefully. Do not write the image to the PC system disk or any other non-target disk.

Unmount any mounted partitions on the target SSD. Replace /dev/sdX1 with the actual partition name shown by lsblk:

sudo umount /dev/sdX1

Write the image to the SSD. Replace /dev/sdX with the actual SSD device, not a partition such as /dev/sdX1. This operation will overwrite the selected disk:

sudo dd if=ubuntu-24.04-desktop-riscv64-rvck-titan-20260605.img of=/dev/sdX bs=4M status=progress conv=fsync
sync

After writing is complete, remove the SSD safely, install it into the Titan M.2 M Key slot, and power on the board.

Windows

Install 7-Zip or another archive tool that supports 7z split archives.

Download all split archive files and place them in the same folder. Right-click the .001 file and extract it:

ubuntu-24.04-desktop-riscv64-rvck-titan-20260605.img.7z.001

After extraction, you will get:

ubuntu-24.04-desktop-riscv64-rvck-titan-20260605.img

Connect the NVMe SSD to the Windows PC using an M.2 NVMe USB enclosure or adapter, or insert it into an available M.2 slot on the PC.

Download and install balenaEtcher. Use it to write the image:

1. Click Flash from file and select ubuntu-24.04-desktop-riscv64-rvck-titan-20260605.img.
2. Click Select target and select the Titan target SSD. Check the disk name and capacity carefully to avoid selecting the PC system disk or another data disk.
3. Click Flash! to start writing the image.

After writing is complete, remove the SSD safely, install it into the Titan M.2 M Key slot, and power on the board.
