Update

2025/03/11

prebuilt image you can download these images directly.

Tag 0.0.4.1 included nvme with one only rootfs parition and sd-uboot.image. But the sd-uboot image does not work(debugging), so please use the sd-uboot.img

Tag 0.0.5-beta include nvme rootfs with multi paritions and sd-uboot does not work also, please refer to above notice.

2024/12/10

Now you can use mkimg-unmatched-debian.sh to generate one rootfs for nvme, more defail please see README

2024/08/28

Now some changes from Debian lead to the image for Unmatched pre-built does not work.

You can download the refreshed image for nvme from my personally site. The user&passwd is rv:rv.

Depends

sudo apt install -y qemu-user-static qemu-system qemu-utils qemu-system-misc binfmt-support

How to build image

Need docker docker-compose installed, then type:

sudo DOCKER_BUILDKIT=1 docker-compose build nvme
sudo docker-compose up nvme

Or:

sudo make unmatched

Two image files will be generated into image:

nvme-rootfs.img.xz  sd-uboot.img

How to install image

The nvme-rootfs.img you can use cmd below to flash to nvme:

sudo dd if=nvme-rootfs.img of=/dev/[nvme-device] bs=64k iflag=fullblock oflag=direct conv=fsync status=progress

If the bootloader you want to use it that in sd card, you can dd the sd-uboot.img to sd card:

sudo dd if=sd-uboot.img of=/dev/[sd-device] bs=64k iflag=fullblock oflag=direct conv=fsync status=progress

Username and passwd

user: root, passwd: sifive
user: rv,   passwd: rv

Once you boot the system, maybe the first thing is sudo apt update && upgrade.

Install Desktop

First you need to have a graphics card, such as amd radeon(soft lockup issue when boot) like me, then run:

sudo apt install firmware-amd-graphics

You need add non-free-firmware component in sources.list file.

Increase nvme disk

Maye you need reszie nvme volume with cmd below:

parted -f -s /dev/nvme0n1 print
echo 'yes' | parted ---pretend-input-tty /dev/nvme0n1 resizepart 1 100% 
resize2fs /dev/nvme0n1p1

(Better to reboot after this operation)

sync time

If you see the info after apt update:

E: Release file for https://mirror.iscas.ac.cn/debian-ports/dists/sid/InRelease is not valid yet (invalid for another 48d 6h 38min 42s).

Please fix it by ntpdate:

sudo ntpdate cn.pool.ntp.org
