This repository builds debian sid images for Sophgo cv181x/sg200x based boards such as MilkV Duo256/DuoS (SD Version only) and Sipeed LicheeRvNano.
(Note, we don't support the MilkV Duo, as it does not have enough ram to run Debian)
The images aim to be as close to possible to debian best practices as possible
Logins: root/rv and debain/rv
(root login is disabled via SSH, login via debian, and SU to root if needed)
by default, a rndis interface is started on the USB port, and the IP address is 10.42.0.1 - It also starts a DHCP Server on that interface, so your PC should automatically get an IP address in the 10.42.0.x range
To Disable the rndis interface, you can run the following command:
systemctl disable usb-gadget-rndis
There is also a option to start a serial port (ACM) interface instead of the rndis interface, to do this, you can run the following command:
systemctl disable usb-gadget-rndis
systemctl enable usb-gadget-acm
After executing these commands, you need to reboot.
For the LicheeRVNano board, Wifi is enabled. To connect to your wifi network, execute the following command and select "Activate a connection" and select your wifi network:
nmtui
for Boards with eithernet, they should automatically get a IP address if your network has a DHCP Server.
The images are based on the vendor 5.10 kernel, but exclude the following drivers:
- mipi-rx/csi drivers
- mipi-tx/dsi drivers
- TPU Drivers
- Any of the Video Encoding Drivers
(this is mainly due to compatibility reasons with the glibc version in debian and musl version used in the vendor images)
The images, by default, do not allocate any memory for the ION heap, as they are unused in this image, so you get the full memory of each device
The images also include the remoteproc and mailbox drivers so you can load up ardunio/freertos images on the small C906 core.
This image also adds the debian repository for https://github.com/Fishwaldo/sophgo-sg200x-packages so you can install additional repositories. The debian repository is hosted at https://sophgo.my-ho.st:8443/ which pulls down the compiled debian packages from the above github repository occasionally.
To build a stock image with no modifications:
podman run --privileged -it --rm -v ./configs/:/configs -v ./image:/output ghcr.io/fishwaldo/sophgo-sg200x-debian:master make BOARD=licheervnano image
Replace the licheervnano with the board you want to build for:
- duo256
- licheervnano
The Docker image will build the image and place it in the image directory
To flash from linux, either build your own image, or download a image from the releases page, and then run the following command:
sudo dd if=image/licheervnano_sd.img of=/dev/sdX bs=4M status=progress
From windows, you can use tools such as balena etcher
where the licheervnano_sd.img is the image file you want to flash, and /dev/sdX is the device you want to flash to. (if you build for a different board, the image file name will be different)
addition make targets are available when building:
- image - builds the image
- clean - cleans the build directory
- linux - build a kernel debian package
- fsbl - build the fsbl debain package (that includes cvitek-fsbl, opensbi and u-boot)
The configs directory contains patches, configuration and device tree files that are used to build the image.
The configs/common directory contains the common configuration for all boards, and the configs/licheervnano and configs/duo256 directories contain the board specific configuration.
To add packages to the image, either add the package name in PACKAGES variable of configs/settings.mk or if the packae is specific to a board, add it to the configs/<board>/settings.mk file
Patches for the kernel, opensbi, u-boot or fsbl can be placed in configs/common/patches/ or configs/<board>/patches/ depending what they are for.
To assist with developing the image, you can get a shell in the docker container by running:
docker run --privileged -it --rm -v ./configs/:/configs -v ./image:/output -v ./scripts/:/builder builder /bin/bash
inside the container, packages are build in the /builder/ directory, and the rootfs is placed at /rootfs/ directory
- Add support for the DuoS EMMC Board
- DeviceTree Overlay Support
- Add support for the MIPI-CSI/DSI drivers (Sample applications would be in the sophgo-sg200x-packages repository if they do not depend upon a musl libc version)
- Add support for the TPU drivers
- Possibly mainline kernel support via the sophgo linux for-next repositories
