Loongson 2K0300 (EOL)

Hardware Notes

Loongson 2K0300 (JiuJiu Pi) uses the Loongson 2K0300 processor with the LoongArch architecture at 1 GHz. It supports low power usage, touch input, Liji DDR4, a gigabit Ethernet port, and multiple interfaces, and is powered via standard Type-C.

Hardware: Loongson JiuJiu Pi, USB HDMI capture card, CH9329 + CH340 combo cable

Integrated Image Deployment

The One-KVM image for Loongson JiuJiu Pi is built on Loongnix (old world).

Image notes

Reminder

Virtual storage (MSD) and virtual USB devices are only available in OTG mode. These virtual USB features are not supported when using CH9329 HID.

  • The system is based on Loongnix with One-KVM preinstalled. The image is provided as a rootfs tarball. After boot, access https://IP:443.

  • Due to memory limits, a 1 GB swap file (/swap.img) is included. The base system is about 4.8 GB. For TF card models, use an 8 GB (or larger) high-speed TF card.

  • OTG requires hardware modifications per official docs, so this guide uses the CH9329 + CH340 combo cable. The kernel includes OTG modules and USB gadget works; advanced users can test OTG if needed.

  • For TF card models, no file changes are needed. For Wi-Fi card models, the archive includes vmlinuz-tf and vmlinuz-wifi under /boot/. Rename the one you need to vmlinuz and edit boot.cfg accordingly.

mkdir /mnt/sdc1
sudo mount /dev/sdc1 /mnt/sdc1
# Use --strip-components=2 to remove the top two folders
sudo tar -zvxf One-KVM_by-SilentWind_2k0300_241025.tar.gz --strip-components=2 -C /mnt/sdc1 && sync
sudo nano boot.cfg
sudo cd /mnt/sdc1/boot
# Rename to vmlinuz as needed and edit boot.cfg
cp vmlinuz-tf vmlinuz
sudo nano boot.cfg
sudo umount /dev/sdc1
