Octopus Planet

Hardware Overview

The Octopus Planet box uses an S912 octa-core CPU with 2 GB RAM and 8 GB internal storage. It has a gigabit Ethernet port, two USB 2.0 ports, a TF card slot, and HDMI output.

Integrated Image Deployment

1. Flash a lightweight Android TV firmware: Use USB_Burning_Tool to flash the Android ATV firmware.
2. Prepare a USB boot drive: Write the One-KVM image to a USB drive and insert it into the USB 2 port next to the QR code.
3. Boot from USB: After Android boots, run adb connect yourip, then use adb reboot update to reboot into the USB system. This step is only required once.
4. Install to eMMC: After booting from USB, log in via SSH and run armbian-install. Select the correct model (e.g., model 202 and partition 1) to install One-KVM.

Booting from USB1

Some users report that the device cannot boot from USB2. In that case, use USB1 with the following steps.

After writing the image to the USB drive, edit uEnv.txt in the root of the BOOT partition. Replace FDT=/dtb/amlogic/meson-gxm-khadas-vim2.dtb with FDT=/dtb/amlogic/meson-gxm-q200.dtb. Then edit rc.local under the ROOTFS partition etc directory and add a # at the beginning of line 2 to comment it out.

After successfully booting from USB1 and logging in, edit /etc/rc.local again and remove the # at the beginning of line 2. Save it, then run armbian-install to write the system to eMMC.

Usage Notes

Hardware safety warning

To avoid potential risks (e.g., the target device failing to boot or recognize devices, and in rare cases hardware damage), we strongly recommend one of the following safety measures before using a USB male-to-male cable:

Option 1: Cut or remove the red 5V power wire (VCC) in the USB cable, leaving only data (D+/D-) and ground (GND) to prevent back-powering.

Option 2: Insert a USB hub with an independent power switch in the link, and keep the hub powered off when connecting.

Some low-power devices may draw power back through the USB OTG port when their main power is off, causing an abnormal state that may prevent boot even after main power is restored.

Unless you fully understand the risks, use one of the above protections to keep devices safe.

Data safety

Avoid hard power-offs. Sudden power loss during eMMC writes can cause data loss.

If you must cut power, run sync after write operations to flush data. For shutdown or reboot, use poweroff or reboot so the system can sync and shut down cleanly.

SSH remote login

SSH is enabled by default on Armbian. The initial credentials are root/1234.

Warning

Do not use apt upgrade to upgrade the kernel and device tree; this may break the system and OTG functionality.

Hardware connections

The USB port next to the Ethernet jack is the OTG port for the USB male-to-male cable. The USB port next to the QR code is a normal USB port for the USB HDMI capture card.
