OneCloud Pro

Hardware Introduction

The OneCloud Pro features an S912 octa-core CPU, paired with 2GB RAM and 8GB internal storage. It is equipped with one Gigabit Ethernet interface, two USB 2.0 ports, and provides a TF card slot and HDMI output.

Integrated Package Deployment

  1. Prepare SD Card Boot Media: Write the One-KVM integrated package to an SD card and insert it into the OneCloud Pro SD card slot.
  2. Boot from SD Card: For the first time flashing from the original system, hold the reset button while plugging in power. Release the reset button after the OneCloud logo disappears. For subsequent flashing, the system will automatically boot from the SD card upon power-on.
  3. Install System to EMMC: After the SD card system successfully boots, log into the terminal through the One-KVM web terminal or SSH, and use the armbian-install command to select the corresponding model (v1.1 board corresponds to code 201, v1.2 board corresponds to code 213) to install the One-KVM system.

Usage Instructions

Hardware safety warning

To avoid issues such as the target failing to boot or detect devices (and in rare cases hardware damage), take one of these precautions before using a dual-headed USB cable:

Option 1: cut/remove the red 5V (VCC) wire in the USB cable so only the data lines (D+/D−) and ground remain, breaking the power path.

Option 2: insert a USB hub with its own power switch into the USB link and keep that switch off while connecting.

Some low-power targets can back-power from the KVM via the OTG port before their main power is applied, leaving them in a bad state that persists even after you power them normally.

Unless you fully understand the risks, use one of the safeguards above to protect your hardware.

Data safety reminder

Avoid hard power-offs. Cutting power while eMMC writes are in progress can corrupt data.

If you must cut power, run sync after write operations. For shutdowns/reboots, prefer poweroff or reboot so the system flushes data cleanly.

SSH Remote Login

The Armbian system enables SSH by default, with initial SSH username/password as root/1234.

System upgrade warning

It is not recommended to use apt upgrade to upgrade the kernel and device tree, as this may cause system abnormalities and render the OTG function unusable.

Hardware Connection

The USB port next to the QR code is the OTG port for connecting USB dual-male cable. The USB port next to the network port is a regular USB port for connecting USB HDMI capture card.

ATX Power Control

The motherboard has directly usable GPIO pins that can be used for ATX power switch control.

If you want to use ATX control for physical power on/off functionality, please connect the power-on cable properly.
