OpenIPC SBC Ground Stations

OpenIPC SBC Ground Stations is the unified image builder for OpenIPC FPV receiver devices based on single-board computers. The upstream repository describes it as a Buildroot 2 based image builder for supported ground-station hardware.

The project is software tooling rather than a single hardware board: it builds images, boot scripts, bootloader files, root filesystems, and update packages for several receiver platforms.

Supported Hardware

The upstream README lists support for:

  • RunCam Wifilink.
  • Emax Wyvern-Link.
  • Radxa Zero 3 when used with one of the supported receiver options.
  • OpenIPC Bonnet.

The latest release page also links to older or separate image tracks for Radxa Zero 3, Radxa Rock 2F, and Orange Pi 3B/5/5 Plus.

Editions and Releases

The latest release page is an index for available SBC Ground Station editions. It currently marks the Buildroot Edition as the community-recommended default for most users.

  • Buildroot snapshot provides current Buildroot images and update packages for platforms such as radxa_zero3, openipc_bonnet, runcam_wifilink, and emax_wyvern-link.
  • Stock Edition releases remain available for existing Radxa Zero 3 users, including v1.9.9, 2.0.0 beta 2, and APFPV v0.0.1.
  • Separate release pages are listed for Orange Pi and Radxa Rock 2F.

Flashing and Updates

For eMMC devices, the project documents an SD-card assisted flashing method. Copy <platform>_sdcard.img and <platform>_boot.scr from the same release to a FAT32 card, rename the boot script to boot.scr, and boot the device from that card. U-Boot writes the image to eMMC and then reboots into the flashed system.

Boards without eMMC can use a normal SD-card image flashed with a tool such as balenaEtcher.

Advanced methods include dd from a booted system, bootloader-only flashing, and maskrom flashing with RKDevTool or rkdeveloptool.

Once flashed, Buildroot images can be updated by copying the matching <platform>.tar.gz package to a FAT SD card, the DVR partition, or eMMC storage and rebooting. The README also documents sysupgrade -u -r, local build.sh ssh-flash, and local build.sh flash workflows.

Runtime Features

The README documents factory reset through the right button during boot or the firstboot command.

It also describes gadget mode, triggered with the left button during boot. Through the OTG port, gadget mode exposes DVR access, serial access, and a network interface at 192.168.5.1.

Custom Builds

Custom builds require a Linux or WSL2 environment with Buildroot dependencies installed:

Terminal window
git clone https://github.com/OpenIPC/sbc-groundstations.git
cd sbc-groundstations
./build.sh

Use the upstream Buildroot documentation when customizing images or adding packages.
