Orange Pi 4A (Allwinner T527 / A523, sun55i-a523) — new mainline image coming in a few days Hi all, A quick heads-up for anyone following the Orange Pi 4A / Allwinner T527 (A523) mainline effort: a new image, v0.3, is coming in the next few days. It's based on mainline Linux 6.18 (longterm) and it's a decent step up from v0.2, so I wanted to give some advance notice. What's new in v0.3: Hardware video decode (VPU): H.264/H.265 decoded on the Cedar VPU — smooth video in the bundled web browser (WebKitGTK), using Allwinner's own cedar + libcedarc stack. GNOME on Wayland (replaces Plasma), accelerated by Panfrost (Mali-G57). The X11 session is intentionally not used — Wayland is much faster on this GPU for both desktop and video. Low-RAM fix: compressed in-RAM swap (zram) is on by default, so the 2 GB board stays responsive under a browser + video instead of freezing. Robustness: the VPU driver now survives a client crashing mid-decode without wedging the board, plus a round of code-audit fixes across the clock, PCIe, DRM, VPU and audio-codec drivers. Everything from before still works: display/KMS, GPU, HDMI + analog audio (headphones with jack detection), Ethernet, WiFi, USB, PCIe/NVMe (not yet tested with a real drive), thermal and cpufreq/DVFS. How it's built: on top of mainline Linux and public community work (linux-sunxi, Armbian and others — credited in the tree), with Allwinner's public documentation and vendor BSP as the hardware reference, plus the project's own patches, each one validated on real hardware. Some of this has been posted to the linux-sunxi / upstream lists and picked up by maintainers. This is a spare-time hobby project, shared as-is (async, no live support). Sources, patches and images are on GitHub — I'll post here again when the release is up: GitHub: https://github.com/ut-slayer/orangepi-4a-mainline Testers and feedback are very welcome. Thanks!

I created a fully automated TTN UDP Gateway installer for the Bobcat 300 (G285/G29X). Prerequisite: First install Armbian by following the instructions in the Bobcat-Armbian project: https://github.com/sicXnull/Bobcat-Armbian After Armbian has been installed, use the installer from my repository: https://github.com/AdvdLaar/Bobcat300-TTN Note: This installer is intended for TTN UDP Gateway operation only. It does not install or configure Helium. Features: Automatic detection of G285 and G29X hardware. Selectable TTN region (EU868, US915, AS923, AU915, IN865, RU864, CN470, JP923, KR920). Automatic Gateway EUI generation from the MAC address. No git clone required (downloads the repository as a ZIP using wget). Cleans up previous installations before installing. Verifies the SPI device and required files before continuing. Configures the packet forwarder automatically. Includes a showgatewayinfo.sh utility to display the configured Gateway EUI and TTN server. The installer has been tested on my Bobcat 300 G285 and performs a clean installation on an Armbian system without requiring any manual configuration. Many thanks to sicXnull for making the Armbian port possible. Without that project, this installer would not have been possible. Hopefully this is useful for others who want to convert their Bobcat into a TTN UDP Gateway. Have fun with your TTN gateway. Best regards, Ad

Great job. I have the same OPI5+. The fan has 3 pins. Can you tell me how to desolder the wires?
