I made this to work on sbc:s both with or without a boot partition: https://github.com/UnconnectedBedna/shrink-backup Uses rsync so it's way faster than a dd. Creates an img file at minimum size. Autoexpansion on restore available for Armbian. Also contains a systemd-nspawn utility if you want to make changes to the img file itself.

Title: [Working Image + Patch] Orange Pi 4A (T527) - Fast Ethernet Fixed on Mainline 7.0 Edge Hi everyone, Since the Orange Pi 4A (Allwinner T527) is currently an unmaintained community target on the bleeding-edge Mainline 7.0 Edge branch, the default images boot up completely blind with cannot attach to PHY (error: -ENODEV) errors. After a lot of debugging, I (with assistance from Gemini - who wrote this post) managed to successfully compile a full, functional Debian Trixie image where Ethernet works perfectly (capped at 100M) and the green status LED pulses a native heartbeat. The secret sauce is that the board uses a Motorcomm YT8531 transceiver, but the kernel falls back to a Generic PHY driver which fails to calibrate the high-frequency RGMII clock skews required for Gigabit speeds. Dropping the link frequency down to 100 Mbps Full Duplex bypasses the timing sensitivity completely, allowing NetworkManager to instantly pull a stable IPv4 DHCP lease! (Note: Mainline 7.0 does not yet have internal C drivers for the T527 audio codec or the SDIO mmc1 bus clocks, so internal audio and onboard Wi-Fi remain offline. Use a USB sound/Wi-Fi dongle if needed). I can't vouch whether HDMI is working or not as I was debugging it using a serial cable. 📦 Download the Image https://drive.google.com/drive/folders/1ieu3TBn2nSP0BaJvJMIhLeLM6kt-x8bX?usp=sharing 🛠️ The Device Tree Patch File I managed to diff the radxa-cubie-5e.dts file and patch it to get it to kind of work with the opi 4a. The patchfile is also in the google drive folder and supplied as an attach here. To include this in your own Armbian build environment, delete any old patches and save this file exactly as: build/userpatches/kernel/archive/sunxi-7.0/zzzz-working-opi4a.patch It wipes out the broken default configurations and replaces them with clean, compiling mainline mappings. You can then build the image using this: ./compile.sh build BOARD=orangepi-4a BRANCH=edge BUILD_DESKTOP=no BUILD_MINIMAL=no KERNEL_CONFIGURE=no RELEASE=trixie USERPATCHES_ALLOWED=yes SYSTEM_VERBOSE=yes FORCE_REBUILD=yes 📝 Step-by-Step Instructions to Lock Down the 100M Connection Because the Generic PHY driver cannot process 1Gbps packets correctly, the interface will sit in an unconfigured DOWN loop upon initial boot. Run these steps via your serial terminal loop to bring it online and automate it: Force the hardware down to 100M to clear the packet queue: sudo ethtool -s end0 speed 100 duplex full autoneg off Tell NetworkManager to explicitly negotiate the port: sudo nmcli device connect end0 Make the 100M setting permanent so it survives a reboot: sudo nmcli connection add type ethernet con-name eth-100m ifname end0 802-3-ethernet.auto-negotiate no 802-3-ethernet.speed 100 802-3-ethernet.duplex full ipv4.method auto ipv6.method disabled Automate the green status heartbeat LED: Open /etc/rc.local and add this line right above exit 0 echo heartbeat > /sys/class/leds/green:status/trigger Reboot, and you should have a 100% automated, maintenance-free, fully operational network target - with some tweaking will hopefully get you to the next stage as apt will be working. Hope this helps anyone else struggling to get this community board running on modern releases! zzzz-radxa-to-orangepi4a-fix.patch
