@Sergioclr Well that is the u-boot root directory. Where the main Makefile is located. I added my own root_key.pem in the patch. The root_key.pem for Allwinner H616/618/313 devices is not a single, universal file, but rather an RSA private key file used for signing bootloader images (TOC0) in secure boot implementations. In many commercial H616-based TV boxes, Secure Boot is enabled by the manufacturer, but the efuses (which store the root key hash) are not permanently locked, allowing the use of custom keys

Hi, guys! I have a tablet Iconbit Skat LE that have android 4.2.2. I want to make from it a ha dashboard. So I found info that I can install armbian. But I have an issue, it doesn't contains my tablet or even company of it. So maybe someone can help to explain?

Same here, but on Orange Pi Zero (Allwinner)

Yesterday I flashed a new sd card (more space) for my rockpi-4b but after switching to the stable channel `armbian-config --cmd STABLE` the update keeps failing: $ sudo apt update Hit:1 http://deb.debian.org/debian trixie InRelease Hit:2 http://security.debian.org trixie-security InRelease Get:3 http://deb.debian.org/debian trixie-updates InRelease [47.3 kB] Hit:4 http://deb.debian.org/debian trixie-backports InRelease Hit:5 https://github.armbian.com/configng stable InRelease Get:6 http://armbian.lv.auroradev.org/apt trixie InRelease [39.4 kB] Get:7 http://armbian.lv.auroradev.org/apt trixie/trixie-utils arm64 Packages [21.4 kB] Get:8 http://armbian.lv.auroradev.org/apt trixie/trixie-desktop arm64 Packages [68 33 B] Fetched 115 kB in 2s (69.5 kB/s) 1 package can be upgraded.

Switching to rolling, updating there works (26.2.0-trunk.722). But the issue persists when switching back to stable. As there have been recent changes https://github.com/armbian/firmware/pull/117 and https://github.com/armbian/firmware/pull/119 and I couldn't find other error reports on the forum, I guess this is an issue of the image packaging. I also plugged back in the old sd card and that system updated without issues.

Good morning. root_key.pem (after compilation) is located in not in u-boot* (root directory). Is that right? Thanks in advance.

@tim zeng sure, but that's not - directly - related, since the Orange PI5 and the Orange Pi3 are different SOCs/SBCs. The only common trait is the poor SW support offered by the vendor.

I am experiencing an issue where the Intel BE200 Wi-Fi module stops working on the NanoPi R5C after upgrading to the latest Armbian v26.2.1 with newer kernels. The iwlwifi driver fails to initialize the device due to a missing configuration profile.

Hello, I have H96 Max TV box with RK3528 chip (4GB RAM, 64GB eMMC, Android 13, build RZX.V01.20240924). Board: RK3528_DDR3_8X4_V12. Problem: Box does not boot from TF card at all. No HDMI output, no DHCP lease, nothing. What I have: TF card slot on the box 1x USB 2.0 port, 1x USB 3.0 port No serial/UART adapter (DEBUG header visible on PCB but not connected) Android 13 still working on EMMC ADB access with root What I tried: Built Armbian with BOARD=rk3528-tvbox BRANCH=legacy BUILD_MINIMAL=yes RELEASE=trixie Extracted DTB from Android boot partition, added to image Wrote image to TF card with dd Verified RKNS header at sector 64 - correct Tried replacing idbloader with one from our custom U-Boot build Original U-Boot on EMMC appears to ignore TF card completely Question: How to make original U-Boot boot from TF card? Or is there a way to install Armbian to EMMC safely while keeping ability to recover? Device AIDA64 info: Model: H96_Max_RK3528 Device: rk3528_box Hardware: rk30board Thank you!

Support for rotation is better in modern 6.18.y Linux. Fastest is to download image and try https://www.armbian.com/boards/roc-rk3399-pc But VPU acceleration in rotated screen might be a problem ... and you will need to generate Gnome desktop image to facilitate Wayland or no fun.

This week saw significant development activity across the Armbian ecosystem, with numerous enhancements to desktop environment support, including the addition of KDE Neon, KDE Plasma, MATE, and i3-wm, as well as improved branding and menu documentation. The desktop module was refactored for greater modularity and YAML-driven configuration, alongside fixes for theming and package removal tracking. Hardware support expanded with new device trees for NanoPC-T6 LTS Plus and Gateway DK, plus initial support for Arduino UNO Q (Qualcomm QRB2210) and additional USB Ethernet drivers. The build system received updates for kernel versions and distribution releases, notably bumping Ubuntu from plucky/noble to resolute. Automation and audit scripts were improved for reliability and scope, and documentation was updated to reflect the new tier model and branding. Overall, these changes strengthen Armbian's usability, hardware compatibility, and developer tooling.

I encountered the same issue. When I used the Orange Pi 3B image based on the 6.18 kernel, USB was not available, but when using the 6.1 vendor image, USB worked.

@Nick A Thank you！ That would be very helpful.⭐

@Sergioclr Search the forums for "PL2303HXA". I think it will work. After you compile your build, check build/cache/sources/u-boot-worktree/u-boot*; you should find root_key.pem there

Nice @Kevin su. my results with the eth0 working was similar to yours. but after an "ip link set down dev eth0" got those lower. whatever. Its alive after all!

Kernel 7.0 is out with broad hardware enablement and performance updates. Collabora contributed 227 patches from 24 developers, spanning major graphics work, multimedia fixes, and substantial enablement for Rockchip and MediaTek. View the full article

Question regarding to a post of yours: "Your root_key.pem needs to be in the u-boot root directory" As per instructions, I created the secure-boot.patch in ~/build/patch/u-boot/u-boot-aw but there is no root_key.pem in the u-boot root directory.

Yes, the pads are marked GND, TX and RX (underside)! I have an old USB-to-serial (DB9) cable adapter (PL2303HXA), will it work or I have to buy one like this?

I ran a speed test on my SSV6051. Here are the results: Idle Latency: 9.78 ms (jitter: 1.12ms, low: 9.33ms, high: 10.93ms) Download: 34.46 Mbps (data used: 23.6 MB) 52.01 ms (jitter: 6.52ms, low: 19.97ms, high: 109.64ms) Upload: 8.25 Mbps (data used: 12.4 MB) 99.47 ms (jitter: 26.37ms, low: 48.84ms, high: 491.13ms) Packet Loss: 0.0%

@Sergioclr Those unpopulated pads in the top-left corner are likely the UART (Serial) debug port. Check the underside of the board—are the pads labeled GND, TX, and RX there? The most reliable way to boot Linux on this box is to use a USB-to-UART TTL adapter. Without one, we’re essentially working blind.

Good afternoon. I bought a NanoPi R76s rev. 2 (3GB RAM + 0 EMMC). It works fine with the manufacturer's firmware. However, it doesn't boot on Armbian (26.02.1). I assume rev. 2 isn't supported. Is it possible to add support?

Parameter is visible in /proc/cmdline but has no effect — Rockchip DRM driver does not support the rotate parameter. Chromium flags (tested individually and in combinations): --disable-gpu-compositing — moved the line to the center of the screen --disable-gpu-rasterization / --disable-gpu-vsync — made it worse --use-gl=egl — no effect --enable-gpu-rasterization --enable-zero-copy — no effect --default-tile-width=1920 --default-tile-height=1080 — no effect --gpu-rasterization-msaa-sample-count=0 — no effect --force-device-scale-factor=1 — no effect --use-gl=angle --use-angle=gles-egl --use-cmd-decoder=passthrough — crashed Chromium CSS GPU optimization properties: Tested translateZ(0), backface-visibility: hidden, will-change: transform on the rotation container — no effect on the artifact. Chromium 132 upgrade: Installed chromium 132.0.6834.159-1~deb12u1+rkmpp from liujianfeng1994/chromium PPA. The vertical line remained, and video playback became unstable (freezing). Reverted to Chromium 114. Mesa upgrade to Ubuntu noble-updates 25.2.8: Removed Panfork PPA and installed standard Ubuntu Mesa 25.2.8. GPU fell back to llvmpipe (software rendering) — no Panfrost support for Mali-G610 in standard Mesa. Display showed tearing in the center. Reverted to Panfork 23.0.5. Conclusion: The artifact appears with any rotation method (CSS, xrandr, kernel) and persists across Chromium versions and various GPU flags. This strongly suggests the issue is in the Panfork Mesa / Panfrost compositing layer when handling rotated output on Mali-G610. Has anyone encountered this issue? Is there a known fix or workaround? Would upgrading to Panthor (with kernel 6.10+ or the 6.1 backport) potentially resolve this? Any help would be greatly appreciated.
