I just checked at my ROCK5B running Armbian userspace: # sudo apt update # sudo apt list -a linux-headers-*current-bcm2711 linux-headers-current-bcm2711/trixie 26.2.1 arm64 linux-headers-current-bcm2711/trixie 25.11.2 arm64 linux-headers-current-bcm2711/trixie 25.8.2 arm64 linux-headers-current-bcm2711/trixie 25.8.1 arm64 linux-headers-current-bcm2711/trixie 25.5.1 arm64 linux-headers-current-bcm2711/trixie 25.2.3 arm64 linux-headers-current-bcm2711/trixie 25.2.2 arm64 linux-headers-current-bcm2711/trixie 24.11.1 arm64 linux-headers-current-bcm2711/trixie 24.8.2 arm64 linux-headers-current-bcm2711/trixie 24.5.1 arm64 linux-headers-current-bcm2711/trixie 24.2.1 arm64 So you can install them with: # sudo apt install linux-headers-*current-bcm2711 You will get the latest if you do not select explicit version 6.18.9, I got 6.18.10 as that seems to be the latest now. Armbian also has edge and legacy, but for normal release all 64-bit Raspberry Pis is named 'current-bcm2711', which should be the equivalent of 'rpi-v8', which is the normal 4k pages downstream kernel in Raspberry Pi OS 64-bit. It might be you originally had the dedicated rpi5b installation, so you simply had not gotten the headers maybe. Armbian has no 16k pages kernel, if you want that, you need to build yourself, but note that this comes with quite some of issues, many people are not aware and cannot fix issues due to that. See 2+ years of trouble w.r.t. that on RPL forums. I do not use Ubuntu based Armbian, but Debian based, but should not matter for that kernel packages as those are Armbian on top of either distro.

Hi everyone, I’m working on an RK3568-based platform (Yocto build, Rockchip BSP) and I’ve reached a blocker regarding OP-TEE / Trusted Application (TA) development. Anyone knows how to get RK3568 + Linux + OP-TEE source/build path Rockchip vendor SDK with RK3568 OP-TEE source a repo showing rk3568 + optee_os + TA dev kit for

@ssdm2nvme Hi, whats up? I tried everything you recommended, including following some other tutorials beforehand, but I still can't get past the TV box's "BIOS" screen. It keeps restarting repeatedly, and I can never actually access the system. Do you have any idea what it could be?

Hello! I have a follow-up question about installing Armbian on a Raspberry Pi 5, and hopefully this is a good place for it. Perhaps this belongs here instead: I just installed the Armbian/Gnome version for Raspberry Pi "4b", as mentioned above, for my Raspberry Pi 5. The OS booted fine and is running. However, I'm trying to install some additional software (specifically this: https://github.com/sunfounder/pipower5/tree/main) and I'm getting errors related to installing the right version of `linux-headers`, the output of `uname`, and possibly the `bcm2711` vs. `bcm2712` CPU. The original error was: ``` Error: E: Unable to locate package linux-headers-6.18.9-current-bcm2711 E: Couldn't find any package by glob 'linux-headers-6.18.9-current-bcm2711' E: Couldn't find any package by regex 'linux-headers-6.18.9-current-bcm2711' ``` When I searched for the available packages, I found the following "closest" options: ``` linux-headers-current-bcm2711/noble 26.2.1 arm64 [upgradable from: 26.2.1] Armbian Linux current headers 6.18.10-current-bcm2711 linux-headers-current-bcm2712/noble 24.11.1 arm64 Armbian Linux current headers 6.6.63-current-bcm2712 ``` At this point, I realized that the installation scripts were pulling the kernel version from the output of `uname`: ``` denbro@rpi5b:~$ uname -r 6.18.9-current-bcm2711 denbro@rpi5b:~$ uname -a Linux rpi5b 6.18.9-current-bcm2711 #1 SMP PREEMPT Mon Feb 9 10:54:02 UTC 2026 aarch64 aarch64 aarch64 GNU/Linux ``` My two main questions are: 1. Why is the proper linux header not available? My understanding is that, in principle, `linux-headers-$(uname -r)` should always be available. 2. Should I be concerned that my linux kernel thinks it is using the bcm2711 CPU? That's the Pi 4 CPU, but my raspberry pi 5 has a bcm2712. Should I install the version of armbian for the Pi 500? Two additional notes - 1. The Sunfounder software I mentioned above installed without issue on the same device running Raspberry Pi OS Trixie. 2. I originally tried to flash an SD card with Armbian using Raspberry Pi Imager, and it wouldn't boot; the device turned on, and printed a bunch of startup output, and then shut off. After confirming that the SD card worked, I switched to using Armbian Imager to flash the SD card and that led to my current state. ``` denbro@rpi5b:~$ neofetch ##### denbro@rpi5b ####### ------------ ##O#O## OS: Armbian 26.2.1 noble aarch64 ####### Host: Raspberry Pi 5 Model B Rev 1.1 ########### Kernel: 6.18.9-current-bcm2711 ############# Uptime: 1 hour, 25 mins ############### Packages: 1200 (dpkg) ################ Shell: bash 5.2.21 ################# Resolution: 1280x800 ##################### Terminal: /dev/pts/1 ##################### CPU: (4) @ 2.400GHz ################# Memory: 691MiB / 3983MiB ``` Let me know if there's any other information I can provide, and thanks in advance for any guidance!
