First many thanks for your reply. I can understand resource problems you mentioned. That's why I tried to help me alone during several days as a lot of people do. My initial problem was accelerated video. A little bit later I discovered BT issue. I was thinking BT will be easier to solve but hard enough for low experienced ARM people like me. I'm software developer and I tried to build Mali driver from official open sources with recent kernel found in Armbian. I quickly understand that Mali sources are not ready for such recent kernel. A lot of kernel refactoring like: timespec, Y2K38 bug, and more cause Mali sources unable to build. I fixed some Mali code to progress but I need to fix more stuff to obtain a mali.ko fully functional. ARM world is a new world for me: I have a lot to understand to progress. DTB and so on... If you have any recommendations (tuto, docs, ...) to help to progress as quick as possible, don't hesitate to give me some URLs

I just test this: https://forum.libreelec.tv/thread/20461-libreelec-9-0-2-for-nanopi-k2/ Bluetooth is working fine: I successfully paired my device with Nanopi K2 embedded BT. Video is accelerated with mali.ko Sadly, LibreELEC purpose is just to execute Kodi: it is not a full feature OS. So, what's wrong with Armbian? Am I missing something to configure? Is it a known bug?

Hi, I recently installed a fresh Armbian and did some tests. I noticed two major problems: Video is not accelerated: it is absolutely unusable with kodi Bluetooth seems absent (missing from DTB? other reason?) Please find below execution outputs of some commands: root@nanopik2-s905:~$ cat /etc/armbian-release # PLEASE DO NOT EDIT THIS FILE BOARD=nanopik2-s905 BOARD_NAME="NanoPi K2" BOARDFAMILY=meson-gxbb BUILD_REPOSITORY_URL=https://github.com/armbian/build BUILD_REPOSITORY_COMMIT=b9814056 DISTRIBUTION_CODENAME=focal DISTRIBUTION_STATUS=supported VERSION=20.11.3 LINUXFAMILY=meson64 BRANCH=current ARCH=arm64 IMAGE_TYPE=stable BOARD_TYPE=conf INITRD_ARCH=arm64 KERNEL_IMAGE_TYPE=Image root@nanopik2-s905:~$ root@nanopik2-s905:~$ hciconfig root@nanopik2-s905:~$ root@nanopik2-s905:~$ rfkill list 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no root@nanopik2-s905:~$ Is there any people with same problem on their boards? Any idea on how to fix bluetooth feature? I read all 7 pages but I did not find anything useful to solve my problem. Another information, I boot original image from friendlyarm and bluetooth is up and running so my board is physically good.

Thank you I will test that...

I performed following steps: root@desktop:~# cat Armbian_5.75_Nanopik2-s905_Ubuntu_bionic_next_4.19.20_desktop.img > /dev/sdf root@desktop:~# dd if=/dev/sdf of=u-boot_k2.img bs=1M count=4 root@desktop:~# cat Armbian_5.77_Aml-s905_Ubuntu_bionic_default_5.1.0-rc1_desktop_20190407.img > /dev/sdf root@desktop:~# dd if=u-boot_k2.img of=/dev/sdf conv=fsync bs=1 count=442 root@desktop:~# dd if=u-boot_k2.img of=/dev/sdf conv=fsync bs=512 skip=1 seek=1 root@desktop:~# vi extlinux/extlinux.conf add line: FDT /dtb/meson-gxbb-nanopi-k2.dtb SD card boots perfectly. Below, output of uname -a Linux aml 5.1.0-rc1-aml-s905 #5.77 SMP PREEMPT Sun Apr 7 12:55:48 MSK 2019 aarch64 aarch64 aarch64 GNU/Linux I noticed this image doesn't contain mali drivers so I don't expect a smooth Kodi GUI... I will play with it anyway and achieve some tests. If you think about some tests you would like I perform, feel free to ask...

I planned to use Armbian_5.75_Nanopik2-s905_Ubuntu_bionic_next_4.19.20_desktop.img to prepare a working SD card and then to grab u-boot from. But I noticed this image contains only one partition. Armbian_5.77_Aml-s905_Ubuntu_bionic_default_5.1.0-rc1_desktop_20190407.img image contains two partitions. Is your procedure always applicable in such situation?

Yes! My K2 is ready to test images: I have several SD card so no problem to rewrite them from scratch... Waiting for your images...

Hi, I am trying Armbian on NanoPi K2. I use Armbian_5.75_Nanopik2-s905_Ubuntu_bionic_next_4.19.20_desktop.img. All is working great except video driver performance... I installed Kodi and sadly its GUI is really really slow: unusable at all Playing a video in full screen with firefox is too slow also... I suspect a software issue on Armbian because I already successfully tested a version of LibreElec running very smoothly. LibreElec runs mali.ko kernel module which handles well GPU of NanoPi K2. How to tweak Armbian to handle GPU correctly? I am available to test and to help to improve Armbian support of NanoPi K2 board. Feel free to ask... Thank you for your attention
