Greetings, I have installed your wiringpi-python on our Nano Pi M4 as instructed on http://wiki.friendlyarm.com/wiki/index.php/WiringPi-Python_for_RK3399. All went well with the installation. However, when trying to execute wpi.wiringPiSetup(), I get the following error: Oops: Unable to determine board revision from /proc/cpuinfo -> No "Hardware" line -> You'd best google the error to find out why. This is strange because there is no "Hardware" line in proc/cpuinfo on any Linux system in our organization. Can you please explain what is the way forward. Or is there a python 3 alternative to wiringpi that is as detailed? Or is there an update to WiringPi-Python for the Nano Pi M4 running rk3399-eflasher-friendlydesktop-bionic-4.4-arm64-20190308.img We are at a standstill due to this as you must be aware that without "wiringPiSetup()" working, the whole wiringpi-python library is useless. Thanks in advance iomari

I tried this image : Armbian_5.89.190626_Nanopim4_Ubuntu_bionic_dev_5.1.0.7z, but the MAC address changes on every reboot, and so the IP address changes (auto IP).

Hi all, any recommendations for a ~ 5" monitor for the M4 ?

I'm trying to build a linux from source on a RK3399 nanopi-m4.

Plug the UART cable and power on the board.

Hi, I'm wondering if the NanoPi M4 can be made to work with a PiTFT 320x240 screen? When I set up the /dev/fb0 device and write to it, the display simply stays black/white (each time I write to the display only the shades change). NanoPi M4 has a different GPIO set-up from Raspberry Pi 3b+ (which PiTFT works with). Is there a possibility that the NanoPi M4's GPIO could be rewired in a way that it would support the PiTFT? E.g. Tinkerboard runs under RK3288 (vs M4's RK3399) and has the same GPIO layout as the RPi 3B+, so it could maybe be made possible?

I need one more component working. 3D and OpenCL. Has anyone successfully installed Panfrost on a RK3399 board ? Update! I manged to build the Panfrost X11 driver. Here's how I did it: https://panfrost.freedesktop.org/building-panfrost-mesa.html Before you create the build directory update the meson_options.txt file change platforms from auto to x11 change dri_driver from auto to swrast change gallium-drivers to panfrost cd to the build directory meson .. . -Ddri-drivers= -Dvulkan-drivers= -Dgallium-drivers=panfrost -Dlibunwind=false --prefix=/{wherever you want} ninja install before you start a program export LD_LIBRARY_PATH=/{wherever your path is} glmark2-es2 When I get home from work I will test further. I will update later. I wanted to post just in case anyone else wishes to try it. I got to go to sleep, work tomorrow.

Hi, I'm running Armbian Bionic 4.4 (Linux nanopim4 4.4.190-rk3399 #5 SMP Sun Sep 1 23:12:43 CEST 2019 aarch64 aarch64 aarch64 GNU/Linux) on a NanoPI M4 and I'm trying to enable HDCP on the HDMI output.

Hi Folks, I'm testing the M4 board with Armbian Buster, I'm having the following problems with the GPIO: How can I use gpio without root? I've checked and there isn't a /dev/gpiomem device so I can give permissions to other users. Only a few of the GPIO pins can be set. Most of them don't show up as configurable through gpio readall. A few of them show as ALT and although I can change their mode (input / output), I cannot change/read their value, it seems those are shared with i2c-3, so this can be the problem, but I don't know how to disable i2c-3 and use them. Also, can all the 6 cores work at the same time? Or the BIG.little architecture enforces choosing between the fast or the slow ones? Best regards,

Hi, at first thank your for your great work! I've successfully created an wifi hotspot on nanopiM4 using "Armbian_5.95_Nanopim4_Debian_buster_default_4.4.190" with armbian-config utitlity. After the tool is finished I can connect to the hotspot and it shares the internet connection.. However - when I reboot the system the hotspot still works and I can connect but I have no connection to the internet anymore. The nonopi itself has connection to internet, I checked that. Do you have any sugestions? Thank you in andvance! Christian

Hello, I'm using Nanopi M4 installed Armbian Buster. It works like charm but I found a strange behavior of the system. In htop all cores are displayed as little core. but when I checked actual clocks in /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq big cores are doing well (up to 1.8GHz). htop result: lscpu results: Architecture: aarch64 Byte Order: Little Endian CPU(s): 6 On-line CPU(s) list: 0-5 Thread(s) per core: 1 Core(s) per socket: 3 Socket(s): 2 Vendor ID: ARM Model: 4 Model name: Cortex-A53 Stepping: r0p4 CPU max MHz: 1800.0000 CPU min MHz: 408.0000 BogoMIPS: 48.00 Flags: fp asimd evtstrm aes pmull sha1 sha2 crc32 CPU SOCKET CORE ONLINE MAXMHZ MINMHZ 0 0 0 yes 1416.0000 408.0000 1 0 1 yes 1416.0000 408.0000 2 0 2 yes 1416.0000 408.0000 3 0 3 yes 1416.0000 408.0000 4 1 4 yes 1800.0000 408.0000 5 1 5 yes 1800.0000 408.0000 Is this result normal?

Hi, I need to use callback function in Python3 on my NanoPi M4 but I can't, so it is very nice if anyone can help me with this issue. So far I've tried the function with wiringpi as shown command bellow but this doesn't work at all, that generates some errors and after that my command in /usr/bin/ doesn't work .... I can use other functions in wirignpi so guess something is wrong with only this function... Is there any way to use callback function with NanoPi M4, for example using other modules or something Thank you,

I have Armbian running on my NanoPi M4 Everything is fine but.............. I have massive problems with pulseaudio Im not able to get the sound working So i tried to deinstall pulseaudio and install Alsa After that i dont see anything regarding sound in settings menu or on the taskbar For unknown reasons the wallpaper has resettet Anyone who has a solution ?

I uses my NanoPi M4 as a cheap ARM64 kvm host, and I need a newer kernel since the legacy one is kind of broken in terms of KVM. But Wi-Fi is not working in dev kernel for quite some time, I found a temporary fix for that: # cd /lib/firmware/brcm # mv brcmfmac4356-sdio.bin brcmfmac4356-sdio-orig.bin # ln -s ../rkwifi/fw_bcm4356a2_ag.bin brcmfmac4356-sdio.bin # ln -s ../rkwifi/nvram_ap6356s.txt brcmfmac4356-sdio.friendlyelec,nanopi-m4.txt Then reboot, Wi-Fi will be back.

I'm trying to install wiringpi by following the instruction given here https://github.com/Pavelectric/WiringPi_M4. Most of the steps that I followed worked fine but when I do the very last command below, I get a following error, I googled how to deal with this kind of error, and some people tell that 'ContextualZipFile' in archive_util.py doesn't have to be installed so I just need to comment that out. Although, I couldn't find '/usr/local/lib/python3.6/dist-packages/setuptools-33.1.1-py3.6.egg/setuptools/archive_util.py', I did that comment out solution to the all files below, which I got by doing find-command-research Now I don't know what to do here... It is very nice if anyone can help me get out of this darkness... Thank you,

With the stable images for NanoPi M4 I see CPU speed is limited to 1.8Mhz, whereas with nightly builds I get up to 2GHz for the fast cores. I would rather like to stay with stable image, also because boot time is much longer with nightly builds. What is the easiest way to enable up to 2GHz CPU speeds with stable build? JB

Hi all, I have motion installed and a FriendlyElec camera connected to my board, my problem is, the camera is not detected by motion - what do I need to do to configure the camera / motion ?

Hi, I'm currently facing strange problems... I'm using NanoPi and operate some USB devices with it. Since I wanted to know the total power consumption of the system, I measured current which flows into NanoPi from the outlet. The current during while the camera working was very nice (about 1A) so I shut the pi down. Then, I found that the total current value gradually rose up from about 1A to 1.5A. This seems to be so strange because when it gets shutdown, the power should be off as well, and the pi only needs small amount of power just to light the red LED. I tried a few times but the result was always same... I can't understand the reason why this happens, does anyone have ideas to explain this phenomena?

Hi all, I have a Friendlyarm nanopi M4 running armbian, I have tried to install dotnet core without success - anyone here managed it ? I followed a tutorial but when I get to the apt-get install part I see this error Couldn't find any package by glob 'dotnet-sdk-2.2'

When can I expect a final Armbian image for the Nanopi M4 ? I'm eagerly awaiting it and many others will surely be too The image of friendlyarm is simply an imposition You have the feeling of being on the road with the handbrake on.

Hi all, does anyone know of a good reliable way to flash an image to a FriendlyElec type eMMC card, originally I used their microsd adapter but for some reason my PC / Transcend adapter doesn't recognise them anymore.

Hello, yesterday i see that the SATA Hat for the Nanopi is available now is it possible to install Armbian on a SSD when i use the Sata Hat ? Or is the EMMC or SD Card required for the OS ?

Hi all, I'm trying to get Bluetooth working with the M4 ( installed it via armbian-config ) but on checking the status I see this

We are evaluating many boards for Industrial purpose, often fails to pick the right one, form Raspberry PI to other boards, including Tinkerboard. We aim to bring the cost of the SBC to 60 to 100 USD, mainly used for Industrial, within 0-70 Deg C. In fact, I have posted similar questions to find out answers, including Rock64, Olimex etc. Olimex seems to be supporting Industrial temperature, but their A64 seems to have less USB ports. Many SBCs vendor advertise their board for Education, Hobby purpose, I see Nano PC boards, they advertise for robotics, Industrial purpose http://wiki.friendlyarm.com/wiki/index.php/NanoPi_M4 with WIKI stating working temperature is 0-70 Deg C, their product page suggest 0-80 deg C. We yet to order one Nano SBC, anyone had exposure with NanoPI M4 boards, readiness for Industrial application? More importantly, it support Raspberry PI pin compatibility and additional PCI and 2 USB hosts in GPIO. I am trying to understand Olimex vs Nano PC for industrial use, excluding -40 to +85 range

Hi all, has anyone here got a camera to work on the M4 running Linux - I know they work with Android but what a waste of a board putting Android on it
