How to use GPIOS like the FriendlyELEC's official system? Wiringpi does not work on Armbian, can you adapt the Armbain system of Nanopc T4 to Wiringpi?

rk3588-pcie_bifurcation_2x2-uboot.patchrk3588-pcie_bifurcation_2x2.patch Attached are two patches I've prepared. One for uBoot (to correctly recognize split pcie3x4 to two independent controllers, pcie3x4 and pcie3x2), and one for DT of NanoPC T6. This basically allows you to use trimmed-down bifurcation adapter. The adapter in question must be trimmed down/cut to fit on the back of the board. Tested with 2x NVME, and 1xNVME and QCNFA765 wireless card. I'll post photos later once I'll disconnect the board again from my setup. BEWARE!!! If you'd plan to use more than one ath11k wireless card, you'd need QRTR patch. Since the SBL …

Hello all I have broken my installation when I tried to install the kernel 6.1 my current kernel 5.10.160-legacy-rk35xx. My nanopc t6 do not start. My installation is on EMMC and start on it. Could you please help me to recover it ? I have a backup file from OMV but I don't know how to push the backup to the EMMC? other possibility I guess copy the boot folder backup to EMMC boot folder but I do not know if it is enough. I really appreciate an help furthermore a clear turial could help evryone to recover an installation on EMMC memory. Thanks in advance for your support.

Hello, I tried to install Armbian on my NanoPC T6, but when I boot it and look at the dmesg, I see some errors related to the emmc module. The emmc module is not the problem; I have tried different operating systems, and I don't encounter these issues. Here are the logs: https://paste.superkali.me/dajiqaloxa.yaml Thank you in advance.

Hello I would like to know if it is possible to have 2 partions on the emmc. Indeed My emmc have 256go for only the os armbian with OMV (2.5go only used). I would like to have for example a boot partition with size of 50go and an other partition for my data (200go). However when I use armbian-config the full emmc is formated. If a solution exist could you please share with me the solution. Thanks in advance for your support.

Dear all I have a nanopc T6 with kernel 5.10.160 bullseye and omv 6 EMC 256gb avec NVME I would like to pass on omv 7 with bookworm. I found this command which change all automatically and keep the configuration. "omv-release-upgrade" Could you please confirm that this command could be used with armbian or an other metod exist ? Thanks in advance for your support.

Hello, I have installed the currently provided image "Armbian_24.11.1_Nanopct6_bookworm_current_6.12.0_minimal.img.xz" on my NanoPC-T6 (not LTS). Unfortuantely the only one USB3 port is not working. So no local access is possible and no external USB storage device can be used. I wonder if no one else has such problem reported yet since 3 weeks now (released 2024-11-21). The USB3 port is working with the FriendlyELEC image (rk3588-sd-debian-bookworm-core-6.1-arm64-20241112.img.gz), so maybe there is a small problem with a kernel module or the device tree. If someone can guide me to a starting point for investigation, I can do some debugging. I have little…

Hi, since latest upgrade to new kernel 22.02 stable the system becomes unstable. There are issues writing to mmc2 and "EXT4-fs (mmcblk2p1): Remounting filesystem read-only". This does not allow most of the apps to work properly (e.g. openmediavault stops working) I tried to switch back to previous kernel version through armbian-config but that does not work too Pls help. Thanks

Hi, I try to get my NanoPC-T4 a second life. Therefore I want to (re-) install Armbian but I'm stuck Andi don't know why. I uses USBFlasher to flash the minimal Armbian on it (tried compressed and uncompressed) but the green blinking light indicates me, that he found no bootable device. I tried different images as well. Also differen SD cards, even DietPi image, always the same. The only thing which runs instant is one of the eflasher Images of FriendlyARM. I also tried to change the image that the eflasher writes to the eMMC (by copy the uncompressed .img file to the SD card and renamed it to armbian.raw and changed the config file as the wiki said)…

Hi. I'm new here and have a small issue. Situation is: I'm using the T4 board for an amateur radio repeater controller. The repeater works in an unmanned relay station 10 kilometers from the my home. To have access by remote even if the boot hangs for some reasons (maintenance mode), I have connected the debug uart (ttyS2) to a serial-to-IP adapter to have access anyway. Because the IP adapter cannot set up to 1.5 MBps, I have reduced the speed down to 115 kbps by changing the kernel argument in the boot.cmd from console=ttyS2,1500000 to console=ttyS2,115200. That worked well with the Armbian 5.69 stretch 4.4.167 kernel. Now I have made…

Hello, i'm using the NanoPC-T4 with Armbian Bookworm (23.8.1 with Linux 6.1.63-current-media) Kernel and Mainsail/Klipper is running on in smooth and gently. Since i want to record timelapse videos, i've decided to buy the orginial "FriendlyELEC Cam1320 PI Camera Module" based on the OV13850.

Hi everybody, I am currently facing some struggles with the nanoPC-T4 recently bought to run armbian. When I got the board, I was able to run android default installed OS, but also armbian from a SD card. But along the way, I decided to install armbian on an NVMe SSD memory to prevent running the OS from the SD card, anyway ... That when I started playing to with the kernel build, u-boot, flashing the emmc etc .. I tried couple of times using the rockchip tool : developtool in MASKROM to play with the EMMC because I couldn't boot from the SD card, and wanted to start with a clean emmc, but every time the tool had to execute a libusb_bulk_transfer, …

Has anybody successfully used the USB type-c displayport of the nanopc-t4? How do you configure it? It works on the images provided by friendlyelec, so, I guess it is just a config/install issue ?

steps to reproduce: 1. download official stable images and extract 2. write either image (both fail in same way) to sdcard: Armbian_5.91_Nanopct4_Debian_buster_default_4.4.179.img Armbian_5.90_Nanopct4_Ubuntu_bionic_default_4.4.179.img 3. boot sdcard -> works fine 4. run armbian-config -> firmware update 5. (also tried "apt update && apt full-upgrade", same result) 6. reboot -> boot loop happens every time, either the ubuntu or debian versions of armbian. no changes made after booting beyond just doing the update. reliably boot loops (it makes it to booting the kernel, then the board restarts after a while of no output) …

Hi, community! I wish you have a nice day! Started investigating why do I have problems trying to hear something from headphones. So, I believe there is something about HDMI audio codec related to panfrost, attached you will find info about. I guess this will be useful to catch bugs. I'm 73 years old, started on computers on NCR Century 100 as field engineer. From those years to now, a long development has brought to life.... Cheers, and many thanks to you! dmesg112222.txt armbianmonitor112122.txt

Hello all! I have a NanoPC-T4 and I'm currently using Android 8.1. I suppose I could flash Ubuntu to try this, but before that, here goes. I'm trying to use a USB 4G dongle with it. I get no recognition of the device. No RNDIS or any notification at all. Fresh install. Any ideas? Also, has anyone tried to come up with a method of root for android on this device? It's a super cool sbc! Thanks!

I've built everything into the kernel that I can think of: Device Drivers ---> [*] USB support --> [*] USB Type-C Support --> ** built everything other than alternative mode / display port drivers [*] PHY Subsystem ---> ... [*] Rockchip TYPEC PHY Driver Nothing seems to get it working (other than using the legacy kernel). If I plug in a USB type-c ethernet adapter, the light stays on solid but nothing shows up under lsusb.. I'm not sure what else to try. Any help would be appreciated.

So I noticed my NanoPC-T4's will not boot an image made with the latest armbian build script.

FriendlyELEC sells an 11.6inch eDP FHD LCD Display with Capacitive Touch for the nanoPC-T4. I'm trying my hardest to get it working with Armbian. Unfortunately, Armbian doesn't seem to detect the display: root@nanopct4:~# xrandr --listmonitors Monitors: 0 It works in the stock lubuntu image they provide so I'm trying to gather as much configuration information as I can from lubuntu to see what I need to do to get it working. I want to try a few different experiments.. I have a kernel.img file from lubuntu that I'd like to try booting with Armbian but I don't understand uboot very well and simply copying the kernel.img file to /boot under the same name as the e…

I've recently switched my FriendlyElec NanoPC-T6 to use the Armbian Linux v6.12 server image, built on the 24th of May 2025. Booting of SD works fine, but when installing to the eMMC chip some I/O errors can be found in the kernel logs: [ 151.814773] I/O error, dev mmcblk0, sector 176 op 0x0:(READ) flags 0x80700 phys_seg 10 prio class 2 This happens when under heavy I/O load - e.g. performing an apt upgrade. I ran badblocks over the entire eMMC chip without issue - but that puts a much lower strain on the eMMC. Therefore, i'm convinced that the eMMC chip itself is fine. Poking around a bit, this seems to be because the A3A444 eMMC chip whi…

On the LTS version of this board, there is no other chance than to run the vendor-rk35xx kernel if you want to see something on a screen. I noticed strange behaviour when this SBC was attached to a 2k QHD screen with the latest vendor kernel. Display size was limited to FullHD instead QHD and Firefox were crashing. When I switched from desktop to terminal I saw the top left corner of the QHD terminal cut to the size of FullHD which was quite a problem because I could not see what I was writing. Today I tried kernel downgrade from 6.1.75 to 6.1.43-vendor-rk35xx and now I can see QHD on QHD and the Firefox stopped crashing. Hopefully, they will patch the ke…

I built up a NanoPC-T4 with a 240GB NVMe. I am using the supplied heat sink and the black metal case that FriendlyArm sells. While I was copying an image over I got a board failure. A reset and power cycle didn't work. The stat light no longer shows activity. Just power.. that is all. Amazon was great and replaced the board. I am in the process of backing up my NVMe. After the backup I will run an OS install and restore the image. Has anyone else ran into this ? The black metal case isn't hot enough to burn my hands.. it's just very warm to the touch,.

Trying to sync latest beta release of Geth Ethereum client and it's filling ram till process crashes. Apparently setting a swap file helps - but sudo swapon -show says /dev/zram1/ 1gb partition already set up... I was going to set up a 4gb swap file on the nvme - what to do? Thanks for any advice.

Hi, community. I have set up this device from which I'm writing this, installed Armbian from SD card, by sweeping out original FriendlyElec images from the FriendlyElec's partition, so I wiped off the Android and Ubuntu, and copied on it the Armbian image, which appeared with the title "RAW". Booted and installed fine. It works. From armbian-config I managed to boot from an USB Toshiba 1Tb disk. To this part, I have a little but efficient linuxPC, ¡¡¡THANK YOU!!!. I'm trying to compile binaries of STM32, or Arduino devices, comment this to tell details only. Every 5 to 8 bootups, it didn't recognize the USB drive, and dumps a series of Hex data, divided in bunches. S…

NanoPi-M4 will be cheaper and same form factor as RPI 3.

Hi all, This has confused me! I have an old copy Armbian_20.02.7_Nanopim4_buster_current_5.4.28_desktop.7z which works fine. Any SD cards I put it on using Balena Etcher works. Any of the latest versions simply won't boot. The only difference appears to be the XZ file format. I extracted one of the later ones using 7Zip and then Etcher to flash and as expected it mad no difference at all. Has something been done to the V1 firmware from the V2 that doesn't work or firmwares containing the wrong naming etc? Help!

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?

Hello, Recently I tried to make pwm control on my Nanopi M4. Beside the PWM pin on the 24 pin connector (the one which actually controls the voltage output on 12V 2 pin connector for fan), I wonder if it is possible to use GPIO pins on the 40 pin connector as pwm pins to control fans. I tried to set pwmchip0 and literally checked every pin by connecting the wire to each one of them but I couldn't find that any othe these GPIO react on any settings I made on pwmchip0 pwm0. Does anyone know how to do this? Best Regards.

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, I want to do a NAS RAID(4,1) with the M4 with SATA hat. This thing is f... damned fast with SAMBA. I meassured 60MB/s with a 1.5TB 2.5" drive I had just laying around. OK, I forgot to mention that I installed Armbian. It's been three years since my last attempt to build a useful PC with AARCH64 and many things happened meanwhile. Looks like the time has come finally. (To say good bye to x86 and Windows.) Can someone point me to a direction before I gonna buy four SSDs?

I have a nanopi m4 and I want to use the /dev/ttyS4 (UART4) for communication, but only the RX is working, and the TX does not, but when I set the GPIO nr. 40 (the TX pin) to output through sysfs I can change the voltage level from high to low and back... Please help, what am I missing here, that I can not transmit anything ? I am using the latest friendlycore.

Hi all, has anyone managed to get wifi working on the Buster image for M4 v 1 ? Works perfectly with Bionic but I couln't connect at all on the Buster image ( eth0 on physical cable was fine ), using armbian-config lists available networks but is unable to connect ( which is what the error message is )

Hi guys. I've received the NanoPi M4 V2 today. I tried Armbian images for the M4 on SD and eMMC. None boot. So I tried the RockPi4 images since that's got lpddr4 too. That works. Of course no on-board wifi since another chip. So my guess is the lpddr4 isn't supported by the uboot for the M4. It is a nice board. I've got the metal case with NVMe hat too. Looks all very nice. But a bit impractical if you need to acces eMMC. Cheers

What am I missing ? Just flashed Armbian_20.11.7_Nanopim4v2_buster_legacy_4.4.213_desktop on a SD card and the NanoPi does not boot. I get a steady red led and no flashing green and nothing on the HDMI. I don't get that problem when Flashing the eMMC...the problem is that I don't have that eMMC anymore and I am looking for a way to install Armbian on my NanoPi's NVMe SSD drive from the SD card. Any hints would be appreciated.

Hi all, today I used rsync to copy some music files from an attached USB drive to my NVME M2 SSD drive and noticed the Nanopi was getting very hot. I have it housed in an official metal case with a fan. The fan didn't come on despite the temperature of 80 + , the case was very hot to the touch. I turned it off in the end in case it got damaged. Any suggestions appreciated. The board is running the latest Buster from here.

I've recently upgraded my NanoPi M4 V2 to Armbian_25.2.1_Nanopim4v2_bookworm_current_6.12.13_minimal.img.xz and since that, I have been getting random crashing of it, to the point that I have to manually power it down and up again to get it back running again. The only thing I've noticed is that this normally happens when there is intensive disk usage (like downloading a bunch of docker images, or when downloading large files from the internet).

My NanoPi M4V2 wont boot. It has a solid red light no green at all. I cant access it with SSH. I went through the troubleshooting checklist available for the NanoPi in regards to the red light. Nothing was solved. I tried different SD cards with different types of images and different types of burners. Nothing works. I know that the SD cards, images, and burners are not the problem cuz I tested it on a Raspberry Pi with no problems.

Hi, I own a NanoPi M4 and I am wondering how to get the USB OTG working. I would like to set up Ethernet via USB OTG on my NanoPi M4. The only reference I can find is with https://vjordan.info/log/fpga/nanopi-neo-usb-otg-with-armbian-mainline-4x-kernel.html and I want to know if the steps are similar for NanoPi M4.

I just bought one NanoPi M4 on FriendlyArm Black friday, I was wondering if the Raspberry Pi Oficial 7" display works with the DSI connect on NanoPi M4?

Hello, I was wondering if it is possible to disable both LEDs on this board or, at least, the green (stat) one. Also I was trying to remove wifi completely and I can do: iwconfig wlan0 txpower off ifconfig wlan0 down systemctl disable wpa_supplicant But not sure if it's possible to remove the driver from the OS and what other unnecessary software I can remove. Thank you in advance.

My nanopi m4b has been showing slowness problems that I believe to be caused by the ethernet, I access a site inside it that has a camera stream and sometimes it is slow, and now the connection via ethernet completely stopped working, I looked for something in the logs but I didn't find anything that could indicate the problem, I can access my site over wifi

Hey, I am using a Nanopi M4v2 with a Satahat as server for openmediavault and plex. Since I got a lot of freezes/crashes (every 24-72h, the Nanopi lost the connection, and the green LED isn't blinking anymore) with "Armbian 20.02.7 buster current 5.4.28" on a SD-Card. I plugged a SSD in and used the nand-install script with a clean installed SD-Card. But this doesn't help, the problem is still there.

I have an FriendlyElec M4v2 board without eMMC card. (so i only use SD card) I tried this image: Armbian_21.02.1_Nanopim4v2_focal_current_5.10.12_desktop.img I Wrote to SD with Balena Etcher. After the new installation I turning on my board, I see my two attached .jpg file contents on the screen and after my screen flashes and immediately turns off my monitor (with no signal text on the screen) and if then I can only see Armbian again if I turn my monitor off and after on. So the Armbian is booting in the background, just need an HDMI channel refresh with a monitor physical off and after on. Then I installed all updates ('apt up…

Few days ago i saw an issue after i added rule to auto-reboot device once a day, every time it's reboot it's losses connection with sata hat - no more sata controler after typing "lspci" and some nasty output after "dmesg | grep pcie". I tried reboot manually, when i reboot just after powering on (like up to 2 min), pcie goes back up and there is no issue, but if device stay on for longer and i reboot it then there is pcie training issue and mervell sata controller don't get recognized anymore, further rebooting don't fix the problem, i even tried to connect drives power straight through SATA Hat, but it had changed nothing. The only fix is to shutdown device instead …

Like the title says, when I open armbian-config on my brand new NanoPi M4N2 I don't see a "Hardware" entry in the menu... is this expected? Only reason I wanted to access is to ensure I disable WiFi as I am only using Ethernet. For the record, I'm powering it with a 5V 4A PoE adapter, using a Samsung SD-card flashed with Armbian_20.05.7_Nanopim4v2_buster_current_5.4.49.img. I'm using a 256GB Sabrent M.2 NVME SSD as the main disk (configured via armbian-config), so the SSD card is for initial booting only.

Is there an issues page relating to the M4V2 and Armbian Focal. I'm testing it and I have a few strange things happening with NFS and network but I was wondering if there as a known issues or a general topic regarding this board and this Ambian build because searching for nanopi-M4V2 Focal... is not a good idea. Thanks

Hi, My Nanopi M4V2 often gets unresponsive. I cannot reach the nginx server when that happens. SSH also stops working. The red led is on, and the green led stops blinking when it happens. Any tips on what I can try? Running: Armbian buster with Linux 5.4.49-rockchip64 with heatsink from EMMC. http://ix.io/2u4O

Hello. I'm using a NanoPi M4V2 with 4GB of LPDDR4. Before installing Armbian, I tried FriendlyElec and the total amount of 4GB of RAM was detected. When moving to Armbian Buster with kernel 5.9.14-rockchip64, the system is detecting only 2GB of RAM (MemTotal: 1964780 kB). I searched the forum to see if anyone else was having this problem but strangely I found no more reports of this issue. I also tried Armbian Focal, but the problem remains. Thank you.

I am thinking to buy NanoPi M4v2 and i want to use with nvme SSD. RockPi 4 support Gen 2.0. What about NanoPi? NanoPi only support Gen1? And what is the maximum theoretical speed for nvme SSD on NanoPi M4v2 ? I am between NanoPi M4v2 vs RockPi 4 and NanoPc T4. I like NanoPi M4 design and box, I don't like rock pi ssd hat and box, and NanoPc price is expensive, not compact like NanoPi, ram is LPDDR3 others LPDDR4, but x4 lane and support Gen 2.1 is good. I am so confused..

My NanoPi M4V2 is currently being used completely headless just to run a few Docker containers (AdGuard Home, Home Assistant, Zigbee2Mqtt, etc.) and I've been noticing more and more crashes happening... sometimes they occur while I have an open SSH terminal, and I get a glimpse of a "kernel panic" type error... Here's the output from armbianconfig: http://ix.io/2vFX Any ideas on what this is or how to fix it? Thanks in advance!

Hi, I'm new to Linux and Armbian, I need your help. My Nanopi M4 V2 freezes periodically and I can’t understand the reason. I am using Armbian Buster with Kernel 5.4.2.

I am attaching the last uboot logs until "start kernel ..." msg Any clue as to why the board is not booting? m4v2_uboot_log.txt

Hi - trust this is the right forum. I have forgotten the login password to my Arbian installation on the nanopi m4 V2. It boots from the eMMC just fine, but I am stuck at the prompt. I had only just installed it a few weeks ago (then things got hectic), so nothing really invested - I could just install again via the SD card, right? Unfortunately, it looks like the SD slot is no longer working. In the last 2-3 days nothing seems to boot from it. Which leaves me with an eMMC module loaded up with an Armbian - I think its bionic, because it does have wifi (buster never worked with wifi). In other 'vanilla' flavours of of l…

Hello, I had a NanoPi M4v2 running 5.10.63 (buster) for a while without issue. Both I2C and SPI were working perfectly fine and the system was stable. Today apt updated the kernel to 5.15.25 and it broke multiple things, the first issue was that the network wasn't working properly, yellow light but not green one / no IP requested from the local DHCP server. The overlays on this system were: overlays=dwc3-0-host i2c7 i2c8 spi-spidev overlays=dwc3-0-host i2c7 i2c8 spi-spidev I connected the eMMC moule to a card reader and removed the overlays one by one and found out that `i2c8` was breaking my boot / network: overl…

I see from photos of the FriendlyElec metal case (without display) for the NanoPi M6 that there appear to be two holes for wifi antennas. Does anyone know if the optional wifi card sold by FriendlyElec comes with antennas? If not, are they a standard size which I can buy somewhere else?

Dear Armbians I have a NanoPi Neo 3 board with 1GB of RAM running in a DC for quite a while now. Because of an SD card failure, I had to make a fresh setup with the actual Bookworm image. This image seems to be quite unstable. Device is going up and down all the time. I am unable to find the problem myself. Maybe someone can take a look and help me to fix my stability issue: Debug output: https://paste.armbian.com/sozozoyahi

I've found a problem with Armbian on the NanoPi Neo 4 with USB 3.0. I have a RAID6 via four USB 3.0 external hard disks (I know, not optimum but it's been working fine for years off an older ARM box using USB 2.0). While the RAID works fine on the USB 2.0 port (established this was true afterward), when connected to the USB 3.0 port, the USB 3.0 hub I'm using disconnects after only a few seconds, disconnecting all the drives (of course). I initially used an unpowered USB 3.0 hub (I forget the manufacturer; I can check). I figured at first, this might be a power issue (even though the external drives are all self-powered). I found a 10-port power…

Hi, I have deployed a NanoPi Neo 4 and for the most part, I'm happy with it, but am having a peculiar problem. I am using the manufacturer-supplied serial console cable and USB adapter (via screen /dev/ttyUSBx 115200). Once the machine is properly booted, if I hit enter, I get a serial console as normal. However, I get garbage from u-boot (and presumably from the kernel boot messages). It looks just as if I have a speed mismatch. I have tried many other speeds (1500000, 230400, 57600, 38400, 19200, 9600) and none of these seem to work. What am I doing wrong? Or is the state of the box right now that u-boot sends garbage …

(Don't know if this is the right place for this, but the Github-Issue link lead me to here, so... here it goes) Like the title states, the checksum of the downloaded Armbian 26.8.0 minimal image for the NanoPi NEO3 and the expected checksum for said image differ. I don't know if this is by accident, but I thought I'd report it before this goes unnoticed.

hi, I am running newest armbian for NEO3. I've noticed that when I issue poweroff command armbian shuts down correctly, but the CPU (with heatsink) remains hot. I left my board for 2 days in poweroff state and it remained 'warm' all the time. Is there something that can be done to put CPU to sleep before shutting down system (or some low power state) ?

Greetings, I have multiple NanoPi NEO3s on the same subnet. When booting with Ubuntu 20.04.6 LTS they use the physical MAC address when posting to DHCP, but ARMbian seems to create a default (fake) MAC address and uses that instead. Judging by the "armbianmonitor -U" output, ARMbian knows about the physical MAC address, it just doesn't use it. The NEO3 board is listed as supported, but there is another posting dated 2020 that still seems to be unresolved. MAC address c2:1f:b3:b0:d2:41 seems to be a generic (fake) address that is being used. Is there a remedy to allow it to use the actual hardware address with this kernel ? -- -- -- brack…

Hi Armbians :) Armbian's discontinued support of the NanoPi Neo3 board, hit me very hard. I have operated multiple of these SBCs with Armbian very stable, in different DCs for a long time. Because of the defunctional kernel under Armbian, I was forced to look around for alternatives and only came across Manjaro, DietPi and Friendlyarm published by FriendlyElec themself. Unfortunately I was not happy with Manjaro and Friendlyarm. Dietpi, on the other hand, seems to be doing quite well till now. And most importantly, it doesn't seem to have the kernel/ reboot problem that affected Armbian. But how can that be if it's based on Armbi…

Hi, I have started to work on a Nanopi Neo3 Plus image (rk3528-based, similar to Nanopi Zero2), announced early March 2026. Created a new .csc file, used the Nanopi Zero2 as a template. Built it with the vendor version. Built it with the vendor kernel., but added the "dt" directory with the rk3528-nanopi-rev02.dts to be "automatically" added to the dts directory and Makefile. The base console version seems to work ok when I generate a bookworm image. As I currently only need u-boot, kernel and dtb's to build my own OS (Volumio, volumio.org), it works for me. Of course, I would like to contribute my work (and support it?), but how do I …

/usr/bin/brcm_patchram_plus/rk3399 hogs 100% CPU until rk3399-bluetooth.service is stopped and disabled. The NanoPi Neo3 does not have bluetooth.

Not the final version. Update(8/24/2018): It's time to deal with NEO4, this picture is not the final version. NEO4 will have PCIe x2 and eMMC connector too, and a MIPI-CSI. But the dual-layer USB connector will share USB 3.0 & USB 2.0, Type-C take another USB 3.0.

I just bought a FriendlyElec NanoPi Neo4 having had loads of experience with Armbian on Allwinner (OrangePi) boards. My preferred method for getting boards "up and running" is simply to connect a serial terminal to the debug port and power on. I tried this with several Armbian Buster images and found that I couldn't log in as root on any of them. Checking the SD card on my laptop, the debug port (ttyFIQ0) was missing from /etc/securetty. Editing /etc/securetty and adding ttyFIQ0 on a new line at the bottom of the file and all is well and I now have Buster up and running on the Neo4 :-) root@nanopineo4:/etc# diff securetty~ s…

Hello, I am working with "Armbian_21.08.1_Nanopineo4_focal_current_5.10.60" on a nanopi Neo4. During the initial boot, the (HDMI) monitor shortly displayed some text (went to fast to read) and then went blank and the monitor turned off. However, output came through the serial debug port (USB2) and I was able to complete the initial setup. Now, I can now connect with SSH, but it would be nice to be able to work directly. How can I redirect the output to the HDMI monitor? Cheers, John

Last FriendlyElec nanopi-r2s image has hardware rng, what about adding it to Armbian? For my nanopi-r2s I patched dtb, compiled kernel module with dkms and managed to make it work with rngd.
