Hi, I was testing images for Orange Pi 4 w/o eMMC, official from site, Debian and Ubuntu from ARMbian, and suddenly any boots anymore. I tried desperately everything, write with another program, used dd for copy, pressed randomly bottoms attached in the back, then one time worked, but it crashed when i attached a keyboard. Later all my micro-sd cards worked, most of them are poor quality, could be that but idk, my power adapter came from official website. # ls usb doesn't show hid I have a cp2012 usb to tll, i can use it for serial debug ?

When is it likely to get support and Armbian image for Orangi Pi 4B? Thanks Rajesh

As topics title, did anyone manage to get the Raspberry Pi Touch Screen (DSI) work with the Rock Pi 4B running Armbian? Should it be working out of the box like with the TinkerBoard? Note that in my setup the display works with the Radxa Debian 9 image. Thanks guys

Hi, I'm a user of nanoPC T4( RK3399), now i'm using offical ubuntu release. did Armbian for nanoPC T4 support it's MIPI dual camera? ISP? and other media function? thank you!

hello everyone I have this board orange pi 4 V 1.3 Armbian Focal desktop mainline based kernel 5.4.y . I haven't audio through HDMI. what can I do ? I ran the media script for hw acceleration and i have good video result but not audio. Thx!

Hey guys, bunch of thanks for your great work. Was wondering what's up with the latest buster images (20.05.2-5.4.43) for the 1Gig A versions. Worked great up to 20.02.11-5.4.32.

This overlays settings worked well until I have compiled my own .dtbo file and call it with overlay=..xyz... , after that all yet working overlays stopped working, even if I removed them. The boot process now skips this overlay settings. After examination, I have found file "/boot/boot.scr" and "/boot/dtb-5.4.44-rockchip64/rockchip/overlay/rockchip-fixup.scr" had some garbage characters at beginning. I didn't change anything, neither I did open them before, those files simply got garbage. After deleting the garbage chars, it won't boot anymore. Before I had tried also spi-spidev and spi-nor

I'm working on a project using the nanopim4v2-current image. I noticed an issue with the available HDMI output resolutions. Only a select few resolutions are available, despite the connected screen advertising support for additional ones. I was also unable to output a custom resolution (for example 1920x538) by adding the proper modeline in manually through xrandr. I've been looking into this for a bit and managed to find a partial solution in Miouyouyou's recent pull request "[RFC] RK3288 : Add HDMI resolutions". Adding the patches to my build enabled support for my monitor's native resolution (1920x1200) and allowed me the ability to output custom resol…

EDIT: I hate to have to admit this, but I completely forgot that the nanopi m4 v2 needs external antennas for its wifi to operate properly. (I bought just before the coronavirus hit, and it was several weeks before I got back to setting up the board. First board I've had that needs that.)

Hi, I don't have an idea why it stucks. Armbian_20.05.0-trunk_Rockpi-4b_buster_current_5.4.43 EDIT: I have downloaded the pre-build image Armbian_20.05.1_Rockpi-4b_buster_current_5.4.43 and it works. It boots at an astonishing speed, only 18 sec which is a miracle. How can I build the same kernel? Is sufficient to copy just a .config file?

Hi everyone, I have been playing a lot (too much maybe) with my NanoPi M4. It seems that most of what I need will be working "soon" (yay for hardware decoding), except HDMI audio bitstream passthrough. Whatever kernel I try, I always get this output from Kodi: Device 1 m_deviceName : default m_displayName : Default (hdmi-sound ff8a0000.i2s-i2s-hifi i2s-hifi-0) () m_displayNameExtra: m_deviceType : AE_DEVTYPE_PCM m_channels : FL, FR, LFE, UNKNOWN1, FC, BC, BL, BR, BLOC, BROC, FLOC, FROC m_sampleRates : 32000,44100,48000,88200,96000,176400,192000 m_d…

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…

Hi all, first off, I love my NanoPiM4V2 boards, the big drawback with them for me is backing them up, if you are running them from an eMMC and you have the board in a case, you have to remove the cover of the case, if you have a hat ( which I do ) you also have to remove that , then you can remove the eMMC module and clone or do whatever with it. What would be good for me, is, if I could temporarily boot from an sdcard , unmount the eMMC, and clone it for backup purposes. Before I ruin anything I thought I'd ask the experts. Is this doable ?

Hello all, After some time without touching it, I came back to my Rockpi 4B. I installed the latest armbian bionic image on a samsung 64Go card. All seems to work fine for the first boot. But when I try to restart the system I don't get any display on screen. To get it back I need to unplug HDMI plug and re-plug it. Didn't found any conversation about that trouble? Is it a bug or is there something I can do to fix it ? Thanks for your answers. Pat

Hello all, I have this board and It's suffering crashes and reboots all day. I think the logs are stored in RAM because I can't never find anything related to this issue. Is there anything I can do to find the cause? Many thanks. Regards.

I'm not sure what I'm doing wrong, I'm not an expert with this. I have the M4V2 with metal case. I downloaded Armbian_20.02.7_Nanopim4v2_bionic_legacy_4.4.213_desktop.7z and burned the IMG to one of my spare M4 eMMc Problem is that the eMMC does not boot and does nothing So I tried another M4 eMMC and exactly the same thing. So I burned the img to an SD card and it boots fine. But I cannot see the eMMC AT ALL, lsblk does not show it Is it possible the M4 eMMC is NOT compatible ( I dont' think so or I would have seen in my searches) OR I did something wrong ? Or missed a step I don't remember having this with my M4 ? Thanks in …

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.

Hi all, currently i'm working on upcoming Helios64 board. For RK3399 board there are 2 families, what are the differences between them? I've been following discussion on github and this forum for few months but still unsure which family i should use.

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?

Hi, I have one FriendlyARM NanoPi R2S. It should have 1G DDR4 memory. Everything works fine with latest Armbian 20.02.08 except only 512M memory shows up.

Hi, I have one silly problem developing a FBTFT device driver for SSD1322 display : https://github.com/MarkoBursic/fbtft---SSD1322/blob/master/fb_ssd1322.c The initialisation starts OK, all GPIOs (DC, RESET, CS) follows as they should, since the data is sent through a function write_reg. For example : write_reg(par, 0xA0, 0x14, 0x11); It asserts DC low, then sends 0xA0, then asserts DC high and sends 0x14 and 0x11. Within every sent character (8bit bata) the CS toggles. The problem becomes when I want to send video data, I guess a function write_vmem is called. But here the entire tx buffer is filled and then streamed. for (y =…

After the next (last) update, the system does not boot, there is no ssh access, and the monitor does not turn on. I just didn't install updates for three weeks and decided to update yesterday What should I do, re-install the system ? The loader is located on the sd card, and the system is on the hdd, using the 4.4.x kernel

I want to use the mainline u-boot spl to load the u-boot proper(u-boot.itb) from nvme, so that the only part off the nvme is the tpl/spl in the emmc/sd/spi flash. But now the mainline u-boot has no pcie driver and no nvme support in spl. I have found the radxa guys using their u-boot in spi flash to boot kernel from nvme. But their pcie driver(https://github.com/radxa/u-boot/commit/096f2c16bbfa24c93a4c87e31334d5b5064dfd0a) has a limitation: It can not be used in u-boot spl, or it would not function properly in u-boot proper and fail the boot. After some frustrating tryings and compare with the linux driver, I found that the port initialization proce…

Hi! Unless mistaken, I believe audio is missing from 3.5mm jack on the RockPi4b. To enable it, I had: - To update the dts by adding definitions close to the RockPro64 (some available starting in mainline 5.6) - Change them to use I2S0 instead of I2S1 - Enable audio-graph-card in kernel config (I also removed some audio modules which issued warnings/errors during boot) - Patch es8316.c to prevent a kernel panic during boot (found in Ayufan's latest mainline kernel for RockPro64) yannick@rockpi-4b:~$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: rockchiprk3399 [rockchip,rk3399], device 0: ff880000.i2s-ES8316 HiFi ES8…

Hi. Every few days I've been noticing that my monitor just goes blank. The machine keeps running but nothing I do will restore the display. Even if I try to visit another virtual terminal, nothing, still blank. I can ssh to the machine but no command will allow me to restore the display. The only way I get the display back is to reboot the machine. This can't be normal. I'd love it for someone to help get to the heart of this problem. Thank you.

Hi, I have a problem with my NanoPi M4V2 (with Raspberry Pi 4 power supply) and the new Armbian release 19.11.3 (Buster). I can boot the image from SD, eMMC.

Hi all, I have been using a Rock64 with hostapd and a usb adapter that uses realtek drivers for a couple of months now. Recently, like a week or two, after what i believe was a kernel update i started getting random freezes in the board. As i use it "headless", when it happens the only way to get it back working is by power cycling it. This means that until today i had no logs of what was happening. Today although, i left my laptop on for a couple hours, with tail -f on kernel.log, messages and syslog. Attached in the file called logs.txt is what i managed to obtain from a terminated ssh session to the board. Im running Linux NetMa…

I'm trying to run Armbian on Orange Pi RK3399 board. I have TP50265 permanently shorted to the ground to enable SD card booting.

Good morning gentlemen, I have just discovered that one of the cores on my RockPi4B is faulty and often causes segfaults and crashes, I can disable the suspect core by issuing the following command $ sudo echo 0 | sudo tee /sys/devices/system/cpu/cpu2/online However, this is fine if the machine has booted, but i want to disable the faulty core as early on in the boot process as possible. Is it possible to disable the core in the uboot environment, or could someone offer me some advice as to the best time to disable the core? Thanks, Leon.

Greetings, Here's a quick and very dirty way to use the NVMe disk for the whole system, except the boot files and kernels which will be read from the SDCard. This method is UNSUPPORTED. Meaning that if you follow this procedure and your system broke, catched fire and start attacking you in your sleep, it's on you ! The reason I keep booting on the SDCard are : This makes boot issues easier to deal with since all the files are more easily accessible. It's easy to quickly read a SDCard from a PC using a SDCard reader USB dongle bought from the local store. Meanwhile mounting a NVMe<->USB readers are no…

Hi, i'm new to armbian and i hope to write in the right place I have a rock64 and deployed it as a remote server. Since it is in a shared place, to better protect my and my user's privacy i enabled Full Disk Encryption (CRYPTROOT_ENABLE). Now, back to the question: is usb otg enabled by default? Can someone with physical access use an otg cable to read files from the rock64? I would try it by myself but i don't have physical access to the board.

I'm about to install active cooling fan on my recently delivered nanoPI T4. However, I cannot get what is a type of the soldered 3-pin fan connector on this board?

I have a Rock Pi4 B (rk3399) and I do not find the solution to use my native screen resolution with the latest kernel: 1600x1200. It was working fine with Armbian Bionic Legacy kernel 4.4.

Flashed Armbian Buster to eMMc and now want to flash to Armbian Bionic. I know there's instructions using a usbC in the friendlyarm wiki but this just isn't working out... I used the Windows method / tool to erase the eMMC as it says which seemed to work but it still boots from the eMMC :/ Are there any better instructions any where?

WIthout SD card, it boots normally, but if SD card is inserted, it won’t boot. On serial port, it is visible that there’s a crash right after the message that says something like “booting from eMMC”. The message includes the values of the registers IIRC. Then, something like “resetting CPU”, and it starts over: tries to boot from eMMC, crashes, etc. Sorry, I didn’t record the exact message, but there’s a chance I’ll re-flash the board in the next couple weeks and then I can provide the exact messages. I’ve tested it with Bionic minimal with 5.4 kernel and buster server with 5.4 kernel. If I insert the SD card later, it’s fine. Also, the official ubuntu bionic …

Hello everyone! I have an issue with rebooting my orangepi 4 (version without eMMC, booted from SD card). May be you can help with some kind of patch or workaround, or may it be a note for armbian devs. System: Debian GNU/Linux 10 (buster) Image: Armbian_20.05.0-trunk_Orangepi4_buster Affected kernel versions: dev-5.5.2; dev-5.5.5, current-5.4.21, legacy-4.4.213 I have built different armbian images from trunk (legacy,current,dev), and it looks like everything works absolutely fine, except the reboot. When I type 'reboot' the last thing I see in the serial log is something like this: [ OK ] Stopped target Local File Syste…

I have noticed that the NanoPi M4V2 has an OPP table which causes the device to overclock; the table is suitable for an RK3399K SoC, but the M4V2 has a standard RK3399 SoC with maximum speeds of 1.42GHz for the A53 cores and 1.80GHz for the A72 cores (despite FriendlyArm themselves citing the K speeds in marketing material, which is incorrect). I believe that this may also be causing stability issues with my unit, however I will be performing additional testing (I cannot find where it is getting the "extended" OPP tables from, so I am limiting it via cpufreq-set and testing for stability.) Does anyone have any insight or ideas?

Hi All, thanks for this great project, much appreciated! Could someone give me an educated guess whether there is a risk of damaging my board when the blue LED is flashing much faster (at least twice, probably more) than usual? I suspect something is changing the frequency or voltage and I'm not sure how much time I can take in this state to try to analyze the problem further. For now I unplug the power when it happens.

Hello, I'm trying to use a NanoPi M4 with an old TV. When the system boots, the TV displays "Invalid resolution." However, it works with a different TV, which unfortunately I cannot use full time. I note that on the working TV, there's a line in dmesg stating "Console: switching to colour frame buffer device 240x67" which would imply that this can be configured somewhere?? However I tried searching, the only docs I get are outdated, for other hardware, or don't work. I tried adding 'disp.screen0_output_mode=1280x720p60' to /boot/armbianEnv.txt, but it had no effect. A pointer as to where these settings are actually controlled would be very helpful. Thanks

Hello, can someone help me with my problem. I have a ROCK64 with 4GB of RAM and an ARMBIAN 5.75 stable Ubuntu 18.04.2 LTS 4.4.174-rockchip64, installed. My issue come with usb ports, from the three USB of the this device only works two: one 2.0 and 3.0. And when i have a disk connected towards usb 3.0 i have issues with port usb 2.0, it doesn't work well and I end up disconnecting the USB 3.0 to can work with my device connected towards USB 2.0 so I assume that the current power on the USB port is having issues or it's not working well. Anybody an idea? thanks!

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

I have a suggestion for the moderators: Please move the Rockchip 3399 subforum from development to Bug Tracker if its ok! Most of the boards listed there: Nanopi Neo4, M4, NanoPC T4, Rock64PRO, Rock Pi4 are now marked as supported on the Armbian download page. I read a comment from @Igor sometime ago (not able to locate right now) that the only thing holding back the sub forum transfer was a lack of moderator action. Thanks.

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.

I saw the official document of NEO4 that FriendlyDesktop had full hardware acceleration support, including video decoder, opengl, built-in Chromium browser, etc. So does this ARMBIAN NEO4 have the same complete hardware acceleration support?

Hi, in Germany electrical Power ist getting more and more expensive (reaching 30ct per kWh).

And I also tried out the Jetson Nano, Ubuntu 18.04. On both Systems you can get a satifsfying Desktop Experience, but the Jetson with ist Cortex A57 Core Base is a bit slower, also while it is used from an micro SD SanDisk A1 Card. For a long time I ve been watching t…

Hi. I'm using an OrangePi RK3399 and if the power supply from the 12V barrel jack is removed, the LTE module connected to the mPCIE port dies. Does anybody know how to make the mPCIE port work while on battery? The mPCIE dying is due to the port being powered from the main power supply line VBUS from the barrel jack (before the BQ25700a battery charger IC, according to the board's schematics). I don't know why power is not supplied from VSYS like everything else on the board. So, what I've found is that if I want to power the mPCIE port from the battery, the reverse OTG mode from the BQ25700a battery charger IC would need to be set (allowing voltage to flow from the bat…

I am still trying unsuccessfully to get the sound through the rt5651 codec using the main line kernel (I use NanoPC-T4). I corrected the dts/dtb file and assembled the kernel module. The kernel performs i2s bus and codec switching. The corresponding audio device appears on the system. I start a alsamixer. I can change settings. When I change some settings, I can even hear clicks in the dynamic. So the codec chip is powered up. And the codec chip is controlled through the i2c bus. I can switch the audio output through the codec. But there is no sound. I can 't figure out what the reason is. The dts/dtb files for main line kernel and rockchip 4.4.xxx kernel are slightly dif…

Hi guys, I recently bought a Rock PI 4 and installed Armbian Buster with kernel 5.4.6. The os is booting fine but I am facing major performance issues when trying to download from the internet.

The strangest thing happened today. I switched of my rok64 rev.2 and connected to my PC to move the files of my USB HDD. My plan was to change the disk format from NTFS to EXT4. Then when i plugged it back in the rock64 wouldn't boot properly. Turns out my USB 3 port isn't working anymore with the USB HDD or any other USB drive. The light comes on for my SSD but fdisk -l doesn't see it. Could one of the firmware updates broken it? UPDATE... I downloaded the latest Ayufun arm64 bionic build and booted from this. My USB 3 HDD was picked up fine. I've gone back to the new Armbian Bionic build and it doesn't wo…

Hey folks, I ordered an Orange Pi 4 a couple weeks ago, and it showed up on Wednesday. Last night I started tinkering around with to see if I could get Armbian up and running on it. First thing I did was to hook up my USB-to-TTL debugger to it (no SD card inserted). But when I powered it on, all I'm getting over the serial connection is garbage. With my other OPi's, I'm used to getting U-Boot messages -- but this was far from that: The garbage settles down after about 30 seconds. When I have it hooked up to my Windows machine, I get a new device called "rk3399-mid" that appears in device manager. I tried grabbing the i…

Hello All, I recently bought Orange Pi RK3399 and had some problems with it. At this moment I've solved most of them, but still no luck with such an old OS like Ubuntu Server 16.04 or Debian 9 which were provided by the manufacturer (images to flash). What I am thinking now is to move this board to Armbian. Will it work? How should I in this case organize the partitions on eMMC and where to load kernel and rootfs? I don't see this board in supported ones.
