Hi everyone, and sorry for my poor English. I'd like to enable PWM on my CM3588 nanoPC with the latest Armbian Trixie version. Can anyone who's managed to get the PWM working properly tell me which pin to connect the PWM signal to and what exactly to do to enable it? Thanks to anyone who replies.

Thank you Pearo, What does "S/N" mean? I just ended up using my orange pi zero 3 gpio without the additional DTS, which made connector numbering available in the gpioinfo command... There were comments that made it sound not really necessary, and it was more work than I wanted to take on. The solution for me was: https://forum.armbian.com/topic/33800-orange-pi-zero-3-gpio/#findComment-181191 This was 2 years ago, and I haven't even thought about it, all this time.

I really hope that Orange Pi engineers learn to make Armbian patches, enter the community and give funding accordingly

Hallo, in want to start with odroid n2+ to organize a PV System with smart-power-meter(s) ... To reduce th amount of components I want to use min. 2x UART's from the odroid (without using the console port) + RS485 Transceiver(s) ... I understand that your dtbo file add support for the Uart's of the 40 pin Socket ! ? After upgrading to linux kernel-6.18.5 i need such a dtbs / dtb0 file... Where can I download these files atually ? Bye

How best to do that? I've been treating systemd like a rattlesnake which I've seen in record breaking size, 7 feet long and the size of my calf. I was about 6, my stepfather was farming, had come in for lunch, opened the door to go back out and plow, slammed the door, reached over it for a cheap busted shotgun and a shell. reopened the door and took the head off it. 85 years ago. I haven't had a whole lot of use for a rattlesnake since although I've seen hundreds. Blacksnakes OTOH are goodfellows. They keep the rodents away by eating them.

After applying the following two kernel patches which I understand are valid for mainline kernel only, I can use the display properly with a resolution 3440x1440 and refresh rate of 60Hz: patchwork.kernel.org [RFC,v1] drm/meson: venc: add support for HDMI DMT modes up to 3840x2160 -... github.com/chewitt/linux WIP: drm/meson: add support for higher bandwidth DMT modes committed Jan 5, 2026 xdarklight +3 -3 There's a report from a user with a DELL U3415W monitor and a Khadas VIM3 statin… - But having both patches applied or not does not matter, in general with mainline kernel the display is flickering/shaking only during boot, any idea how to get this addressed? thx

I've read that page and I can't seem to get it working with the image both jock and Victor Picinin recommended yet it doesn't boot off the eMMC nor the SD. I'm at the end of my rope!

I have burned the image "Armbian-unofficial_25.05.0-trunk_X96q-ddr3_bookworm_edge_6.12.11_server.img.xz" using Balena Etcher to an SD card, then put it in the box and the light is blue, but the screen is black. please help, thank you this is a photo of the board I used

I have experienced something similar in the past and it made me very puzzled until I figured out what was wrong in that situation. Make sure the clock on both systems are synchronized to an NTP server. IIRC SSH just threw a fit exactly like this without logging why, and it turned out to be a security feature where the ssh server suspected the communication to be intercepted by man-in-the-middle due to clocks not being synchronized. And if logging in physically to the system, apt refused to work as-well until clock was synced. Could be worth to check next time... As for dhcp and systemd. Check if systemd-resolved.service is messing something up for you, maybe try to disable it?

please look herer , maybe some post later and newer Some OPTEE Loader work 1min , one 30min , in the past same game was with trustOS (bootloader) there are two or three diffirrent

Actually not really strange but a measure for spam prevention.

We don't have intention to support this board without funding. However anyone from the community can step up and add support for it.

Hi, does this version of the S805 have HDMI and Wi-Fi? Could you explain more about this backup? Thank you.

I also hope Armbian will support this board, as it offers a very good price-to-performance ratio.

So.... I am the winner of a Inovato Quadra4K from a drawing at my amateur radio club meeting. Yeah! Cool! It runs a software called HamClock automagically.... BUT WAIT! There is MORE! You can exit that app and run other applications... Providing you have a mouse & keyboard (because I am a native WinWeenie) or keyboard if you are a Linux forever personage. It also has a wireless interface that I would like to configure so it doesn't have to have an Ethernet tail tied to a port on our ISP router. I would rather it was mounted to a HDMI TV or monitor. So, I need the keyboard (and because I am a longtime WinWeenie and rodent dependent) mouse to reconfigure it. I would like to have it use a USB Logitech Unifier Nano dongle with wireless keyboard/mouse. By the way, the brilliant man that came up with this computer is trudging the same path I am, fighting cancer. His fight has gotten so tough he has shut down his company. I hope he gets better. Is there already a compiled binary for this with directions,,. or do I have to master the dark arts of programming routines, subroutines, interrupts, memory fetches, writes, threads and all that then compile it into something the machine understands? Please understand I didn't even take typing in high school, so college was a real bear.... When I was in high school Jobs and Wozniak were still dumpster diving behind Xerox-Park Corporation and Radio Shack. Any takers on this one? Thanks in advance, Dave, The-Other-One

> maybe you mean Gbit than 8Gbit = 1GByte Ram Looks ok Oh yes, forgive me, I must've been mistaken! Anywho, mind telling me what I can do about Secureboot or OPTEE you mention?

this looks like we mention many times that OPTEE or Secureboot interrupte the boot at diffirent time you say 128GB and 8 GB , thats not possible with rk3228 it can handle only 1GByte RAM (8Gbits) (maybe you mean Gbit than 8Gbit = 1GByte Ram Looks ok )

@Werner If you have the chance, please check my account too, because I don't know what the problem might be with it, but it's a bit frustrating. Edit: Did this fix itself? After my second post, it immediately became "Members". That's a bit strange...

Hey there forum! I've got this MXQ PRO 5G TV Box (Yes, I know It's been said the brand isn't important, but I figured I might as well say it anyways) thing a few days ago and, as you do, my first instinct was 'Let's linux it', which Is, as It turns out far more trouble than I had initially imagined. And frankly I am a little tired of slamming my head into a brick wall, repeating the same steps again and again so as a sort of last resort, I'm here to ask for your help (thanks in advance). To check which image to download and what steps to follow I've opened the box to take a peek at It's board. As the main CPU, RK3228A, for the storage 128GB of eMMC, and for the memory 8GB of RAM (which exactly type, I can't discover). Following the instructions on the first page of this topic, I downloaded an image, downloaded multitool, got my SD card. At first everything went according to the guide. Multitool flashed, the thing booted It and the partition expanded, then I shut it down and put the extracted .img into the 'images' folder, plug the card back in boot, flash, shut down once more and upon trying to boot, the LED stays off and doesn't turn on. After waiting for a solid 10 minutes I decide I'll just try booting it directly off the card. I flash It, plug it in and some images booted partially and some didn't. Some boot only to a certain point like starting a specific service (usually it got stuck after or during starting armbian-ramlog.service) and some just don't boot at all. I've tried disabling the services by manipulating the files on the card yet they just reappear again. After that I noticed that upon each boot there's a quick 'error' that happens, returning different numbers seemingly depending on the image on the card, either Internal error: Oops: 805 [#1] SMP ARM, or Oops: 80000005 SMP ARM or just Oops 5 which as far as I could find meant something related to illegal instructions (specifically interrupts). I haven't really made any progress past that. Also, If It's of any help, I can provide images of the board (from both sides) and all of It's components. Thanks in advance for all your help, friends!

Hi, I learnt how to customize the image, and also found a simpler way to achieve the bootstrapping alsaloop. Here is the forked repository and a pre-built image for you to try. Supposedly, you just need to flash the image, and it should work out of the box. As the radxa zero 3w does not have the Ethernet port, so you will not accenditally connect it to some networking, I think it is fine to leave the root password as the default. However, if you plan to connect the device to some networking, remember to set up the root password. The Wifi is also working with the latest kernel release (my wifi module is broken, but I do see dmesg is trying to interact with that module).

Hi, how are you? Well, I don't know English very well, so this text will be translated using Google Translate since I'm Brazilian. Anyway. I found a way to boot the SD card with Linux on the Allwinner H3 chip, using a Chinese MXQ 4K 5G TV box. I booted Android normally and, using the remote control, pressed the power button and then confirmed. After shutting down, I booted with the remote control and Linux started normally. After that, every time I booted with the SD card, it booted perfectly. Another thing I did before, but I believe it doesn't affect this, was to enable USB0 device mode in developer mode. I hope this information helps with your Linux projects!

I really hope that Armbian will be released soon for this board. I have it, but the official ISO has an old kernel and no RT capability.

your sbc has only 100mbit nic

Hi. My download speed is so low over ethernet. Speed must be 19Mb/sec, but real speed is 7-8Mb/sec. download speed on armbian download speed without armbian Tell me what is my problem?

The puzzle seems to have resolved itself. I gave up and shut the printer off about 04:00 this morning and went to bed. Got back up, powered it on about 08:30, and its all working, updating 304 pkgs right now. It was rebooted at least 15 times as I worked last night w/o any affect. What the hell is the diff between a reboot and a full powerdown of 4+ hours??? Did dd-wrt flush its cache of MAC addresses? IDK. But w/o a global net, I was trapped, I could not DL the tools needed to troubleshoot. A very frustrating state of affairs. I do not see anyplace where I could mark this as solved.
