Hello, I have been experimenting with the bluetooth audio on my tinkerboard. The issue is both present on the last rockchip-next (4.1x I think) and the rockchip-current 5.8.18 kernel. I am using bluez and bluealsa. The problem is specific to the onboard bluetooth, using an external bluetooth dongle (a cheap and old CSR Bluetooth 3.0 dongle from China) works as expected, I can even send audio to multiple devices simultaneously (quality is very bad, but thats a bandwidth problem). As long as I just connect one bluetooth audio device everything is fine. I can have multiple paired, but disconnected, devices and as long as I connect and play and diconnect, things keep working. But as soon as I try to connect a second device, while another one is already connected (not even playing), the second device shortly shows up as connected in `bluetoothctl` (while the LED on the speaker itself stil shows not-connected) and about 10-20 seconds later the device shows up as disconnected and would not even reconnect unless switched on or off. The error logged by bluetoothd / bluez (5.55-1) is bluetoothd[15142]: profiles/audio/avdtp.c:avdtp_connect_cb() connect to 74:A3:xx:xx:xx:xx: Connection refused (111) The connection process does not reach the bluealsa layer, I had similar problems when quickly testing with pulseaudio's bluetooth module. My question: Is there anywhere in the armbian tinkerboard configuration some hardcoded option to only connect to one device at a time? I cannot imagine this to be alimit of the on-board chip, Are there any config options for the HCI UART kernel driver?

Hi. I would like to download last armbian image for my Asus tinkerboard, but all download links broken: https://www.armbian.com/tinkerboard/ Can you fix that? I found Armbian_20.08.1_Tinkerboard_focal_current_5.8.6_desktop.img.xz here: https://armbian.tnahosting.net/archive/tinkerboard/archive/ Is that latest one?

Hi, since i have a Asus tinkerboard incoming i was wondering if anyone knows if the "generic" arm64 distro will work this board. Its based of the rockchip RK3288 SoC The support pages states that the board supports debian, but since i dont need a UI ect (im going to use it headless) i dont need the board to load a ui into memory and wanted to use a normal build instead of the TinkerOS Please note, my knowledge of the inner workings of *nix is quite limited, so if my question is to generic or imprecise i apologize.

Just as a notice the Raspberrry PI 7" DSI Touchscreen was working fine on Armbian with the 4.4 Kernel. Using the current Armbian for Tinkerboard and the 4.19 Kernel it does not work any longer, nor does it with the current development Kernel 5.1. Does there have to be any special things to be set to get it working again? On the 4.4 Kernel it was working out of the box. Thanx

I am testing RK3288 with ubuntu 20.04 (gnome) btw NICE And I have some problems with panfrost and I am looking for anybody with RK3288 device that can confirm or not same behavior. Problem is that when I switch GPU to 600MHz sudo bash -c 'echo "userspace" > /sys/class/drm/card1/device/devfreq/ffa30000.gpu/governor' sudo bash -c 'echo "600000000" > /sys/class/drm/card1/device/devfreq/ffa30000.gpu/userspace/set_freq' and when I run glmark2-es2 or glmark2-es2-wayland I start to see https://pastebin.com/NuYqHdxH in kernel.log So I made bugreport(https://gitlab.freedesktop.org/mesa/mesa/-/issues/2693) for panfrost and they think that problem is in low voltage on gpu as everything is fine on 400MHz So anybody can try? just build ubuntu 20.04 for your RK3288 device sudo BETA=yes EXPERT=yes ./compile.sh server build should be fine and then apt install ubuntu-desktop ubuntu 20.04 has almost latest mesa so everything work just fine

In order to review the Tinker Board boot logs via serial console, I set up armbianEnv.txt to get the logs. But Armbian didn't output anything. Can anyone tell me what is wrong? As long as I reviewed boot.cmd, the serial port was assigned to /dev/ttyS2. So I used UART2 GPIO pins (GP7C7 for TX, GP7C6 for RX) to interact. (snip) if test "${console}" = "serial" || test "${console}" = "both"; then setenv consoleargs "console=ttyS2,115200n8 ${consoleargs}"; fi (snip) The barudrate is 115200. Of course, I re-checked my connection between USB-UART serial cable and UART2 GPIO pins (USB-UART RX to GP7C7TX, USB-UART TX to GP7C6 RX). Any information is helpful and appreciated. Thanks. ---- Referenced Doc: https://docs.armbian.com/User-Guide_Allwinner_overlays/#example-bootarmbianenvtxt-contents my armbianEnv.txt: I added console=serial. verbosity=1 console=serial overlay_prefix=rockchip overlays=i2c1 i2c4 spi2 spidev2 uart1 uart2 rootdev=UUID=(stripped) rootfstype=ext4 usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u USB UART Cable: FTDI TTL-232R-3V3 Board Product: ASUS Tinker Board (Power supply via GPIO, 5V4A) Armbian Image File: Armbian_20.05.2_Tinkerboard_buster_current_5.4.44_minimal.img.xz OS Info: root@tinkerboard:/boot# cat /etc/armbian-release # PLEASE DO NOT EDIT THIS FILE BOARD=tinkerboard BOARD_NAME="Tinkerboard" BOARDFAMILY=rockchip BUILD_REPOSITORY_URL=https://github.com/armbian/build BUILD_REPOSITORY_COMMIT=2efd215a DISTRIBUTION_CODENAME=buster DISTRIBUTION_STATUS=supported VERSION=20.05.2 LINUXFAMILY=rockchip BRANCH=current ARCH=arm IMAGE_TYPE=stable BOARD_TYPE=conf INITRD_ARCH=arm KERNEL_IMAGE_TYPE=Image root@tinkerboard:/boot# uname -a Linux tinkerboard 5.4.44-rockchip #20.05.2 SMP PREEMPT Wed Jun 3 10:43:15 CEST 2020 armv7l GNU/Linux

Hello people, I use a Tinker Board as a low power desktop computer for browsing, office documents and general tinkering, and after all this time it got personalized enough to worry about loosing all this setup and it is a hassle to just overwrite everything every time a new image comes around. Was wondering if it is possible to use apt dist-upgrade as means to get from Bionic Desktop 5.4 to Focal Desktop 5.4 as can be done on x86 platforms without breaking everything?

I logged an issue a little while ago with Armbian running on the Tinkerboard that the screen when rotated 90 degrees couldn't draw the screen at any speed. I have been playing with a few alternatives incl going back to the original tinkeros. All have issues so I was delighted to see the FOCAL port. I am using the recommended Waveshare 7" touchscreen that you advertise on the home page as tested 3rd party hardware. Both the desktop and the server versions of Focal come up with the error Configure crtc 0 failed setting mode when I manually set the supported resolution of 1024 x 600 at 60Hz using xrandr Exactly the same settings on TinkerOS works perfectly., but has many other issues! In the /var/log/Xorg.0.log file there is an message Allocate new frame buffer 1024 x 600 stride failed to set mode : Invalid argument. I used cvt to generate the modeline using settings 1024 600 60 then I used xrandr --newmode and added the modeline xrandr --addmode HDMI-1 1024x600_60.00 When I set the output to use this setting xrandr --output HDMI-1 --mode "1024x600_60.00" I get the error crtc 0 failed. As mentioned this works on TinkerOS and is the device that is included in the tested 3rd party hardware. What I am doing wrong? Thanks in advance.

Hello people, I have an Asus Tinker Board S and decided to use the Mainline Armbian for this board, love the new panfrost driver but seems it is glitching all over the place, icons in the menu disappear and reappear when mouse hovers over them, tick boxes do not show if they are ticked and only flicker when mouse is over them and applications menu keep redrawing all over when trying to use among the most prominent problems. Other operating systems work well in this matter. Anyone else is having these problems with the mainline 5.4.28 kernel build?

However, Armbian is configured to provide only spidev2.0, while TinkerOS can have spidev0.0, spidev0.1, spidev2.0 and spidev2.1 all enabled at the same time as long as you disable UART4 which shares GPIO header pins with SPI0. In the TinkerOS case, there is a config tool which edits a small and straightforward text file in /boot/ containing lines such as "intf:spi0=on" or "intf:uart4=off". The corresponding Armbian file seems to be /boot/armbianEnv.txt - possibly with overlays=... lines and DTS files. There also is a tool called armbian-add-overlay to load (at runtime?) DTS files...

So recently I decided to use my (quite old) tinker board, I downloaded the last armbian (desktop, 4.4.213) OS, managed to install a vncserver (x11vnc) and also to use it without a screen plugged in it. And now I would like to turn it into a urbackup server, but I got some error with mdadm, "Module md_mod not found in directory /lib/modules/4.4.213-rockchip". I tried to use this forum to find a solution (https://github.com/armbian/build), but I couldn't make it work. When i tipe ´´git clone https://github.com/armbian/build´´ it stop around 7% at resolving deltas, and it just freeze. Someone could have any idea how to solve this issue?? And i can't get my armbianmonitor link to paste...... Thanks guys.

If anyone has troubles with HDMI when using 5.x kernels, and has enough skills to recompile an armbian, give this a try : https://github.com/Miouyouyou/build And then either answer here, or in the bug report : https://github.com/armbian/build/pull/1887

So I have armbian installed on a tinkerboard and have had absolutely no issues with it until I bought a new Samsung 7000 series TV (2019). For some reason this TV does not recognize the signal coming from the tinkerboard. For the life of me I cannot figure out how to get this to work. I notice a few references online about being able to force a resolution but nothing related to the rockchip boards. Is there an equivalent way to force a display resolution as in this article? https://docs.armbian.com/Hardware_Allwinner/#how-to-reconfigure-video-output I'm running 4.19.21-rockchip 5.76 I've also tried kernel 5.4.28 as well and it's the same issue. Just for kicks I loaded Lakka on there and it works just fine so I know the board itself is working properly. I don't even know where to begin. I was hoping someone could chime in and point me in the right direction.

Hi, I installed "Armbian_20.02.7_Tinkerboard_buster_current_5.4.28_minimal" at my tinkerboard and, in order to enable uart 4, I had to rebuild the kernel onboard (from linux-source-current-rockchip_20.02.7_all.deb). The uart 4 came alive but the processor serial number now is missing from cpuinfo (printing 0000000000). How can I bring it up again?

Topic to discuss RK3288 overlays, primarily concerning ASUS Tinker Board, the MiQi is technically EOL and has very little GPIO anyway, and TV boxes are more or less sealed. Kernel 4.19 will be the pilot for this, the discussion now that it seems to be working thanks to @martinayotte and @zador.blood.stained's feedback and examples is what to overlay. For testing/debugging I started with some ASUS overlays for RTC and 1wire. Easy ones: spidev out of the default tree but as default overlays. instead of making 1 overlay and messing with parameters, just make 2 overlays DAC's: I don't have a lot of hardware to play with, but @gkkpch has contributed to the existing ASUS overlays, if we ask super nicely maybe we'll get some help. I2S on mainline is a question Harder ones: RPI display: I almost got this working on Mainline, I need to return to it, make it work, and make it an overlay. Cameras: I honestly don't know if this is actually possible, I need to look at the drivers a bit more closely. Original Content from Split:

Hi. I installed Armbian_20.02.1_Tinkerboard_bionic_current_5.4.20_desktop on my TinkerBoard (not S) and get weird screen state (white, then growing black circle in the middle). I tried Armbian_20.02.1_Tinkerboard_bionic_legacy_4.4.213_desktop and it works very good, but I still want to test vulkan driver, so I updated only kernel to 4.19 (install linux-image-next-rockchip, linux-header-next-rockchip, linux-dtb-next-rockchip and delete 3 old packages). After reboot I got same screen. Is it known bug? Can it be related, that I'm using HDMI-to-VGA adapter? Can you help me to fix it or get usefull logs?

I have a TinkerBoard S. In Bionic Desktop (kernel 4.4), the wireless icon menu lists two devices: wlan0 (which is the expected interface) and p2p0: I don't know this one, but it is always chosen for auto-connecting to the local wireless lan, receiving a random IP and not the one I configured on the router. I can then manually connect to the network with the wlan0 interface the IP is correct. How do I disable / remove / anyway stop that p2p0 interface to "steal" the network connection?

I used sudo swapoff -a as suggested in this thread: but the setting isn't persisted, and upon reboot sudo swapon --summary shows a partition There's no "swap" text in my /etc/fstab I'm trying to install Kubernetes, so I need to disable swap.

Hello, I own a Tinker Board S (bought one or two years ago) attached to a Sony Bravia KDL 22EX320 TV by HDMI, which has a native resolution of 1388x768 pixels. Bionic desktop with kernel 5.4 (got from https://dl.armbian.com/tinkerboard/Bionic_current_desktop) didn't properly recognize the TV resolution, but set it to 1920x1024. If I run xrandr --props the resolution is not listed. I'm posting because I'm almost sure that the old TinkerOS 2.0.8 (that I installed with the board) recognized the TV resolution correctly - it anyway boots to desktop without requiring interaction, so not being able to read the text at the edges of the console is not a big issue - and I just tested that the current 2.1.11 does too: they both start in 1920x1024, but the Monitor settings windows lists 1360x768. Back to Armbian, I however managed to create the default user and to get to the Bionic desktop; I'd like to add that the display settings window should have a "Test" function that reverts to the previous settings if the new aren't confirmed, because if the chosen resolution isn't supported, the screen stays black.

I have Tinker Board S. I have been using both Tinker OS and Armbian for a while. Recently I upgraded to 5.4.28-rockchip. I noticed that randomly and frequently when I watch cnn.com or other media, my video would freeze. Initially I thought the firefox or chromium crashes. However, later, I realized it was the network issue. Other devices were still able to connect to the internet. When I checked the ifconfig, the network devices still showed proper connection. However, there is no way to ping any URLs. Disconnecting/reconnecting network does not fix the issue. The only fix was reboot. How can I troubleshoot this issue? I was trying to do armbianmonitor but at that time, there was no network at all. http://ix.io/2fVR This is armbianmonitor after reboot and no problem at all. for baseline reference.

Hello togehter, i had 2 ASUS TinkerBoard S and I want to work with your software... The Software was via Etcher installed on several MC - Cards (16, 32 and 64 GB), but it still not working. The POWER - LED is red and the both LEDs on GBIC - Interface are blinking green and yellow :-( So, what kind of problems that I have here. I tried out several IMAGE from your WebSite - but no one won't to work with me :-( Best regards Matthias

Using Linux tinkerboard 4.19.69-rockchip #5.95 SMP PREEMPT Mon Sep 2 07:34:36 CEST 2019 armv7l armv7l armv7l GNU/Linux Using glxgears as a test case.. I get 60fps without the screen rotated. If I rotate the screen right or left the frame rate drops to 4fps. That's on a fresh boot with nothing else running. I tested TinkerOS on the same board and it works fine rotated. My Raspberry PI 4 works fine rotated as well. What could be the problem with Armbian?

Anyone have an issue where on a fresh install with apt update and upgrade I create a hotspot then have openvpn connect on boot. It works fine as a hotspot with 200mbps up and down but when the traffic is routes through a vpn by connecting openvpn the board will crash/become unresponsive if the upload is used heavily. Works great until I run a speedtest and on the upload the board will crash. Normal use is fine even pegging download causes no issue. Le potato s905x works amazing in this regard and never crashes period. Is this a known bug?
