hello @WorapolBuraphan, TinkerBoard2/kernel (github.com) are the source codes of tinker os, which is debian based. the kernel compile process is pretty common and standard. have you faced any difficulties in terms of compiling?

hello @CommandLine726, sorry for the very late reply. unfortunaly if you're using a dsi panel there's no way to rotate the screen; however if you're using a hdmi monitor, you cand rotate the screen by editing the /etc/X11/xorg.conf.d/20-modesetting.conf 1. sudo su 2. cat /etc/X11/xorg.conf.d/20-modesetting.conf (if the configuration exisits, you will see the last section: Section "Monitor" Identifier "Default Monitor" Option "Rotate" "normal") 3. vim /etc/X11/xorg.conf.d/20-modesetting.conf change the Option "Rotate" "normal" to "inverted" "normal" 4. reboot now

hello @Justus, here are the windows drivers that i installed before flashing, please give it a try: https://www.asuswebstorage.com/navigate/a/#/s/9A9AE0E3C26F478CBD0DCE44A26226E54

hello @CubanAzcuy, 1. does it crash only when you connect it to the macbook? 2. were the other usb ports plugged to other peripherals when the issue occurred? 3. what is the power supply you're using?

hello @Fuchsy, x11vnc is giving me some on-and-off disconnections that can be fixed by reconnecting (not perfect, but does the job) i have used teamviewer and anydesk very briefly. what is your setup? tinker board r2.0 as vnc server, it connect to a hdmi monitor and a waveshare lcd panel, and a laptop as vnc client?

This message shows that your installation appears to be working correctly. To generate this message, Docker took the following steps: 1. The Docker client contacted the Docker daemon. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub. (arm32v7) 3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal. To try something more ambitious, you can run an Ubuntu container with: $ docker run -it ubuntu bash Share images, automate workflows, and more with a free Docker ID: https://hub.docker.com/ For more examples and ideas, visit: https://docs.docker.com/get-started/ sudo docker info Client: Context: default Debug Mode: false Plugins: buildx: Docker Buildx (Docker Inc.)

hello @Fuchsy, it sounds more like a vnc issue than a waveshare lcd panel issue to me. i've tried to reproduce it with x11vnc v.0.9.13, tinker board os: debian 10 v.2.0.14 x11vnc config: [Unit] Description=Start x11vnc at startup. Requires=display-manager.service After=syslog.target network-online.target Wants=syslog.target network-online.target [Service] Type=simple ExecStart=/usr/bin/x11vnc -display :0 -forever -loop -noxdamage -repeat -rfbauth /etc/x11vnc.pwd -rfbport 5900 -shared -capslock -nomodtweak ExecStop=/usr/bin/x11vnc -R stop Restart=on-failure [Install] WantedBy=multi-user.target client: vnc viewer v.7.0.1 i did encounter delays and random disconnection several times but looks like it's expected: https://forums.linuxmint.com/viewtopic.php?t=277139 can we have a look at the logs under /var/log ? (please rm -rf /var/log before you copy the logs)

hello @ANDESSE, i'm afraid that the only way to upgrade it to 2.1.6 is to download the os and use software such as balena etcher to flash the whole system. apt update && upgrade will only update the related debian packages

hello @Fuchsy, sounds like it's system hang to me from what you've described (even vnc is not working), we've not had this issue before, could you check the following: 1. if this hdmi panel is connected to usb touch, does the issue persist withouth usb touch? 2. does the issue persist without connecting to vnc? 3. does this issue happen when you're using other hdmi monitors? 4. does the mouse work when the issue occurrs?

hello @RichUK, there's no audiojack on tinker board 2s so i guess you're not using buttons on wired headphones for voice control? are you using wireless headphones or usb peripherals? volume control should work though

hello @hyewon, from the data you've provided, looks like you will need a MIPI converter board, also the panel has to meet the sequencing requirement; from software perspective, we don't know the ic chip so it's really hard to tell whether this panel is compatible with tinker board 2s or not. here are some of the supported panels:

hello @Justus, 1. download any of the tinker edge t os from: Tinker Board (asus.com) here i downloaded the latest version, which is mendel-eagle v.3.0.7 2. all the tools needed (android usb windows driver, adb, fastboot script ...) are located in the folder 'tools' >>Tinker_Edge_T-Mendel-Eagle-V3.0.7-20210610.zip\Tinker_Edge_T-Mendel-Eagle-V3.0.7-20210610\tools

hello @Aladonn, which tinker os did you use? and what version of anydesk have you installed? https://anydesk.com/en/downloads/linux?dv=deb_64

hello @stevenragy, these logs are common and can be ignored. we've checked with the chip vendor and are told that EGL are the ARM based OpenGL expansions for x window system, that's similar to glx on x86. Xorg uses Driver modelsettings to load libglx.so by default, libglx.so then looks up dri libs. however Xorg 2D accelerator uses DRM not dri libs so it prints the errors that you mentioned. i don't think the app can ever be executed if it's a GPU related issue, but it also depends on the mode the app's excuted (normal mode/ CLI mode) is it possible for use to have a look at the camera codes and dmesg?

hello @Mortis1369, sorry about the inconvenience, will check with team and get back to you shortly. are you developing an android 11 based os? Tinker Board 2 - Android (github.com)

to compile boot.img: source build/envsetup.shlunch WW_Tinker_Board_2-userdebug./build.sh -CKA it'll be located in directory: rockdev/Image-WW_Tinker_Board_2/

hello @shenouda, please refer to page 46, ch.8.13 "run with multi rknn tools" in Rockchip_Trouble_Shooting_RKNN_Toolkit_V1.7.3_EN.pdf rknn-toolkit/Rockchip_Trouble_Shooting_RKNN_Toolkit_V1.7.3_EN.pdf at master · rockchip-linux/rknn-toolkit (github.com)

hello @stevenragy, please try: sudo su cec-ctl --playback -o TinkerBoard2 cec-ctl -m and press the remote control keycode'd then show in the console

hello @joseph, libgpio requires gpio charcter device structure and it's only in kernel 5.0+ releases it's not supported on tinker edge r as its kernel version is 4.4 libgpiod - C library and tools for interacting with the linux GPIO character device (gpiod stands for GPIO device) Since linux 4.8 the GPIO sysfs interface is deprecated. User space should use the character device instead. This library encapsulates the ioctl calls and data structures behind a straightforward API. to build communications between tinker edge r and the 3d printer board, please refer to the '40 pin mapping table', sudo vim /boot/config.txt set the pin to =on, save, and reboot

hello @Fred, to run a shellscript at startup indeed you can edit rc.local, instead /home/linaro/start.sh, please try adjust it to: sudo bash /home/linaro/start.sh exit 0

hello @marco@bigsis.tech, yes, it'd be your (Cin0, Cin1, Cin2) for q #2 & #3, we've used netron to open the model inception_v4_299_quant.tflite, in quantization columns: to quantify with data range -1 ~ 1 -1 <=0.0089125 * (q – 128) =< 0.9921875 from this example it shows that the scale parameter = 128, and it's the same with mean parameter you will have to do it with models quantified, otherwise it'd be very confusing to set mean and std value we've asked the vendor and were told that it depends on whether the model's input data's been processed wile training or not.

hello @shenouda, tinker edge r is not in the codebase of adafruit blinka, you'll need to put the source of the board to it. please try using the attachment dht_simpletest.py instead of import board, please assign pins directly: import time #import board import adafruit_dht from microcontroller import pin # Initial the dht device, with data pin connected to: dhtDevice = adafruit_dht.DHT22(pin.GPIO2_B1) this is to connect dht22 data pin to pin3 of tinker edge r https://tinker-board.asus.com/tw/doc_er.html#GPIO dht_simpletest.7z

hello @Suntech, this error can be ignored, but we'll check it just in case. is it possible for us to know how to reproduce this? and how kivy was installed?

hello @dec, this is fixed in more recent releases, i've tested with v.2.1.6 and can confirm it works os images can be downloaded here: Tinker Board (asus.com)

hello @shenouda, have you tried adafruit dht circuit library? adafruit/Adafruit_CircuitPython_DHT: CircuitPython support for DHT11 and DHT22 type temperature/humidity devices (github.com) dht22 requires 3 pin connectors (vcc, gnd and gpio), you can use it on tinker edge r to install the package: pip3 install adafruit-circuitpython-dht --user details can be found here: https://github.com/adafruit/Adafruit_CircuitPython_DHT#readme
