hello @Al Avitr / @jravi24, what are the touchscreens you're using? is it possible for you to get the syslogs?

hello @altairthecloak, you'll have to modify the overlay: /dtoverlay/config.txt https://github.com/TinkerBoard/TinkerBoard/wiki/Developer-Guide#how-to-configure-gpio-as-an-individual-function-and-the-function-work

hello @M@riusz, it's for tinker board 2s

hello @M@riusz, please check if you can configure mcp2515 with the os: Tinker_Board_2-Debian-Buster-v2.0.18-20221207.zip

hello @ksh, you can modify the cmdline.txt in /boot/ to diasble autosuspend: sudo vim /boot/cmdline.txt add the following line: usbcore.autosuspend=-1 just delete this line if you'd want to enable autosuspend again (which means set it back to default)

hello @marco@bigsis.tech, it depends on how the original model is trained -- in the document of rknn toolkit, ch. 3.2.2: rknn-toolkit/Rockchip_User_Guide_RKNN_Toolkit_V1.7.3_EN.pdf at master · rockchip-linux/rknn-toolkit (github.com) listed the quantize sizes supported; using low precision integer will indeed make the inference faster these are warning messages and should not be affecting anything as long as the model gets built out.

hello @cagatay, since there's no kern.log for android, is it possible for you to boot the board, connect the panel to the board with the type c cable, unplug the cable, and save the log? logs can be saved with this command using adb: adb shell dmesg > kernel.log

hello @cagatay, you probably need to modify your app, some examples: Automatically Run An Application On Android Phone Startup With Examples (folkstalk.com) https://stackoverflow.com/questions/60699244/boot-completed-not-working-on-android-10-q-api-level-29/63250729#63250729

hello @cagatay, i see. i was thinking that you're using debian os -- if you're using debian, then i can check the processes from /var/log/kern.log and see if the panel's been recognized. are you using the official release android 11 os from Tinker Board (asus.com) ?

hello @cagatay, what's the hardware and software version you're using? (tinker board 2s or tinker board 2? debian 10 v.?? or android v.??) is it possible for you to: 1. boot the board 2. connect the display to the board 3. save the output of /var/log/kern.log we'll check the log and investigate the problem

hello @hoser, win32 disk imager is the other alternative

hello @Sauer, we're still checking the issue, but from the logs and the information you've provided, looks like certain usb ports are not working properly -- this happens usually when the board is overheating -- do you by any chance have another touch panel to cross-examine?

hello @marco@bigsis.tech, this is processed by cpu only. this is the reference for rknn-toolkit for model conversion, inferene ... etc https://github.com/rockchip-linux/rknn-toolkit here's an example on converting tflite model to rknn model: https://github.com/rockchip-linux/rknn-toolkit/tree/master/examples/tflite/mobilenet_v1

hello @marco@bigsis.tech, for your refernce:

hello @Poko-san, we've used v.2.1.6 & v.2.0.14 for uvc testing, using cheese: you will have to switch to usb camera first, to do so, please use the "Camera Product Name" 1. you can check the Product Name with the following command in lxterminal: $ udevadm info /sys/class/video4linux/video5 | grep ID_V4L_PRODUCT ID_V4L_PRODUCT=Logitech Webcam C930e in this case the Camera Product Name is "Logitech Webcam C930e" 2. then you can open the camera with the command: $ cheese -d “Logitech Webcam C930e” we've tested 1080p/480p MJPG & YUYV configs with qv4l2 and both configs work. may we know which usb cam you're using and the configs? we've used another unknown branded usb web cam and have noticed that unstable connection can lead to failure such as cheese:1291): cheese-WARNING **: 10:17:11.512: Failed to allocate required memory.: gstv4l2src.c(658): gst_v4l2src_decide_allocation (): /GstCameraBin:camerabin/GstWrapperCameraBinSrc:camera_source/GstBin:bin29/GstV4l2Src:v4l2src2: Buffer pool activation failed

hello @Sauer, thanks for the info, to further the analysis it would be helpful to know: 1. When the problem occurred, were display and touch both not working? 2. When you rebooted the board, did it fix the issue? Or did it still persist? 3. Have you tried reboot the board or unplug/ replug hdmi and usb cable instead of changing to another board when it’s not working? from the logs we’ve seen usb being connected and disconnected, looks like the usb connector is broken, we’d suggest use another usb cable or panel to connect -- it's normal that cables get fraying over time. we'll keep looking into the issue though Nov 26 12:05:51 tinkerboard kernel: [ 4.653372] usb 1-1.3: USB disconnect, device number 4 Nov 26 12:05:51 tinkerboard kernel: [ 5.075529] usb 1-1.3: new full-speed USB device number 5 using dwc2 Nov 26 12:05:51 tinkerboard kernel: [ 5.178409] usb 1-1.3: New USB device found, idVendor=1a86, idProduct=e5e3 Nov 26 12:05:51 tinkerboard kernel: [ 6.445379] usb 1-1.3: USB disconnect, device number 5 Nov 26 12:05:51 tinkerboard kernel: [ 6.755533] usb 1-1.3: new full-speed USB device number 6 using dwc2 Nov 26 12:05:51 tinkerboard kernel: [ 6.858572] usb 1-1.3: New USB device found, idVendor=1a86, idProduct=e5e3 Nov 26 12:05:51 tinkerboard kernel: [ 7.981017] usb 1-1.3: USB disconnect, device number 6 Nov 26 12:05:51 tinkerboard kernel: [ 8.425481] usb 1-1.3: new full-speed USB device number 7 using dwc2 Nov 26 12:05:51 tinkerboard kernel: [ 8.527415] usb 1-1.3: New USB device found, idVendor=1a86, idProduct=e5e3

hello @Poko-san, i've used tinker board 2s with debian 10 v.2.0.14 installed qv4l2 test utility, cheese and vlc - there's some compatibility that i cannot use cheese to take/ preview photos or videos using qv4l2: open qv4l2 -> open device -> select video5 -> start capturing uvc running successfully i've tried using vlc media player: open media -> capture device -> video device name '/dev/video5' in my case and it works too what's the usb video camera you're using? i'll look into the issues happened in cheese too, but if it's a compatibility limitation, we'd suggest to use another package

hello @marco@bigsis.tech, this is the imshow function error, perhaps you want to check and adjust the import frame

hello @JasonS, for rk3399/ v8 there's no zImage, you will have use Image instead, try: make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j4 make Image ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j8

hello @paul_nicholls, this is a tinker board '1.2' with no emmc (rk3288 based), you can download one of the images and burn it into microsd with balenaetcher android 12: Tinker Board R2.0 /Tinker Board S R2.0 Android 12 V0.0.3 debian 10: Tinker Board S R2.0 Debian 10 V3.0.11

hello @Sauer, what's the 7" touchscreen display? is it a rpi touch screen? and you're using hdmi connector instead of dsi, right? whats the syslog looks like? may we check this?

hello @marco@bigsis.tech, so the version of opencv-python was upgraded, if you've encountered import cv2.imshow() error, please remove the build-in opencv-python: python3 -m pip uninstall opencv-python then re-install: python3 -m pip install opencv-python --user

hello @marco@bigsis.tech, forgot to mention that if you're using the releases from us: https://tinker-board.asus.com/download-list.html?product=tinker-edge-r the script file of rknn toolkit installation is included (you can find it on desktop) no need to install opencv as it's included in the toolkit installation

hello @marco@bigsis.tech, i was testing tinker board 2s and did manage to compile opencv: sudo apt-get update sudo apt install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev git clone https://github.com/opencv/opencv.git cd opencv/ git checkout 4.1 mkdir build cd build cmake -D CMAKE_BUILD_TYPE=RELEASE \ -D INSTALL_C_EXAMPLES=OFF \ -D PYTHON_EXECUTABLE=$(which python3) \ -D BUILD_opencv_python2=OFF \ -D PYTHON3_EXECUTABLE=$(which python3) \ -D WITH_GSTREAMER=ON .. make && sudo make install will check on tinker edge r and let you know
