  1. 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
  2. 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
  3. hello @Sauer, what's the 7" touchscreen display? is it a rpi touch screen? and you're using hdmi connector instead of dsi, right?
  4. 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
  5. 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
  6. 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
  7. hello @marco@bigsis.tech which version of opencv were you building? were you building it on tinker board 2s?

    Not recognize emmc

    hello @CardeLL, try 're-writing the os using ums from a micro sd card': User-Manual.pdf (asus.com)
  9. hello @yshs, https://www.asuswebstorage.com/navigate/a/#/s/CB6E83A0F01F4669A3D543A7DB864EB14 1. download 'console-uart1-overlay.dtbo' file from the link above 2. move the file to /boot/overlays 3. sudo vim /boot/config.txt to enable console-uart1 (overlay=console-uart1-overlay) 4. reboot
  10. hello @Francois, you'll need to resize SSD partitions before moving the root files into SSD. what editing boot.txt does only is to direct where to mount for rooting
  11. hello @Francois, please edit mmc_root as your kernel still runs on emmc; you can use root path (i.e. /dev/nvme0 ...etc) instead of partuuid
  12. hello @Francois, what reboot-bootloader does is to look for partable misc partition, please make sure there's a misc partition for booting
  13. hello @Francois, there's a slight difference between tinker board (rk based) and tinker edge t (nxp based), please edit the root path for kernel cmdline and recompile: directory: packages/uboot-imx/debian/boot.txt ( mendel-uboot-imx-debian/boot.txt at mendel-imx_8m · TinkerEdgeT/mendel-uboot-imx-debian · GitHub ) line 4 and line 5 mmc_root="PARTUUID=70672ec3-5eee-49ff-b3b1-eb1fbd406bf5" sd_root="/dev/mmcblk1p2" change the sd_root= to your ssd UUID and recompile/ reflash
  14. hello @Goolge, try this .py: https://www.asuswebstorage.com/navigate/a/#/s/845A267A0B6E4346BF90E84D32F8A8C84 -- import cv2 def main(): cap = cv2.VideoCapture('/dev/video10', cv2.CAP_V4L2) cap1 = cv2.VideoCapture('/dev/video12', cv2.CAP_V4L2) while(True): ret, frame = cap.read() ret, frame1 = cap1.read() cv2.imshow('Camera 1', frame) cv2.imshow('Camera 2', frame1) if cv2.waitKey(1) & 0xFF == ord('q'): exit = True break cap.release() cv2.destroyAllWindows() if __name__ == '__main__': main()
  15. hello @denchakapon, we still have a couple of arrangement to make and hopefully get android 12 source code for tinker board r2.0 uploaded by the end of next week. will keep you informed
