  1. Dear Tinker Board Community, I've been struggling for some time now, building an Yocto image for tinkerboard 2 (RK3399). I need networking and DRM support. The official Tinkerboard2 yocto-meta-rockchip has some broken kernel mirrors and fails building. If someone managed to build a working yocto image for tinkerboard 2, please give me some hints. Best regards!
  2. Hi, I'd like to connect two USB cameras (compliance with USB2.0) and configure 640x480 resolution both cameras. I don't care frame rate. Due to design reasons Type-C port is not available. Both camera works on 640x480@15fps on YUYV(4:2:2) when single connect, But 640x480 resolution is not works even if use lowest fps(5) when two camera connected. During operation, dmesg outputs this information. > usb 5-1.1.1: Not enough bandwidth for new device state. > usb 5-1.1.1: Not enough bandwidth for altsetting 11 this log is incomprehensible, Because USB2.0 has enough bandwidth to output in this configuration. I have suspicion kernel or device driver has any problems. environmental information: Device: Tinker Board 2S OS: TinkerOS Debian 10 V2.0.12 Camera A: ELECOM UCAM-C310FBBK Camera B: Arkmicro Technologies Unknown camera product (only supports YUYV(4:2:2) format) Would you tell me any advices or information if possible. regards, takuya
  3. Hi, I've downloaded the 4.19 kernel source from https://github.com/TinkerBoard2/kernel/tree/tinker_board_2-debian_10-2.1.6 and built with: make ARCH=arm64 tinker_board_2_defconfig make ARCH=arm64 rk3399-tinker_board_2.img -j8 Copied boot.img to SD card with dd if=boot.img of=/dev/mmcblk0p4 status=progress && sync Rebooted: the system is stuck at "Waiting for root device /dev/mmcblk0p9" What I did wrong? Thank you
  4. Hello, Do you know when a library for asus tinker board 2 or 2s will be available for GPIO in python? thank you
  5. I wanted to use an Arduino compatible machine and tried to make a driver for CH34x but couldn't. (Tinker Board 2 Debian 10 V2.0.0) I tried the method posted on this site. https://learn.sparkfun.com/tutorials/how-to-install-ch340-drivers/linux I put the linux header like this. wget https://github.com/TinkerBoard2/kernel/releases/download/tinker_board_2-debian_10-2.0.0/linux-headers-4.4.194_4.4.194-1_arm64.deb dpkg -i linux-headers-4.4.194_4.4.194-1_arm64.deb Has anyone succeeded? Or, if you have an installable ch34x.ko, I would appreciate it if you could share it. sudo insmod ch34x.ko As a side note, in the case of Tinker board S, Arduino compatible machines were recognized without installing any drivers. (Tinker Board S Debian 10 V3.0.11) Thank you.
