hello @snk, please try: su linaro export DISPLAY=:0 xrandr --output HDMI-1 --off or you can disable hdmi in kernel: sudo su echo off > /sys/class/drm/card0-HDMI-A-1/status (if you'd like to enable it, then it's echo on > /sys/class/drm/card0-HDMI-A-1/status )

hello @snk, you can turn it off with xrandr: xrandr --output HDMI-1 --off

hello @snk, the boot sequence is sd card -> emmc; if you have a sd card in the slot it's likely that the board will boot from sd. if you'd like to keep the micro sd card inserted, you have to either 1. format it, or 2. un-partition the sd card -- the easiest way would be just leave the sd card slot empty so the system boots from emmc.

hello @Hashimoto Kenichi, 1. are you using tinker os? 2. what's the error you encountered? to write in uboot: 1. connect tinker board 2s to an ubuntu machine (tinker board 2s should be in ums mode while connecting) 2. press any key during booting to enter u-boot 3. here's an example using setenv/ printenv, and then savenv 4. saveenv and reboot, printenv test and it returns the right value

hello @sk109sk, please add it in /boot/cmdline.txt instead sudo vim /boot/cmdline.txt add this line, save and reboot spidev.bufsiz=65536 you can check the value with: cat /sys/module/spidev/parameters/bufsiz

hello @btwin, this issue can be reproduced on our side and we're working on it, will keep you updated when it's fixed

hello @manaasch, have you tried using a newer os? does this persist in every version of the os you're using?

hello @Yakiug, 1. tinker board 2s might be in maskrom mode, please check if you have a jumper attached, if so, please remove it so the board stays in normal mode 2. another possibility is using an incompatible os, tinker board and tinker board 2s have separate img files and they can't be mixed used https://tinker-board.asus.com/download-list.html?product=tinker-board-2s

hello @saeed soleimanifar, the fastest way to remove the 6 logos while booting, without re-compiling the kernel is to add quiet in /boot/cmdline.txt: consoleblank=1 quiet you can change it in monitor setting: toolbar >preferences> monitor settings

hello @saeed soleimanifar, you can get the console log disabled by modifying the /boot/cmdline.txt: console= save and then reboot

hello @KMO, you can get it working properly by removing the ntp package: sudo apt-get remove ntp if you do not wish to remove ntp, you can comment out the line below in /lib/systemd/system/systemd-timesyncd.service.d/disable-time-daemon.conf # ConditionFileIsExecutable=!/usr/sbin/ntpd reboot and then update the system with sudo apt-get update check jobs with: systemctl list-jobs

hello @saeed soleimanifar, by boot logs, do you mean the console logs printed whist booting?

hello @Buchhalter, 1. was the usb camera working with the previous os releases? 2. what’s the usb camera you’re using? 3. what’s the output when you execute v4l2-ctl --list-devices

hello @Lucas32, this guide from toradex explains what device tree overlays are and how they work: https://developer.toradex.com/linux-bsp/os-development/build-yocto/device-tree-overlays-linux/ reboot is needed after you sudo vim /boot/config.txt what is the os version? the dtbo of dac hats in the qualified vendor list are already built out/ included in the os. you might want to an os that's later than v.2.1.6 Tinker Board 2 Debian 10 V2.1.6 Description Tinker Board 2 Debian 10 V2.1.6 Tinker OS default username is "linaro", password is "linaro".

hello @btwin, yes, tinker-config is also supported for tinker board r2.0, you can download v.3.0.11 here: Tinker Board S R2.0 Debian 10 V3.0.11 to disable auto-login using tinker-config: sudo tinker-config in ther terminal prompt: 1. select "3. Boot Options" 2. select "B1 Desktop" 3. select "B3 Desktop" 4. finish the prompt will ask you to reboot the board so the new setting comes in effect. i would suggest to power off the board and re-power it again, just in case.

hello @Suntech, the easiest way would be using the dd command to clone everything out of the board then use flashtools such as balena etcher to flash the .img to other boards. 1. connect tinker board 2s to an ubuntu machine 2. to check if tinker board 2s has been recognised, use lsblk 3. to clone the eMMC: sudo dd if=/dev/sdb of=(filename).img bs=1G this will take a while, i've waited for around 35 minutes or so 4. once the cloning is finished, copy the .img file and use flashtools such as balenaetcher to flash the os to other boards *if you don't have an ubuntu machine, you can plug a flash drive to tinker board 2s, and save the output file to the flashdrive (please ensure it's got enough space) change #3 to: sudo dd if=/dev/sdb of=of=/dev/<USB device_name> bs=1G **if you're using a windows pc, you can use win32 disk imager: Win32 Disk Imager - Download [Official Site] 1. connect tinker board 2s to the pc 2. whilst tinker board 2s is in ums mode, use win32 disk imager to copy the emmc Using dd to clone eMMC OS.pdf

hello @giseleznev, 1. which adc are you using? do you have a product link so i can check the spec? 2. may i have a look at how the sound card is connected to tinker board 2s?

hello @Lucas32, the sensor setting for imx219 is 1920x1080 by default, you can change it to 3840x2160 with commands: media-ctl -d /dev/media0 --set-v4l2 '"rkisp1-isp-subdev":0[fmt:SRGGB10_1X10/3840x2160]' media-ctl -d /dev/media0 --set-v4l2 '"rkisp1-isp-subdev":0[crop:(0,0)/3840x2160]' media-ctl -d /dev/media0 --set-v4l2 '"rkisp1-isp-subdev":2[fmt:YUYV8_2X8/3840x2160]' media-ctl -d /dev/media0 --set-v4l2 '"rkisp1-isp-subdev":2[crop:(0,0)/3840x2160]' media-ctl -d /dev/media0 --set-v4l2 '"m00_b_imx219 1-0010":0[fmt:SRGGB10_1X10/3840x2160]' v4l2-ctl -d /dev/video0 --set-fmt-video=width=3840,height=2160,pixelformat=NV12 --set-crop=top=0,left=0,width=3840,height=2160

hello @giseleznev, this is the qualified vendor list of tinker board 2s: https://tinker-board.asus.com/images/doc/download/Tinker_Board 2_QVL_Devices 20210324.pdf

hello @hisataro, what are the error messages/ logs? i'll check if there's anything been changed

hello @giseleznev, should be there once you repo sync if you're not using docker, run ./build.sh if you're using docker then ./docker_builder/docker-builder-run.sh build.sh

hello @hisataro, updated to the developer guide, thank you for the reminder Developer Guide · TinkerBoard/TinkerBoard Wiki (github.com)

hello @giseleznev, what is the os version you're using and can we have the screenshot of the aplay -l result for checking? the 'hdmi-dp-sound' is an old structure that does not exist anymore, i don't have a pisound but if its chip is pcm5102a then 'overlay=hifiberry-dac' may work. please use v.2.1.6 (debian 10, kernel 4.19) or later versioin Tinker Board 2 Debian 10 V2.1.6
