hello @Vincent123, i haven't tried installing docker on debian 9, which version of tinker os and what's the error you're seeing?

hello @Poko-san, which dac are you using? also i would suggest to use the latest os version for testing: https://tinker-board.asus.com/download-list.html?product=tinker-board-2s#download20220926

hello @Poko-san, i've made a simple tutorial video: (in this video, i use 'justboom dac hat', but not all dac hats are compatible, please check before use) prerequisites: -tinker board 2s -a dac that's compatible with tinker board 2s steps: 1. check the supported dtb with command $ ls /boot/overlays/ 2. edit overlay with command (last line of the .txt, in this example it's overlay=justboom-dac) $ sudo vim /boot/config.txt 3. save the modified .txt esc+shift+: wq 4. turn off tinker board 2s 5. insert the dac 6. power on tinker board 2s 7. check if the dac is recognized with command $ aplay -l 8. use volume control to adjust volume, there's a build in media player, in this example i've downloaded and used rhythmbox ( https://debian.org/Rhythmbox ) please note: 1. check the compatibility before use 2. the 40-pin gpio header gets damaged very easily with unnecessary ic contacts, please be very careful when connecting the dac to tinker board 2s

the bootflow of tinker board 2s is different from tinker board and editingi /extlinux.conf will not work on tinker board 2s

hello @sathish, if you'd like to change it permantly, you can use systemd-timesync only and remove ntp enable systemd-service first: sudo systemctl enable systemd-timesyncd.service remove disable-with-time-daemon.conf as it's causing dependency conflict: rm /lib/systemd/system/systemd-timesyncd.service.d/disable-with-time-daemon.conf disable/ stop ntp: sudo systemctl stop ntp sudo systemctl disable ntp you can check the result with timedatectl reference: https://www.mail-archive.com/debian-bugs-dist@lists.debian.org/msg1800695.html

hello @ethan, it might be a power supply issue if the led is flashing, please make sure you're using an adapter that provides sufficient power Power Connector (up to 65W) 1 x 12~19V DC Power Input Jack (5.5/2.5mm) 1 x 12~19V 4-pin DC Power Input Header it might be worth trying to flash os to another sd card, put it into tinker edge r (once flashing is done) connect it to nothing but windows pc and see if it enters ums mode -- it would be great if you could record the issue so we can have a closer check

if you see 'flash has failed' you will need to remove the jumper and try reflash again

connect tinker edge r to pc with type c cable, make sure the jumper is inserted before booting. to check whether tinker edge r is in maskroom mode, open device manager and look for 'rock usb devices'

hello @ethan, does the issue persist without having the quectel ec25-af module installed? i made a short video on how to flash tinker edge r with balena etcher for your reference:

to enter maskrom mode you’ll need to use a jumper to short the recovery header the set of pins next to the fan pins before booting https://tinker-board.asus.com/images/doc/download/Tinker_Edge_R_Getting_Started.pdf

hello @giseleznev, PCM5102PW and PCM1804DBR are not supported at the moment

hello @ethan, which os version are you using and did you connect the tinker edge r to a pc (type-c <> usb) whilst booting? from what you've described sounds like tinker edge r has enter fastboot mode, please disconnect tinker edge r with pc and see if it can boot into system.

hello @sonyan11, i think you're able to modify uvcvideo driver to module mode through menuconfig, but tinker board 2s is not able to recognize the new module because the module driver is not updated to tinker board 2s. to update tinker board 2s' module driver, please execute these two commands in the kernel directory of the source code, make ARCH=arm64 modules make ARCH=arm64 modules_install INSTALL_MOD_PATH={INSTALL_PATH} and then update the \lib\modules\4.4.194\ kernel and \lib\modules\4.4.194\modules (of which from {INSTALL_PATH} ) onto tinker board 2s accordingly

hello @sathish, please make sure to set your mass storage/ disk access if it's on fat filesystem, or run your file manager as root sudo cp /disk/directory/rtc.json /home/linaro/Desktop/

hello @sathish, it is not built in the tinker os, if you'd like to use dhcpcd: sudo apt-get install dhcpcd5 the dhcpcd.con will be locaed in /etc/ alternatively, you can use nmcli con mod to configure the ip network

--volume=VOLUME Set initial playback volume to VOLUME, where 0.0=silent and 1.0=unchanged

hello @sathish, perhaps you can use gst-play-1.0, command: gst-play-1.0 FILE|DIRECTORY|URI [FILE2|DIRECTORY2|URI2] https://gstreamer.freedesktop.org/documentation/frequently-asked-questions/using.html?gi-language=c#how-do-i-use-the-gstreamer-command-line-interface

hello @snk, which version of os you're using for tinker board r2.0? iw phy i tried to reproduce it on tinker board r2.0 with the latest os, and the band 1 information wasn't missing: Band 1: Capabilities: 0x1962 HT20/HT40 Static SM Power Save RX HT20 SGI RX HT40 SGI RX STBC 1-stream Max AMSDU length: 7935 bytes DSSS/CCK HT40 Maximum RX AMPDU length 65535 bytes (exponent: 0x003) Minimum RX AMPDU time spacing: 16 usec (0x07) HT Max RX data rate: 150 Mbps HT TX/RX MCS rate indexes supported: 0-7

hello @ICE, you can use the gpio pins to implement MLX90640 IR Thermal Camera since it uses i2c to communicate instead of csi interface: https://github.com/melexis/mlx90640-library i don't have this camera module in hand right now, but cave education has done a demo using tinker board before: https://www.facebook.com/CAVEEducation/videos/1110440046181370/

hello @snk, to use iw commands you'll need to execute them with superuser priviledge: sudo iw phy

hello @sonyan11, for uvc option, the config has to be set with the command below before make menuconfig tinker board linux 4.19: make ARCH=arm64 tinker_board_2_defconfig and then make menuconfig

hello @sushil, to enable softap mode: Developer Guide · TinkerBoard/TinkerBoard Wiki (github.com) 1. for tinker board / tinker board r2.0, download https://github.com/TinkerBoard/TinkerBoard/files/8107749/SoftAP_debian10_20220127.zip and unzip the file 2. update packages and install dnsmasq and hostapd, then execute the shellscript to enable softap sudo apt-get update sudo apt install dnsmasq hostapd move to the SoftAP_debian10_20220127 directory, and execute the script (with root access) chmod 755 Enable_SoftAP.sh Disable_SoftAP.sh ./Enable_SoftAP.sh error rfkill: cannot open /dev/rfkill: No such file or directory can be ignored 1. to get wifi back to normal mode, please execute ./Disable_SoftAP.sh (otherwise it stays in softap mode after ./Enable_SoftAP.sh is executed) 2. when doing ./Enable_SoftAP.sh or ./Disable_SoftAP.sh if the error SIOCSIFFLAGS: Operation not possible due to RF-kill occurrs, please execute echo 1 > /sys/class/rfkill/rfkill0/state it is not recommended to use concurrent mode
