RogueFox37 0 Posted March 11 Hello all, I am new to single board computers. I just got my tinker edge R yesterday. After watching several videos I finally managed to figure out how to flash debian to my sd and get my device to boot up. After a quick look around, I realized that setting up a wireless connection was not going to be straight forward like on windows and figured that I should probably go with andriod for ease of use. I so far only have plans to use this Edge R as an emulator machine for my kids and I. I formatted the SD card again and this time again used Balena Etcher, but this time tried to install Android 9 V1.0.6 downloaded from the support page. Etcher said that everything was flashed successfully, but when I power up my device, no signal is found on the monitor weather I use USBC or HDMI. I've left it powered on for several minutes as well and tried a different monitor. When flashing, the file I chose was the "update.img" found in the main directory. One of the videos I watched said to use that file and then just hit continue when it said it was missing partitions or something like that. What am I doing wrong? Any help would be greatly appreciated. Share this post Link to post Share on other sites
tooz 47 Posted March 12 hello @RogueFox37, you will need to plug a m.2 wireless networking card to make the wifi work, here i'm using liteon rtl8822ce, and then go to settings: wi-fi and then choose the network you might want to have a look at the qualified vendor list to choose the components that are supported on tinker edge r: https://tinker-board.asus.com/download/Tinker_Edge_R_Device_QVL.pdf Share this post Link to post Share on other sites
tooz 47 Posted March 12 if you'd like to flash tinker edge r back to debian os from android, please enable ums before flashing; please note that a m.2 wifi card is necessary in order to make wifi work, so be sure to install it before flashing: 1. power on tinker edge r, connect it to the pc with a usb-type c cable (type c port: tinker edge r, type a port: pc), and download the adb platform tools from android developer: https://developer.android.com/tools/releases/platform-tools (i'm using a windows laptop so i downloaded the tools for windows) 2. unzip the file and excute adb.exe 3. open a terminal -- you can do so by typing 'cmd' on the bar 4. use 'adb devices' to check if tinker edge r is listed, if it shows nothing, maybe you want to do 'adb kill-server' and try again adb devices 5. use 'adb reboot ums' to reboot tinker edge r (& keep it in ums mode) adb reboot ums 6. download balenaetcher: https://etcher.balena.io/ click 'flash from file' and select the .img (in my case Tinker_Edge_R-Debian-Buster-v2.0.5-20220217.img ) select 'linux ums disk usb device' (which is tinker edge r) as drive, and then flash 7. unplug the usb type c cable and reboot tinker edge r -- it will reboot twice, which is expected 8. when it boots into the system, click the computer icon next to the bluetooth icon on the lower right to select wifi network Share this post Link to post Share on other sites
