hello @sri, did you do step 4). which is to create defconfig?
-
hello @Jovan, thanks for letting me know. also, could you try use flash a sd card with v.1.0.17, and see if the first tinker board 3n can boot from sd and then flash emmc? Tinker Board 3N Debian 11 (Kernel 5.10) V1.0.17
-
hello @Jovan, given the clues i can only suggest to 1. restart the windows pc 2. change the type a - type c cable tinker board 3n should be recognised in device manager, as same as tinker board 2s (the quickest way to debug the environment is to plug a usb drive to the same port of the windows pc and see if it's working)
-
hello @Jovan, was the led (led1) on while using? please check if you're able to use the adb with mask2 cap on while booting?
-
hello @Jovan, 1. the connection should be type c port (tinker board 3n) to type a port (macbook) 2. both the jumper caps need to be removed 3. no need to adjust mask1 dip switch
-
hello @Jovan, please remove the yellow jumper cap, and re-do the procedure (connecting tinker board 3n to the computer) again booting without the jumper cap attached so the tinker board 3n can start on uboot and the board should be in ums mode
-
hello @Jovan, the cc logic controllers between tinker board 2s and tinker board 3n are different -- for tinker board 3n, if both the ports connected are type c port, the controller will not be able to recognise which port should be in host mode and which port should be in device mode. for tinker board 3n i would recommend to connect type c port from tinker board 3n to type a (macbook)

hello @raymjr, please have a look at: Tinker Board (asus.com)

hello @zain, here are some examples for your reference: https://github.com/rockchip-linux/rknn-toolkit/tree/master/examples/mxnet/fcn_resnet101 you can also check chapter 7.15 Export a segmentation model from 02_Rockchip_User_Guide_RKNN_Toolkit_V1.7.5_EN.pdf

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

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

hello @wiki11, good to know it works and thank you for the instruction
