EdwardKhoh 1 Posted April 21, 2021 May I know how can i boot the Think OS by using SD Card instead of eMMC Share this post Link to post Share on other sites
tooz 51 Posted April 23, 2021 hello @EdwardKhoh for Tinker Board/ Tinker Board S, please refer to this page: https://tinkerboarding.co.uk/wiki/index.php/Setup#Setting_up_your_SD_card 1. if you're using a Tinker Edge T, please unzip the image file downloaded from https://tinker-board.asus.com/download-list.html?product=tinker-edge-t 2. there will be an .img file named "sdcard_arm64" in the folder. you can use either Win32DiskImager or balenaEtcher to flash your SD card with this .img file 3. if you flip the board, there are 4 switches on the back of Tinker Edge T, please switch it to "ON, OFF, ON, ON" so the board is enabled booting from SD card please note that you will have to put the switch back to "ON, OFF, OFF, OFF" if you wish to boot from eMMC Share this post Link to post Share on other sites
drluckyspin 0 Posted July 26, 2021 (edited) After following these instructions I get nothing. I: Wrote `sdcard_arm64.img` to SD card Made jumpers were ON, OFF, ON, ON Put in power All I see is the red LED on on the board. The heat sink fan is spinning. My attached monitor did flick to black from "No input" but there is no output whatsoever. No console or boot output. How do I diagnose what is wrong?

Khoh Choon Hwa 0 Posted July 29, 2021 Hi Tinker Engineer, Thanks for your technical info. I can boot the TInker Edge S from SDCard. May i know how about the Tinker Edge R? Can you please advice? Share this post Link to post Share on other sites

EdwardKhoh 1 Posted September 13, 2021 Thanks for the reply. I will try out the suggested sulotion. I have another question. The Tinker Edge R has ARM® Mali™-T860 MP4 GPU @ 800 MHz for machine learning application running. Is there any software that for my reference to accelerate the workload by this GPU?

tooz 51 Posted September 14, 2021 hello @EdwardKhoh if you're developing machine learning applications, you can use the NPU to acccelerate, here are some documents on RKNN: https://github.com/rockchip-linux/rknn-toolkit/blob/master/doc/Rockchip_User_Guide_RKNN_Toolkit_V1.7.0_EN.pdf https://github.com/rockchip-linux/rknn-toolkit Share this post Link to post Share on other sites

Hi, I also have the exact same problem and have been unable to resolve it. I am afraid I ran out of options, tried everything suggested in the forum. Share this post Link to post Share on other sites
