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

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?

those steps were correct, we'll need console logs to see what exactly went wrong; perhaps there's something wrong with image, please make sure that 

1. .img file is in correct format, 2. the switches 1, 2, 3, 4 are: on, off, on, on, 3. after the switch adjustment, insert sdcard and power the board

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?

hello @EdwardKhoh

if you're developing machine learning applications, you can use the NPU to acccelerate, here are some documents on RKNN:

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.
