What can i do?
Did you follow the guide from Bitmain? The link already posted above by me.
If the led is not flashing or blinking while you are flashing it with SD card it means that your SD card is not detected.
Here's what I think why it's not flashing.
- Possible your SD card is fake and the image you put become corrupted due to fake SD card(Try to replace with original one)
- Or maybe the SD card socket is full of dirt(Cleaning it might solve the issue.)
- Or maybe the file that you download is corrupted(Redownload the file image and make a new control board recovery again.)
Why not try to play the multi-option first under "Miner Configuration" you can find the working mode under this page and set it to "Low Power Enhanced Mode" then test the miner again.
Let's see if it solves your issue.
