Windows File Extension Display

Windows may hide file extensions by default, which can mistakenly save the file as firmware.bin.txt or firmware.bin.bin. Before copying the firmware to the TF card, enable file extension display in File Explorer:

  1. Open any folder.
  2. Click View at the top.
  3. Check File name extensions.
  4. Confirm the full file name on the TF card is firmware.bin.
  1. Power off the motherboard and insert the TF card.
  2. Power on the motherboard and wait for 10 seconds.
  3. Remove the TF card and insert it into your computer. If the firmware.bin file disappears and a FLY.CUR file appears, the flashing was successful.
