This tutorial provides a step-by-step guide for flashing the D7 miner using an SD card. By following these instructions, you will be able to update the firmware of your D7 miner using this method. Ensure that you have the necessary hardware tools and software before proceeding.

Tools Needed

Before you begin, make sure you have the following tools ready:

  1. Hardware: PC (running Windows), TF card reader, TF card.
  2. Software: Decompression tool (such as WINRAR), D7 Card Flashing firmware.

Steps to Antminer D7 Flashing

Part I: Preparing the Tools

  1. Download the D7 Card Flashing firmware and save it on your computer.
  2. Use a decompression tool (e.g., WINRAR) to extract the downloaded firmware. Right-click on the firmware file, select “Unzip File,” and click “OK” to extract the files.
  3. Insert the TF card into the TF card reader and connect the card reader to a USB port on your computer.
  4. Your computer will recognize the TF card as a new device and assign it a disk letter (e.g., E:). Make a note of this disk letter.

Part II: Making the TF Card

  1. Format the TF card to the FAT32 file system. Right-click on the disk letter corresponding to the TF card (e.g., E:) and select “Format.”
  2. In the format dialog box, choose FAT32 as the file system and click “Start” to begin the formatting process.
  3. Confirm the deletion of all data on the TF card if prompted. Make sure to back up any important data before proceeding.
  4. Wait for the formatting process to complete and click “OK” when a confirmation dialog appears.
  5. Open the extracted firmware folder and copy all the files from the folder to the root directory of the TF card.
  6. Verify that all the files have been successfully copied to the TF card by checking the file names, sizes, and number of files.

Part III: Flashing the Miner

  1. Power off the miner (or separate control board) and insert the prepared TF card into the designated slot.
  2. Power on the miner (or control board) to start the flashing process.
  3. The indicator lights on the miner will go through a specific sequence:
    • The two lights will remain on for about 3-5 seconds.
    • The two lights will turn off for about 10 seconds.
    • The green light will remain on continuously.
  4. When the green light stays on continuously, it indicates that the flashing process is complete.
  5. Power off the miner (or control board) and carefully remove the TF card by pressing it inward and then pulling it out.
  6. Power on the control board again and log in to the miner’s backend to verify if the firmware version matches the flashed version.
