Find the correct UART interface according to your hardware's documentation.

6. Solder the FTDI outputs to the UART pins on the board.

7. Open Device Manager, plug in the FTDI USB and find the COM port (e.g. COM3).

8. Run Putty with the appropriate COM port:

putty.exe -serial COM3 -sercfg 115200,8,n,1,N

9. A Putty window will open.

15. If after the third command the download does not happen — check the TFTP server settings.

Tip

Make sure a firewall or antivirus is not blocking the TFTP server.
