The way openwrt adds the tftp command is fixed, and the specific steps are as follows:

Set a fixed IP address

Go to cmd and type cd c:

tftp -i put wnr2200_factory_3.A message will appear when the tftp command is successfully sent, which means that the tftp command has been added successfully.

Note: Before executing the TFTP command, please power on the router, hold down the QSS key, wait for the LED to flash and then release it, and connect the router to the computer to create a TFTP server.

If the tftp under cmd does not send a message successfully, it means that there is a problem with the sending, please try again.
