Return to the BootWare main menu, and enter the file control submenu to set the application as the
main application. The system will boot with this application at the next boot. For more information about
how to set the main application, see Set the selected file as the main application program (loaded when
the system starts). .
2) If the input file name is the same as the existing one, the system prompts:
The file is exist,will you recover it? [Y/N]
z If you select Y, the system overwrites the original application, and the AP boots with the new
application at the next boot.
z If you select N, the system prompts:
Cancel to overwrite the file.
Failed!
The system cancels overwriting the existing application, and the upgrade fails.
The size of an application is typically big. Even if you change the baud rate to 115200 bps, the upgrade
process takes about 30 minutes. Therefore, it is recommended that you upgrade an application through
an Ethernet.
Upgrading Applications Through TFTP at the CLI
The Trivial File Transfer Protocol (TFTP) is a TCP/IP protocol used for file transfer between client and
server. It provides a simple and low-overhead file transfer service. TFTP provides unreliable data
transfer over UDP and does not provide any access authorization and authentication mechanism. It
employs the timeout retransmission method to implement best-effort delivery of data. Compared with
FTP, TFTP has a much smaller software size.
