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.

Setting Up an Upgrade Environment
