DBGU Serial Port
Table 21-1.
Note:
Communication is performed through the DBGU serial port initialized to 115200 Baud, 8, n, 1.
The Send and Receive File commands use the Xmodem protocol to communicate. Any terminal
performing this protocol can be used to send the application file to the target. The size of the

• Write commands: Write a byte (O), a halfword (H) or a word (W) to the target.
• Read commands: Read a byte (o), a halfword (h) or a word (w) from the target.
• Send a file (S): Send a file to a specified address
• Receive a file (R): Receive data into a file from a specified address
• Go (G): Jump to a specified address and execute the code
• Get Version (V): Return the SAM-BA boot version
