The SAM-BA boot principle:

Once the communication interface is identified, to run in an infinite loop waiting for different commands as shown
in 



Mode commands:

̶

Normal mode configures SAM-BA Monitor to send/receive data in binary format

̶

Terminal mode configures SAM-BA Monitor to send/receive data in ASCII format



Write commands: Write a byte (O), a halfword (H) or a word (W) to the target 

̶

Address: Address in hexadecimal

̶

Value: Byte, halfword or word to write in hexadecimal



Read commands: Read a byte (o), a halfword (h) or a word (w) from the target

̶

Address: Address in hexadecimal

̶

Output: The byte, halfword or word read in hexadecimal



Send a file (S): Send a file to a specified address

̶

Address: Address in hexadecimal

Note:

There is a time-out on this command which is reached when the prompt ‘>’ appears before the end of the command 
execution.



Receive a file (R): Receive data into a file from a specified address

̶

Address: Address in hexadecimal

̶

: Number of bytes in hexadecimal to receive



Go (G): Jump to a specified address and execute the code

̶

Address: Address to jump in hexadecimal



Get Version (V): Return the SAM-BA boot version

Note:

In Terminal mode, when the requested command is performed, SAM-BA Monitor adds the following prompt sequence 
to its answer: <LF>+<CR>+'>'.
