SAM-BA Monitor
The SAM-BA boot principle:
Once the communication interface is identified, to run in an infinite loop waiting for different commands as shown
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.
̶
Output
: ‘>’.
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 following by ‘>’
Send a file (S): Send a file to a specified address
̶
Address
: Address in hexadecimal
̶
Output
: ‘>’.
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
̶
NbOfBytes
: Number of bytes in hexadecimal to receive
̶
Output
: ‘>’
Go (G): Jump to a specified address and execute the code
̶
Address
: Address to jump in hexadecimal
