DBGU Serial Port
Supported External Crystal/External Clocks
Xmodem Protocol
Note:
Communication is performed through the DBGU serial port initialized to 115200 Baud, 8 bits of
data, no parity, 1 stop bit.
The SAM-BA Monitor supports a frequency of 12 MHz to allow DBGU communication for both
external crystal and external clock.
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
binary file to send depends on the SRAM size embedded in the product. In all cases, the size of
the binary file must be lower than the SRAM size because the Xmodem protocol requires some
SRAM memory in order to work.
The Xmodem protocol supported is the 128-byte length block. This protocol uses a two-charac-
ter CRC-16 to guarantee detection of a maximum bit error.
Xmodem protocol with CRC is accurate provided both sender and receiver report successful
transmission. Each block of the transfer looks like:
<SOH><blk #><255-blk #><--128 data bytes--><checksum> in which:
• 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 Boot Program version
