Command Data Stream Protocol
All commands are sent using the same flow. Each frame sent by the host is echoed by
the bootloader.
Figure 26.
Command Flow
Write/Program Commands
This flow is common to the following frames:
Flash/EEPROM Programming Data Frame
EOF or Atmel Frame (only Programming Atmel Frame)
Config Byte Programming Data Frame
Baud Rate Frame
Bootloader
":"
Sends first character of the
Frame
If (not received ":")
Else
Sends echo and start
reception
Sends frame (made of 2 ASCII
characters per Byte)
Echo analysis
Gets frame, and sends back ec
for each received Byte
Host
":"
