Using an Microchip (formerly Atmel) SAMV71-XULTRA board, I want to capture ETM Instruction Trace information, but I receive the following error:

How can I do this?


To successfully capture ETM Instruction Trace from this board you have to follow a certain connection - and power-up sequence.


Follow this connection and power-up sequence before starting a trace session:

  1. Ensure ULINKpro and development board are both NOT powered
  2. Connect ULINKpro's ribbon cable to the ETM+Debug connector of the development board
  3. Power up the board
  4. Power up ULINKpro by connecting the USB cable
  5. Start the Debug session


  • The Pack Installer installs the corresponding Packs which contain example projects
  • Make sure you are calling the attached initialization file SAMx7_TP.ini in the Initialization File: textbox at Options For Target - Debug.
