    Select the test that should be run, and press the “Run” button to start the test. Finally, the test program will show the status of the test. Note: AVR Studio 4.0 or later is required for ICE50 support. AVR Studio 3.x versions will not work with ICE50! Tip! AVR Studio is constantly being updated.

  • Page 35: Connecting Ice50

    AVR Studio can not force control over a COM port. If other equipment or software driv- ers have control of the COM port (eg. IrDA, PDA, Scanner.. ) communication with the ICE50 will fail. Make sure that no other software has control of the COM port that ICE50 is connected to.
  • Page 36 Connecting ICE50 connecting or disconnecting the ICE50 from the host PC, make sure that the ICE50 is not powered. 1. Inserting the personality adapter. Make sure that pin 1 on the personality adapter corresponds with pin 1 on the target socket/footprint.

  • Page 38: Ice50 Power-Up Sequence

    Once the Probe and Personality Adapter are connected, continue by correct Power-up sequence. ICE50 Power-up When the ICE50 is properly connected to the target and the host PC, the power can be turned on. The following procedure is recommended to ensure proper communication Sequence between the ICE50 and AVR Studio.

  • Page 39: Configuring Avr Studio

    Section 5 Configuring AVR Studio When the ICE50 is properly connected to the target application, the next step is to set up the correct device configuration in AVR Studio. This is required when an application project is opened for the first time, and can later be changed in the emulator options menu.
