The OpenSDA connection is not available in the Connection page of the wizard. What do I do?

You can use the normal P&E Multilink connection instead. For that, you only have to change the Interface in the debugger settings from P&E Multilink to OpenSDA in the Connection tab.

To do this:

  1. Select Run > Debug Configurations from the IDE menu bar.
  2. Select the desired build configuration from the left panel.

    The Main tab appears in the right panel.

  3. Click the Edit button from the Connection group.

    The Properties for >connection_name< dialog box appears.

  4. In the Connection port and Interface Type group:
    1. Select the OpenSDA Embedded Debug – USB Port option from the Interface drop-down list.
    2. Select the USB1 : OpenSDA (OpenSDA) option from the Port drop-down list.
  5. Make sure to check the Use SWD reduced pin protocol for communications checkbox from the Additional Options group.

    Note: In case the Use SWD reduced pin protocol for communications option is not enabled, the debugger throws the error, “ERR: Can not enter background mode”.
