SW Device

The SW Device section displays one or more debug targets connected through the Serial Wire interface. The IDCODE and Device Name are displayed automatically for each device.

Target Driver Setup - SW Device

  • AP specifies the identifier of the Access Port in multi-core devices with a single Debug Port.
    • The AP value range is 0 to 255.
    • For single core devices, set AP to 0 (default).
    • For a multi-core device, core 0 is expected to have AP=0 and core 1 AP=1. However, the port identifiers are specified by the device manufacturer.

    If AP contains an invalid identifier, the error message "Invalid ROM Table" is shown whenever a debuging session is started.


  • This part of the screen changes with the value of the field Port. For JTAG refer to the description in JTAG Device Chain.
