Trace Port

The section Trace Port controls the communication channel used for trace operations.

Serial Wire Output – UART/NRZ is the only Trace Port that ULINK2 supports. Make sure to select SW for Port in the dialog ULINK USB-JTAG/SWD Adapter.

SWO Clock Prescaler defines the communication speed when using Serial Wire debugging mode. Values from 1 to 8192 are allowed (that result in any clock value up to 1.25 MHz or the discrete values 1.875 MHz/3.75 MHz).

Autodetect configures the prescaler automatically for the highest possible SWO Clock. It will be calculated using the given Trace or Core Clock setting.

SWO Clock displays the calculated SWO Clock rate, determined by the Trace or Core Clock and the SWO Clock Prescaler value.

Detected errors are displayed below the field SWO Clock.
