    I’m trying to get live profiling to work on a custom design based on the Nordic Semiconductor nRF52.  Due to space limitation, we could only bring out the SWCLK and SWDIO lines.  The SWO line is not connected to the debugger.

    Does live profiling require use of the SWO line?

    Hi,

    No, Live Profiling uses the regular SWD/JTAG lines and does not require any extra connections. It relies on the fact that you can read/write target memory over JTAG/SWD without stopping the target and uses a simple memory buffer for communication.
