The availability of P‑JTAG, SWD, 16‑bit trace, and 4‑bit trace, depends on the design that you
implement in the FPGA.
•
The Debug USB connector supports remote USB access to the MCC to enable remote reboot, remote
reset, and remote shutdown.
Debug over USB
Debug over USB supports:
•
Four UARTs.
•
MCC debug.
•
CMSIS‑DAP.
The following figure shows the architecture of the debug over USB system.

The four user serial ports on the Kintex XCKU115 FPGA indicate the status of the system
during boot time. After the system has booted, they are used for debug or status information.
The four serial ports are concentrated into a USB‑serial interface that connects to a four port
hub, that is connected to the USB connector. The hub enables the four FPGA serial ports, the
MCC USBDBG port, and the CMSIS‑DAP controller to share the USB debug connector.
The CMSIS‑DAP interface in the FPGA enables debug over USB to the FPGA CoreSight
components using the dedicated Arm CMSIS‑DAP controller.
The MPS3 board does not require software drivers for Windows 7 or later versions of Windows.
