20.2.2.3.6 Misc

Use the Misc tab to enable the following options:

  • Trace functionality
  • JTAG (Debug) functionality
  • Interrupts to/from MSS
  • Configuring GPIO Interrupt Register
  • Exposing Boot Status ports
  • Exposing feedback ports to fabric
Figure 20-38. Misc Tab

For more information, see PolarFire SoC FPGA MSS Technical Reference Manual .

By default, these options are marked as Unused. When any of the options are enabled, the corresponding ports are exposed on the MSS block (see the following figure).

Boot Status: When Expose Boot Status ports option is selected, the ports BOOT_FAIL_CLEAR_F2M and BOOT_FAIL_ERROR_M2F are exposed as shown in the following figure.

MSS Feedback and Debug Ports: This option is only available for production devices. If selected, a group of MSS_FEEDBACK_DEBUG ports are exposed as shown in the following figure.

Important: In a Libero project, when System Controller Suspend Mode is enabled (Project > Project Settings > Device settings), the PFSOC_SCSM macro must be instantiated in the user design and the REBOOT_REQUESTED_M2F pin of MSS must be connected to the SC_WAKE pin of PFSOC_SCSM macro to wake up the system controller temporarily so it can reboot the MSS during normal operation.
