Here are the steps required to enable JTAG Fallback:
  1. Enable the JTAG Fallback feature of the Debug Bridge (AXI-to-BSCAN mode) master of the debug network to which you want to provide JTAG access. This step enables a BSCAN slave interface on this Debug Bridge instance.
  2. Instantiate another Debug Bridge (BSCAN Primitive mode) in the static logic partition of the platform design.
  3. Connect the BSCAN master port of the Debug Bridge (BSCAN Primitive mode) from step 2 to the BSCAN slave interface of the Debug Bridge (AXI-to-BSCAN mode) from step 1.
