Here are the steps required to enable JTAG Fallback:
- 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.
- Instantiate another Debug Bridge (BSCAN Primitive mode) in the static logic partition of the platform design.
- 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.
