JTAG Chain HPS and FPGA - Excluding HPS or FPGA via Jumpers - Cyclone V SoC

Hi guys, I want my custom board to be able to connect to both FPGA and HPS via JTAG. To avoid unnecessary cabling I thought of implementing a JTAG chain that includes both HPS and FPGA. However...

The JTAG chain is also routed tio the MICTOR connector. You may want to configure the FPGA via JTAG from the on-board USB blaster, but debug using a tool connected via the MICTOR connector. The jumpers allow you to do this. There may be other scenarios were he jumpers are useful in a development environment.

Hi Andrew

Thanks for your response.

So if HPS and FPGA are fixed in a JTAG chain can I still configure each independently?

Cheers,
