JTAG Header for HPS and FPGA

Hello, I would like to use one JTAG header for the FPGA side and one header for the HPS side of the side will this be a problem? I thought this would make this less complex. My co-worker daisy-chain...

Dave,

Hi, thank you for responding to my post. I am new to the ARM processor so please excuse my questions. My first one is, "to debug the HPS does it require a special programmer that has a Mictor connector?" Also, when you are bebugging the system it would then appear that you need both programmers connected one for the HPS and one for the FPGA. Is the software able to debug both HPS and FPGA at the same time, I thought that would be done through a single JTAG connection. I have been looking over the SX Cyclone Deve Kit (5CSXFC6D6F31C8NES) and I do see that they are using a Mictor Connector so I will have to do some more reading on this connector. Although it is a little difficult to see the JTAG flow for the FPGA and the HPS because of the switches.

If you do use a single JTAG for the HPS and FPGA are there any limitations? I ask because that is what my co-worker did and his board is now in PCB layout.

Thanks again,

joe
