JTAG chain debug with 3rd party devices - what mode are they in?
I am designing a new board and our current plan is to have our ARM processor and Kintex on the same chain. I understand it is possible to use Vivado Logic Analyzer to do debug on the Kintex by specifying the ID code and IR length etc when connecting to the hardware.
Ok, that's fine. Could anyone tell me what JTAG mode (e.g. BYPASS) the 3rd party device is left in whilst I use the logic analyser to do debug n the kintex? I will sometimes need to debug the Kintex with software running on the ARM. Will this be possible or will the JTAG chain mess this up?
