Zynq 7020 Production Chip, JTAG chain does not show the DAP.

Jump to solution

Hello,everyone!

I have a problem on the Zynq 7020 production chip.

 

Why JTAG chain does not show the DAP? Where ARM?

iMPAC:

Boundary-scan chain validated successfully.

I also encountered such problem on our own designed board. The solution may be to disable the "PLL Bypassed" as discussed in this link http://www.xilinx.com/support/answers/54195.html

Hi, I am having the same problem with JTAG chain not showing the DAP, did you disable the PLL by setting MIO6 high?

Thanks!
