MicroZed JTAG Issue

100glennholt
100glennholt over 6 years ago

I'm using Vivado 2018.1 and a Rev. F07 microZed board to try and walk through the Zed Chronicles tutorials.  I'm stuck on the "Hello World," unfortunately, as I can't get XSDK to recognize the PS. 

I'm using a Digilent SMT2 JTAG cable, and when I run Adept I can see both devices.  In the Vivado Hardware Manager, however, I see only the 7Z020, not the DAP, and in XSDK when I try to select the PS Device in the Run Configuration there are none found (the correct cable is displayed, however).  JP1-3 are set correctly for cascaded JTAG.

I also get an "FPGA initialization error" if I try to re-program the FPGA (PL), and it requires a board power cycle before I can do so (I don't know if this muddies the water or not).

Any help would be much appreciated.

    Hello Glenn,

    Please send me a link to the tutorial you are referencing.

    Please make sure your board is in JTAG Boot.

    So what your saying is you can program the PL but not initialize any application?

    Josh,

    I'm working through the tutorials here:

       http://zedboard.org/content/microzed-chronicles

    It's tutorial #4 where I hit a snag:

       https://forums.xilinx.com/t5/Xcell-Daily-Blog/Running-your-programs-on-the-MicroZed-Adam-Taylor-s-MicroZed/ba-p/372735

    Yes, the 3 jumpers are in JTAG position (all 1-2).

    Exactly, I can program the PL from the Hardware Manager or XSDK, but the PS doesn't show up on the JTAG chain in the run/debug configuration in XSDK.

    Is it also odd that once the PL is programmed I have to power-cycle the board to re-program it (otherwise I get an FPGA initialization error)?

    Thanks so much.

       -Glenn

    Hi Glenn,

    Is this a new MicroZed or one that has been in use for a while? 

    I typically do not need to power cycle my board to reporgram the fpga, however that is dependant on the cable being used. I typically use a HS3 cable for my testing.

    Josh,

    Well, you hit it right on the head!  I grew frustrated enough to purchase an HS3 and that did the trick.  

    Thanks for your help!
