Zynq PL eFuse programming error

I am following UG908 (https://www.xilinx.com/support/documentation/sw_manuals/xilinx2017_3/ug908-vivado-programming-debugging.pdf) for programming the eFuse registers of a Zynq Z-7030 through Vivado 2017.3. Once I confirm my programming settings, however, I get the following console output:

ERROR: [Labtools 27-3370] Could not set Zynq target in xsdb.

I cannot find any information about this particular error. Can anyone provide any help?

Thanks!

Re: Zynq PL eFuse programming error

I suggest to manually launch XSCT from XSDK and see if the command "targets" lists the processors.

Maybe you are not booting in JTAG boot mode and for some reason the procesors are not available?

Re: Zynq PL eFuse programming error

Hello denist,

Thanks for your response. I have had success with XSCT seeing the processors in the JTAG chain. This is the output I get from XSCT

xsct% connect
tcfchan#2
xsct% Info: ARM Cortex-A9 MPCore #0 (target 2) Stopped at 0xffff4ce8 (Suspended)
xsct% Info: ARM Cortex-A9 MPCore #1 (target 3) Stopped at 0xffffff34 (Suspended)
xsct% targets
  1  APU
     2  ARM Cortex-A9 MPCore #0 (Suspended)
     3  ARM Cortex-A9 MPCore #1 (Suspended)
  4  xc7z030
  5  APU
     6  ARM Cortex-A9 MPCore #0 (Running)
     7  ARM Cortex-A9 MPCore #1 (Running)
  8  xc7z030
xsct% 

Please let me know if anything seems wrong here.

Re: Zynq PL eFuse programming error

Do you have two identical devices on the same JTAG chain?

Maybe the tool has a problem with that.

Re: Zynq PL eFuse programming error

denist,

Yes I do in fact have two identical Z-7030's in the same JTAG chain in this design. Is there documentation that confirms this as an issue? And do you know of a potential workaround?

Thanks so much for your help!

Re: Zynq PL eFuse programming error

For what it's worth, I have found this to be a very similar issue to what is discussed here https://www.xilinx.com/support/answers/58584.html

When pulling MIO2 high to boot the Zynq's in independent JTAG mode, the PL eFuse programming succeeds. I am using the 2017.3 tools, is this an issue that is/will be fixed in a future version?
