Program FPGA failed when FMC (DC1532A-L) plugged into FMC-Carrier Card

nowksru

Hello,

I am trying to program the MicroZed through the FMC-Carrier Card via JTAG, while the FMC module DC1532A-L (Linear Technology) is plugged in the Carrier Card. But when I click on the Program FPGA button in Xilinx SDK (2017.4) I get the following error message:

"Could not find FPGA device on the board for connection 'Local'.

Troubleshooting hints:
1. Check whether board is connected to system properly.
1. In case of zynq board, check whether Digilent/Xilinx cable switch settings are correct.
1. If you are using Xilinx Platform Cable USB, ensure that status LED is green.
Program FPGA failed"

If I unplug the FMC module from the Carrier Card, SDK runs the programming without a problem --> board is connected to system properly and status LED is green in both cases (FMC module plugged in & unplugged). I guess the FMC module is somehow interfering with the JTAG pins?
 

I don't know if it is important, but my application is just reading registers on the FMC module through SPI.

    Hi Urs, 

    I see what you are saying now. Thanks for clarifying. Please make sure the VADJ is set correctly on your Carrier Card to account for the FMC's required IO voltage.

    Hi Josh,

    I already checked the VADJ and set it to 1V8 as the module expects 1.8V. I also checked my constraints in Vivado, which I set to 1.8V. But I still don't see how a plugged in module can block the programming sequence or even the detection of the MicroZed.

    By the way, this is the error (from the TCL console) I get from Vivado Hardware Manager when trying to program the Microzed on the FMC-CC:

    open_hw_target
INFO: [Labtoolstcl 44-466] Opening hw_target localhost:3121/xilinx_tcf/Digilent/210299A56456
ERROR: [Labtools 27-2269] No devices detected on target localhost:3121/xilinx_tcf/Digilent/210299A56456.
Check cable connectivity and that the target board is powered up then
use the disconnect_hw_server and connect_hw_server to re-register this hardware target.
ERROR: [Common 17-39] 'open_hw_target' failed due to earlier errors.
