Site location is not valid

reifschneider

Hi,

unfortunateley I have a persistent problem loading a design to my zedboard.

The implementation tool says "[Vivado 12-1411] Cannot set LOC property of ports, Site location is not valid ["C:/rfs/IBDR/ModulesAndIPCores/IntrinsicSecureCryptomodule/HardRSA_ZedBoard/TopModule.xdc":150]".

The Pin is set correctly:

set_property PACKAGE_PIN D11 [get_ports USART_RXD]

and I can assign it properly in the VIVADO pin assignment project.

Subsequently, the following bitstream fails because of missing LOC properties. Only 2 pins are affected, 33 other pins do not cause any trouble.

I tried many things including deleting the synth directories (as proposed in this forum) but nothing helps.

Any idea to get rid of this problem??

    Hello Reifschneider,

    First off, I would like you to post this question over at the digilent forum since they are the main point of contact for education support.

    https://forum.digilentinc.com/

    In the mean time I can off you some assistance. Is this your first time using the ZedBoard? If so, did you install the Cypess USB to UART drive? You also state above that the Pin is set correctly. What do you mean by that? What are you trying to boot from, JTAG/QSPI/SD Card? Are your Jumpers set correctly?

    If you are new to Zynq Developemtn I suggest you go through our Hardware and Software Development Speedways we offer. You can find them at : http://zedboard.com/support/trainings-and-videos

    Hello Josh,

    thanks for your assistance.

    Yes, it is the first time I use ZedBoard. But I am a professor for digital electronics / informatics since many years and have rich experience in that field.

    I do not use any OS or even the PS.

    I have a bare glue logic design that runs perfectly on a SPARTAN 3 board. It includes, besides hardware giant modules for basic mathematical operations on large numbers (virtually unlimited places controlled by VHDL parameters, currently limited to 1024 binary places by limited hardware resources of SPARTAN) , a Picoblaze Processor which has been extended to more memory/registers/bit width/instructions (like MUL and DIV). In addition, a USART (VHDL module, self designed) which allows communication with the board via RS232.

    We can send commands to the board via RS232 (a command interpreter runs on the PicoBlaze code) and exchange Data with C programs that run on standard PCs.

    Now I wanted to implement this design on ZedBoard to get rid of the hardware limitations. Therefore I need to connect the RX / TX lines of the implemented USART to the Pins D11 and C14 of the XC7Z020-CLG484. These lines, in turn, are connected to the TXS0102DQE device on the ZedBoard, (Pins 2/3), directly.

    The Pins are set correctly, I mean the lines

    set_property PACKAGE_PIN D11 [get_ports USART_RXD]
    set_property PACKAGE_PIN C14 [get_ports USART_TXD]

    in the .xdc file clearly define where to connect these pins. In addition, I can place these pins correctly in the pin assignment project.

    As I stated before, I do not boot at all because I only have glue logic.

    The pins mentioned are the only ones that result in the error message "Site location is not valid". All other pins like the ones for the OLED control are processed properly (I do control the OLED directly using PicoBlaze code).

    If I remove the pin definitions for D11 / C14, the design is processed correctly and the final hardware runs perfectly, including OLED and LED control.

    Regards

    Norbert
