RFNoC Getting Started - FPGA Programming Error

[Fausto4n3]

Hi,

having some trouble following the RFNOC example procedure,

Getting_Started_with_RFNoC_Development

during the FPGA costum programming phasis I've got the following critical warning and error:

CRITICAL WARNING: [Project 1-486] Could not resolve non-primitive black box cell 'LvFpga_Chinch_Interface' instantiated as 'lvfpga_chinch_inst' [/home/sigint/uhd/fpga-src/usrp3/top/x300/x300.v:649]

ERROR: [DRC 23-20] Rule violation (INBB-3) Black Box Instances - Cell 'lvfpga_chinch_inst' of type 'lvfpga_chinch_inst/LvFpga_Chinch_Interface' has undefined contents and is considered a black box. The contents of this cell must be defined for opt_design to complete successfully.
INFO: [Project 1-461] DRC finished with 1 Errors

Other hardware and software information:

USRP radio: x310

OS: ubuntu 16.04

Xilinx: Vivado 2015.4

Could someone help with this?

Thank you

Fausto

Hi Fausto,

if a "make cleanall" doesn't help, could you please write an email to support@ettus.com?

This is Ettus-specific build infrastructure, and we normally don't monitor the NI Forums, I'm afraid.

Best regards,

Marcus
