Re: [Discuss-gnuradio] Errors when building E310 fpga

Hi Peter,

I'm cross-posting this to address@hidden. I think this might be a discussion that fits in there better – you might want to sign up for that list, too [1]!

this looks like a Xilinx/Vivado bug, and Ettus can't do much about these :(

Anyway, could you try whether this works with the free Vivado version you can use for the E310, when running Vivado on Linux? I know several people who use separate Linux VMs just to run the Xilinx tools.

Best regards,
Marcus

Hi all

Based on the instructions in the following link:

http://files.ettus.com/manual/md_usrp3_build_instructions.html

I downloaded fpga source code for E310 and attempted to build FPGA image in cygwin environment

The fpga source code is downloaded from 

https://github.com/EttusResearch/fpga/tree/master/usrp3

After tens of minutes, the building procedure was ended with some errors which are listed in the following lines. But I am not sure what these error really means and how to avoid them. Any suggestions are really appreciate. Cheers!
