Hi Stephane,

Thank you very much for your comment. It's my fault. I forgot to add a line to the fpga/usrp2/sdr_lib/Makefile.srcs. I fixed this error. To successfully compile the FPGA project, you will need to update your local repository from github.

FPGA compilation error
======================

Assuming this is because of a missing/out-of-date FPGA image, I tried to
compile the latest (git) FPGA firmware:

cd UHD-Fairwaves/fpga/usrp2/top/N2x0/ ; make clean ; make UmTRXv2

but got the following error:

ERROR:HDLCompiler:1654 - "/home/stephane/Public/src/umtrx/UHD-Fairwaves/fpga/usrp2/top/N2x0/u2plus_core.v" Line 734: Instantiating <rx_frontend_sw> from unknown module <frontend_sw>

A quick `git blame` points to some changes in January but I wouldn't
know where to start fixing this (or maybe this is an issue with my
environemnt and not the code). In case this is the environemnt, I'm using
ISE 14.4 on Linux/amd64

Regards,
Andrew Karpenkov
