Thanks Josh. Found that line of code.
Following your advice, I have tried both methods you mentioned and have run into problems for both. For the first one, I have followed the install instructions for microblaze toolkit given on the gnuradio wiki and after setting the path, I tried to configure. usrp2-firwmare failed and the reason that wwas showned was that they failed to detect mb tools. I then tried to install UHD and I managed to copy the firmware and FPGA configuration into the card and I managed to verify by pinging the USRP2. I am however unable to run any of the cpp files even as root as permission is denied. I am asking for help if there is anyone who has a modified binary firmware file compiled for the gnuradio version that I can have. I also would like to ask for help to compile a modified FPGA image.
