Hi all, As per the advice given, I have started to try change the FPGA code to bypass the DDC for the USRP2. I am first trying to edit using the 30day trial for ISE v12 in Windows. I have 2 questions, 1. I fail to locate the project file from the git.
The project file is generated by a tcl script http://www.ettus.com/uhd_docs/manual/html/usrp2.html#building-firmware-and-fpga-imagesOn windows, you will need make (probably gnu make), and the xilinx xtclsh (xilinx tcl shell) in your path. I would use cygwin.
2. I was wondering if the AeMB processor directly feeds off the output of the DDC module (i_out and q_out) or it only manages the flow of data?
The microblaze manages the flow of data by acting as a packet router. In firmware/microblaze/lib/ see dbsm.*
