Re: [Discuss-gnuradio] USRP2 FPGA Compiling
Works fine for everyone else, but we are using ISE 12.1. It shouldn't be different, though. The most likely problem is programming the SD card incorrectly.

First I wanted to compile the latest fpga code and verify its operation. I downloaded (git) the latest fpga code. I have ISE 12.2 running on a WINXP_Pro SP2 PC. I modified the makefiles to work with the latest cygwin. Actually I invoke "make proj" to create the ISE project, and then use the ISE tool in Windows to perform the compile. I set the "Design Goal" to "Timng Performance" and the fpga build completes successfully with no errors and all timing constraints met! I generate the programming file, u2_rev3.bin, and put it on the SD card. The problem is that the LEDs on the USRP2 do not behave correctly. After power-on, the F-LED lights, and that's all. This says that the fpga is configured, but the follow-on all-LED blink and D-LED did not happen. The ISE 12.2 that I am using is a full version that I downloaded, and I have a 30-day free trial license. All indications of the ISE tool seem to be ok for a successful fpga build. The .bin file size is the same as the original. As I stated before, there were no build errors, but many Warnings, related to port size mismatch, registers with IOB=TRUE, that are not associated with IOBs, unused module inputs, RAM_D inputs never assigned. Actually, in the USRP2 schematic, PIN V15 is "reset_fpga" and in the u2_rev3.ucf file, PIN V15 is "PHY_CLK". So there is a discrepency. I will check the other pins. Any help is appreciated. Also if anyone can email to me their successful build warning report(s), this can help. I'm sorry for the long posting.
