This reminds me of a question I have about USRP2. My understanding is the USRP2 has a Xilinx Spartan 3, which I don't think come in anything other than BGA packages. Hopefully Matt brought the JTAG lines out in case people want to deadbug a header and use standard tools. Even better would be the 0.1" holes to install a header if desired. -Jeff _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
