In my experience, a successful FX2 load followed by a failed FPGA load is often due to poor USB physical integrity, such as a cable, connector, or hub. I know it sounds formulaic, but for whatever reason, I've encountered this with the USRP on multiple occasions, where replacing the cable with a different one, ensuring that has the 2.0 compliance logo on it, fixes it. YMMV, of course. (Even more often it is due to not having a 2.0 controller, but you've ruled that out already.) -Johnathan _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
