Are you using the Rev4 version of the FPGA image? That might perhaps
seem like a question not worth asking, but the FPGA images for
Rev4 N210 have a slight difference, because the ADC-to-FPGA hardware
interface is slightly different in Rev4 N210 hardware than in
previous revs. So if you're using an FPGA image for R2/R3, it will
produce just noise.
