Just hold down the "safe mode" button S2 when booting. The image you're loading is probably bootstrapping the production FPGA image out of Flash. --n On Tue, Oct 25, 2011 at 10:15 AM, Ian Buckley wrote: > I've only done a little FPGA work on the N210 so this is a bit of a guess, > Nick or Josh

Re: [Discuss-gnuradio] .bit file not loading on usrp n210

I've only done a little FPGA work on the N210 so this is a bit of a guess, Nick or Josh can answer better, but I would imagine you probably need to understand how the FPGA image "bootstraps". The N210 stores 2 FPGA images so that there is a safe image to restore from if you upload a bad image. T

Everything except for the USRP1 has dual halfbands for both TX and RX, including the B100. One of the big advantages of the B100 over the USRP1 is that it uses nearly all the same FPGA code as the USRP2, N2x0, and E1x0, so they all support the same DSP features. USRP1 has a smaller FPGA from a di
