Re: [Discuss-gnuradio] Write bin to SD card

Hi Eric,

Thanks very much for your reply.

I tried to verify the bin that I programmed in the SD card using -v option. No error message and no success message either. But if I plug in the SD card to the USRP2, I still cannot get any LED on. Do you know what could cause this problem? Thanks!

Regards,
Yabo
