I copied the latest txrx.bin and u3_rev3.bin on a new 256MB SD-card. Then I verified and made sure it is properly copied. Still no success. LEDs don't turn on. I also tried some of the older firmware/fpga. Same results!
When I use the original SD-card, the LEDs turn on properly, but for some reason the USRP2 seems to be suppressing my ethernet interface. The ethernet interface on my laptop looks dead; its light is off and it even won't send any packets out upon each "find_usrps" call. Whereas when I use the newly programmed SD card, or when there is no SD-card in the USRP2, the ethernet interface on laptop is alive and at least it properly sends ethernet packets out upon each call to "fins_usrps." Very strange situation! Any help is highly appreciated. Omid On Fri, Feb 12, 2010 at 12:56 PM, Omid F <omid.fat...@gmail.com> wrote: > Thanks for your response.
