I downloaded USRP2 fpga code from
https://github.com/EttusResearch/usrp-fpga-mirror. And I rebuild the
code by using : make bin under u2_rev3 folder.
I manage to get u2_rev3.bin file.
And I downloaded firmware, “Raw Ethernet, No WBX or XCVR” from
I flashed them into SD card using flashtool command as advised on ettus
website. But I only see “F” led light up. What could be the problem?
