All, I just received my N210 and followed the UHD manual for putting the images on their and it worked at first but then I ran into problems. I successfully got the firmware and fpga on the usrp but then uhd_find_devices fail to find it. Then I realized that I had the wrong image for my version of UHD. I tried to write firmware again but it timed out from then on. I tried to put the N210 into safe mode by holding down S2 during a power cycle but the net_burner kept timing out. Anybody have an idea what is going wrong? Here is the printout of what I did. user@ubunte:/usr/local/share/ uhd/utils$ ./usrp_n2xx_net_burner.py --ip=192.168.10.2 --fw=/home/sjohnston/Desktop/UHD-images-002.20110122035832.cd5631f-Linux/share/uhd/images/usrp_n2xx_fw.bin USRP2P found.

I bet if you watch with Wireshark you'll see the device is replying. However the checksum is just null. I'm in the same position as you.

Hey Scott and Jason, Life got a lot easier when I moved over to Ubuntu. Here's some quick notes on how was able to communicate with N210 with "uhd_find_devices". * Check out the latest and greatest version of UHD's 'next' branch. That's commit id 'f7a4861'. * I burned a new firmware and fpga image to device. I used the images available here<http://www.ettus.com/downloads/uhd_images/UHD-images-002.20110120060622.7d918c5/> . * The instructions for burning are available in the manual<http://www.ettus.com/uhd_docs/manual/html/usrp2.html#load-the-images-onto-the-on-board-flash-usrp-n-series-only> . * Finally I setup my network to use the 192.168.10.* domain. At this point, "uhd_find_devices" should work. If the network is setup incorrectly, pinging and wireshark was a great help to me.
