I sent the follwing to discuss-gnuradio-list -- but it has never been published.. so I will try it here: After compiling Gnuradio 3.5.3, I got errors (seg faults) and other indication to upgrade the very old uhd and fpga firmware software for USRP N200 r2. I got the images 003.004.000 and uhd source. I compiled and installed the source on ubuntu 11.10 every step as expected from the building guides. But trying to update the firmware-fpga fails After powerdown und hold S2, the N200 did work with the follwing output -------------------8<------------------ > ./usrp_n2xx_net_burner.py --addr=192.168.10.2 --fw=uhd-images_003.004.000-release/share/uhd/images/usrp_n200_fw.bin > USRP-N2XX found. > Flash size: 4194304 > Sector size: 65536 > > Begin firmware write: this should take about 1 second... > Erasing 31744 bytes at 3145728 > Writing image > Verifying data > Read back 16383 bytes > Success. > Time elapsed: 1.149688 seconds > > ./usrp_n2xx_net_burner.py --addr=192.168.10.2 --fpga=uhd-images_003.004.000-release/share/uhd/images/usrp_n200_r2_fpga.bin > > > USRP-N2XX found. > Flash size: 4194304 > Sector size: 65536 > > Begin FPGA write: this should take about 1 minute... > Erasing 1572864 bytes at 1572864 > Traceback (most recent call last): > File "./usrp_n2xx_net_burner.py", line 522, in <module> > else: burner.burn_fw(fw=options.fw, fpga=options.fpga, reset=options.reset, safe=options.overwrite_safe, check_rev=not options.dont_check_rev) > File "./usrp_n2xx_net_burner.py", line 310, in burn_fw > self.erase_image(image_location, FPGA_IMAGE_SIZE_BYTES) > File "./usrp_n2xx_net_burner.py", line 452, in erase_image > in_pkt = self.send_and_recv(out_pkt) > File "./usrp_n2xx_net_burner.py", line 245, in send_and_recv > return self._sock.recv(UDP_MAX_XFER_BYTES) > socket.timeout: timed out -------------------8<------------------ this leaves the system without the expeceted functionality help is very welcome to get the system working again thanks in advance Michael Hartje -- Prof. Dr.-Ing.

Can you try this with a different PC or ethernet card? Does the problem follow? -josh
