GUNRadio+UHD installation on USRP E200

Dear all,

I installed GNURadio+UHD on USRP E200 in Ubuntu 10.10 system by using
the build-gnuradio script Marcus offered. After installation
successfully completely, using uhd_find_devices gave the result:

– UHD Device 0

Device Address:
type: usrp2
addr: 192.168.10.2
name:
serial:

However, the result of uhd_usrp_probe leads to the net burner to allow
the firmware build is the compatible with the host code build:
Error: RuntimeError:
Please update the firmware and FPGA images for your device.
See the application notes for USRP2/N-Series for instructions.
Expected protocol compatibility number 10, but got 9:
The firmware build is not compatible with the host code build.

Then I tried: ./usrp_n2xx_net_burner.py --addr=192.168.10.2
–fw=/usr/local/share/uhd/images/usrp_n200_fw.bin to load the firmware,
which gave the success result:
USRP-N2XX found.
Flash size: 4194304
Sector size: 65536

Begin firmware write: this should take about 1 second…

Then loading the FPGA image in: ./usrp_n2xx_net_burner.py
–addr=192.168.10.2
–fpga=/usr/local/share/uhd/images/usrp_n200_fpga.bin, which also gave
the success result:
USRP-N2XX found.
Flash size: 4194304

Success.

After finishing the FPGA image and firmware loading, uhd_usrp_probe gave
the same result as before. What could be the reason here? What is done
incorrectly?

Really appreciate your help!

Thanks,
Yan

Did you try rebooting the N200?
