[Discuss-gnuradio] N210 FPGA image not compatible with the host uhd code build?

[LD Zhang]

Hello community,

There seems to be software compatibility issue between the host (ubuntu 12.04) uhd build and USRP N210 FPGA image. The Runtime errors are captured as:

------------------------------

$ uhd_usrp_probe
linux; GNU C++ version 4.6.3; Boost_104601; UHD_003.004.003-224-gc2e197c0

-- Opening a USRP2/N-Series device...
Error: RuntimeError:
Please update the firmware and FPGA images for your device.
See the application notes for USRP2/N-Series for instructions.
Expected FPGA compatibility number 10, but got 9:
The FPGA build is not compatible with the host code build.
Please run:

sudo "/usr/local/share/uhd/utils/uhd_images_downloader.py"
"/usr/local/share/uhd/utils/usrp_n2xx_net_burner.py" \
    --fpga="/usr/local/share/uhd/images/usrp_n210_r4_fpga.bin" \
    --fw="/usr/local/share/uhd/images/usrp_n210_fw.bin" \
    --addr="192.168.10.2"

----------------------------------------------------------------

So I did perform the above command shown in the output message. After downloading the image, the system claims that the FPGA write image was successful. But when I tried the "uhd_usrp_probe" command again, it still has the same error message, as if the updating did nothing to change the situation.

I did notice that when downloading the image, it was from:

Downloading images from: http://files.ettus.com/binaries/master_images/archive/uhd-images_003.004.003-205-g4896bf78.zip

But the message from the probe command returns the uhd image version as follows:

$ uhd_usrp_probe
linux; GNU C++ version 4.6.3; Boost_104601; UHD_003.004.003-224-gc2e197c0

Is it possible that the downloaded fpga images is outdated, and a correct version that matches the label 224 would work? Where is the correct FPGA image to download?

Thanks,
