Dear USRP-Users Group,
I installed UHD 4.7 on an Ubuntu MiniPC following the online instructions.
It seems to be working OK, so I tried updating the firmware for an N200
that I picked up as a test vehicle for my set of new N320s. I ran into a
bug that I have not found an answer to, as seen in the following Terminal
script with UHD commands shown in *BOLD TYPE*:
drscott@Ubuntu:~/workarea/uhd/host/utils$ *uhd_find_devices*
[INFO] [UHD] linux; GNU C++ version 11.4.0; Boost_107400;
UHD_4.7.0.0-0-ga5ed1872

-- UHD Device 0

drscott@Ubuntu:~/workarea/uhd/host/utils$ *uhd_usrp_probe*

[INFO] [USRP2] 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 11, but got 9:
The FPGA build is not compatible with the host code build.
Please run:
"/usr/local/lib/uhd/utils/uhd_images_downloader.py"

[ERROR] *Invalid permissions to write images destination*
drscott@Ubuntu:~/workarea/uhd/host/utils$
UHD on Ubuntu is able to find the N200, and is able to probe the N200 with
the second UHD command. However, the third command is
*/usr/local/lib/uhd/utils/uhd_images_downloader.py*, which produces the
following *ERROR MESSAGE* - *Invalid permissions to write images
destination*. The N200 was not booted in SAFE MODE, so it should be
available for firmware updates.
I have been unable to locate any information online for how to eliminate
this problem so I can write firmware updates to the N200. Is a document
available for fixing this problem? If not, can you tell me how to fix this
firmware update problem on the N200?
Thanks in advance for your assistance with fixing this problem.
Respectfully,
Scott
