It might be the same race condition as the query gpsdo sensors app. The
USRP is told to sync at the next PPS edge, but things may be done before
this event occurs.
Can you try adding a time.sleep(1) after the usrp source object is
created in the flow graph? Let me know if that works and we can find a
more polished way to handle this.

Hi Mike,
Actually this is how it is happening:
1) When I type targetinstaller in the matlab command prompt, it opens the
"Mathworks Access" page and displays in the targetinstaller window that " If
you
have submitted the form, continue the installation by clicking next.
If you have not already done so, log in and submit the form in the web browser.
Then return here and continue the installation."
In this window where the above message is displayed, there are "back", "cancel"
and "Help" buttons at the bottom right of the window but the Next button is not
accessible.
2) A new window(https://www.mathworks.com/programs/usrp/index.html) in the
meantime has appeared where a form is displayed and it is required to be
filled.
After clicking the submit button at the bottom left of the current window, the
user is directed to a webpage which has the download support packages for
MATLAB
R2012a, 2011b,2011a. As far as R2012b is concerned it is just mentioned there
that targetinstaller automatically installs the required drivers for USRP
support package. No UHD or USRP support version for 2012b is mentioned or
listed
there. Moreover, no procedure is mentioned about how to manually download and
install the UHD and support package for 2012b.
3) However, the targetinstaller window in 1) still does not display the "Next"
button at the bottom right corner of the window.
Therefore, there seems to be no way of accessing the required support package
for MATLAB 2012b.
Please help.
Sincerely,
Jayanta

Sorry guys. Its looks like there is an unconstrained path. Can you try
this fpga image in place of the one on your system in
/usr/share/uhd/images (this is where opkg puts it)

Hi Jayanta,
Thanks for the detailed explanation. Our web team is working now on a
long-term solution to this issue, but you can use the following workaround now:
Once you log in to your MathWorks account and fill out the survey, a
confirmation page comes up with a URL starting with
'https://www.mathworks.com/programs/usrp/confirmation.html?confirmation_page'.
You should change 'https://' to 'http://', then refresh the page. At that
point, the page should disappear and the installer's 'Next' button should be
clickable. The installation should proceed normally after that.
Let me know if this solves the problem --
Best,
Mike

Hi Josh,
I replaced the file and the problem still remained. However, it seemed to
take a bit longer before the sequence errors kicked in.
Thanks,
Ken
