Problem updating firmware on SD card

GNU Radio
1

Hello,

I am trying to update the firmware on the SD card per the instructions
here:

http://www.mathworks.com/support/solutions/en/data/1-CUN7JZ/?solution=1-CUN7JZ

I’ve downloaded all the firmware to my PC, and put the SD card from the
USRP2 into my PC. I am using Windows XP. My PC tells me its not
formatted so I can’t see what is on it. I did not reformat it as windows
suggested. However, when I run the usrp2_card_burner_gui.py, it does not
recognize the device when it scans for it. I tried ‘rescan for devices’,
but that did not work. I then manually entered the path to the SD card
in the Raw Device and clicked ‘Burn SD Card’. However, this gave me
various errors that there was not a file system: Error opening output
file 1005.

Do I need to format the SD card? I am hesitant to do so. Is there
something I am doing wrong?

Thanks for any help.

If it helps to some degree, this is what it is supposed to look like:

You dont need to format the card, does it at least show up as a drive
letter in my computer?

I have seen the app work on XP and 7, and been informed of vista. I
dont know how to make windows behave. Its such a headache.

Do me a favor and download dd for windows, and run dd.exe --list with
your card in and post the output. chrysocome.net - dd for windows

Since this is the gnuradio mailing list. I am compelled to list the
following open source alternatives:
gnuradio + gnuradio companion for graphical creation of a realtime or
simulation block diagrams
python + scipy for plots, graphs, scripting, vector and matrix
arithmetic http://www.scipy.org/Plotting_Tutorial

Hi Josh,

Thanks a lot for the screen cap. Windows was recognizing the SD card as
D:, but from your screen cap, I tried entering it as \.\D:, and the
burn was successful.

Hello,

maybe you can help me. I am trying to update the firmware too. I am
using Windows XP SP3 and the same instructions from Mathworks, but
everytime when I try to launch the usrp2_card_burner_gui.py I got the
following error message:

File “usrp2_card_burner_gui.py”, line1

SyntaxError: invalid syntax

Thanks for any help.
