[Discuss-gnuradio] Problem updating firmware on SD card

[Sam Keene]

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.
