WARP Project Forums - Wireless Open-Access Research Platform

I figured something was wrong with my drivers, so i reinstalled the hardware. Apparently, the file  xusbdfwu.sys was missing from the System32 folder in Windows. The error mentioned earlier dissapeared , only to give a newer one when updating the bitsream:

Thanks for the help.

I used the default code-- a simple copy-paste-- no changes were made whatsoever. BRAM initialization was marked.

Working.....thanks .........will save everything from now on.....lesson learnt. :)
