To program the AES key into the BBR, right-click the FPGA in the Hardware window, and select Program BBR Key.
In the Program BBR Key dialog box, specify the AES key (.nky) file by typing the file name or navigating to the desired file. After specifying a valid .nky file, the AES key field automatically fills in. Click OK, to have the Hardware Manager program/load the key into the BBR.
After programming the key, program the FPGA with an encrypted bitstream that:
- was encrypted using the same AES key as was loaded into BBR.
- had BBRAM selected as the specified encryption key location.
