ARM MPS2 User Manual

A battery supplies power to part of the FPGA that stores the AES decryption key. You use this key to
enable loading of encrypted images.
Caution
The decryption key is lost when this part of the FPGA loses power. If this happens, you must return the
board to Arm for reprogramming of the decryption key.
