Bitstream and IAP Image Authentication System Services

For security and reliability reasons, the programming bitstream must be authenticated and validated before the device is programmed. Successful authentication of the bitstream prevents auto recovery. While the authentication is in progress, the fabric user logic in RT PolarFire FPGA continues to operate normally, though without access to SPI flash and system services. Before the device is programmed using auto update or IAP, the user application can run the authentication system service.

Note: If the bitstream authentication system service is initiated while a new bitstream is being loaded through the JTAG interface, the system service takes precedence, and the JTAG operation fails.
