encrypted pages in active serial flash

hello

i have two pages in active serial flash in stratix 5. page 0 first load and then switch to page 1 with the remote update block.

Is it possible to use not encrypted page 0 and encrypted page 1 or both pages should be encrypted or not encrypted?

Thanks

    Sorry you cant. Once key is programmed, you will need to use encrypted bitstream for both.

      hello

      i am not tampering my configurtion file - Does it enable the use of non encrypted bitstream?

      should i use only encrypted bitstream?

    Yes, you can use unencrypted bitstream for it. But once the key is programmed, you must use encrypted bitstream.

      Hello

      as i understand in case i am not tampering my configurtion file then i can use unencrypted bitstream even key is programed. in this case only encrypted bitstream with wrong key can not be programed - is it true?

      in case it is true then what is the answer to my first question?

      Thanks Gilad
