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.

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
