We're using Arria 10 with EPCQ device, and looking for solutions to protect the EPCQ content.
The EPCQ is used for holding both the configuration bitstream and also other data.
Configuration bitstream can be encrypted using the Design secure feature. Is there an option to use the same key for encrypting the other data that we store on the EPCQ?
Thank you for your reply.
I didn't mean a new design file, but other data that we store on the flash.
During operation, nios read/write data from/to the flash. Is there an option to encrypt this data using the existing mechanism that deals with flash encryption (Design secure feature), or we need to use another encryption block to be in the middle between nios and flash?
