Hello, I am trying to make use of the remote configuration IP core for the Cyclone V E. I have gotten the image to properly jump to a different configuration image start. My "factory image" is at 0x000000, while my "application image" is at 0x200000. After I erase and write in a new configuration image at 0x200000 I get a CRC error. Does the CRC get calculated off of the entire configuration file, i.e. when I made the original JIC file, where I had the factory image and application image together? Basically, my central question is, is it possible to partially erase only the old application image, place on a new one, and boot from the old factory image? It seems like that is the purpose of the remote configuration IP... but maybe I'm misunderstanding something?

Hi TMayd,
In order to get more understanding about this issue, may I know which flash device you are using? (eg, EPCQ,EPCQ-A, etc2)
Thanks

Hi TMayd,
Thank you for your reply.
"Does the CRC get calculated off of the entire configuration file"
Yes, CRC calculated from the configuration file.
"is it possible to partially erase only the old application image, place on a new one, and boot from the old factory image?"
Yes, it is possible to do so. You need to use the register Map to control your RSU design. You may refer to the following RSU reference design. You may see how we control the RSU using the Register Map.
Let me know if you have any further queries.
Thanks.
