Relationship between EPCS controller and Remoteupdate Megafunction

Hi there,

I am getting confused by the relationship between the EPCS controller and the remote update megafunction:

Does the remote update megafunction contains a EPCS controller in it to interface with EPCS flash? Or Remote update megafunction is the master to the EPCS controller?:confused:

Thanks,

Hua

    - There is probably a RSU<->avalon bridge for the NIOS but I do not know its name

    - EPCS controller allows communication with the EPCS using the Nios.

    - ALTRSU_UPDATE megafunction allows your custom logic to control the booting of the FPGA

    - ALTASMI_PARALLEL megafunction allows your custom logic to communicate with the EPCS device

    So if you have a NIOS use the first two. If you donßt, use the last two.
