remote upgrade and generic serial flash ip

[elaine1]

Hi,

I need to implement a system that can do a remote upgrade of a cyclone 10 lp fpga.

I need to write the images into flash with user logic inside of the cyclone 10 fpga that is connected to the generic serial flash controller.  Then I need to use a remote update to program the fpga with the image.    I have the logic in that connects to the generic serial flash controller to write the images.    I need to understand how to implement the remote update ip with this other logic.

When I build the remote update Ip it only gives me either a parameter bus or avalon bus or ASMI bus depending on how I generate the ip.   So how do I implement this?  The remote update ip does not have a bus that interfaces with the generic serial flash ip.   There is no ASMI bus to Avalon MM bridge either.  The remote update ip does not produce the spi pin outputs to the flash either.

Your help is appreciated.

Hi,
unless you implement application image verification, there's no connection between remote update and flash loader IP in your design. Respectively they can be treated as separate design modules. User interface to remote update IP is at least required to trigger reconfig, optionally to set parameters like watchdog operation. For serial flash interface, you can choose between ASMI ASMI II and generic serial flash IP.
Choice depends on used flash and intended application interface.
