Hi all, We have a system which must be updated remotely by a CPU. I'm able to reprogram the CFM through SPI by the mean of the MAX10 On-chip Flash IP and a SPI to Avalon-MM bridge (I creat...

Hi Johan.

I know this has been some time. I think you need to have 2 separate designs. design 1 for CFM0 . Design 2 for CFM1 & 2. ( set configuration to dual compressed image ). Only then you can generate the dual compressed pof.

Design 1 and Design 2 are 2 distinct designs, but from system point of view you can have common interface on both designs so that the MCU will see it as "single" design.

DUAL CONFIGURATION IP is pretty small ( less than 100 LE I think ). Should be able to fit into spare LE resources ( unless your are using 100% of LE)

In term of switching from CFM0 to CFM1/2 , you do not necessarily use CONFIG_SEL pin. You can use DUAL_BOOT IP /Dual Configuration IP core user interface to "launch " the app from any CFM ( can be made MCU controlled )

I agree that documentation on RSU and Dual Boot are a bit challenging, but if you look deep enough, you will find the info that you want.
