CFM0 Overlaps with Configuration Data (Error 20646 Quartus Prime)

Hi, We are using 10M25 for the design of our PFR enabled FPGA code for a server motherboard. Here we have partitioned CFM0 for recovery image and CFM1 for the active image. We had a reference design...

    Hi,
    obviously, userdata start addresses of 0x41000 and 0x83000 are not suitable for 10m25 flash layout. If you want to keep the distance from CFM1 and CFM0 end address (-0x9000) , they should be changed to 0x5b000 and 0xb7000.

    P.S.: I don't work with NIOS II and am not aware of the relation between start adresses and vectors shown in post #1 for 10m16. But basically everything should be relocated according to increased CFM1 and CFM0 flash size.

    Regards
