Use Qsys subsystem generate bsp error

I put some slow speed component to a subsystem inculde EPCS controller,and the reset vector point to EPCS.when i genertate bsp there is an error:

SEVERE: .entry section mapping not created because reset memory region not located at base address: 0xffffffffffffffff

when auto generation,there is no reset region in Linker Memory Regions, no entry section in Linker Section Mappings generated,so i create it menually,but the error is still there.

    I had this error with output like: 

    SEVERE: .entry section mapping not created because reset memory region 
not located at base address 0xffffffffffffffff.

    then I checked:
    https://embdev.net/topic/248933

    Had the same problem, sovled it by :

- in QSYS->System Contents , right click your Nios cpu -> Edit...
- in the tab "Core NiosII", check if "reset vector memory" points to a 
memory module and not e.g. jtag etc.
- same with "exception vector memory"
- after correction : QSYS->Generation->Generate

    And finally, I've set the proper Reset Vector Memory (on my RAM.s1 connected to NIOSII) and Exception Vector the same way. I had no "Core NiosII" tab in 18.1 version.
