Hung Bui said:

So you saying that it works fine when you follow the link ? But not when you try to do it with external flash ? 

Yes i din't see that msg while working with internal flash

Yes, then please let us know what's the modification you made to change it from internal flash to external flash. 
Please don't point to another case because there are lots of modification and different samples there.

attached one pm_static.yml file for external flash modification . here it is.

external_flash:
  address: 0x00000
  end_address: 0x80000
  region: external_flash
  size: 0x80000

mcuboot_secondary:

  device: IS25
  end_address: 0x39000
  region: external_flash

in prj.conf file configured the spi to communicate with external flash . here it is.

In overlay file also enabled the is25 external flash  as below:

These are the modification did for external flash .

Hi Shikamaru, 
What you provided look good but could you check you have the overlay in both the application and the MCUBoot child image ? 
I have made an example here to use the mx25r64 as the external flash for MCUBoot and it worked for me. My suggestion is to try modify my example to see if you can make it work for the is25 ? 

Do you see any error log on the nRF52 ?

Yes , i have checked it ,  overlay file is there in both folder.
