Hi all
In development with nRF91 and my application need to using an external flash memory to store the firmware and I try to follow the example this link below.
But I found when I enable to use external flash memory to store firmware slot 1. The bootloader can't enter to use the firmare in slot 0 on flash memory of nRF91.
I'm not sure. What's happened? Every time, My board has to restart.

Base on:
1. SDK version ncs 2.0
2. HW PCA10090 V.1.0.0
My source code for test.
