Hi,
I am using nRf9160dk with mcuboot secondary image on external flash base on AZURE_FOTA example, ncs 2.0.2.
Found the bootloader cannot runs primary image.
So, I need advice on how to set up the mcuboot secondary with SPI flash.
*** Booting Zephyr OS build v3.0.99-ncs1-1 *** I: Starting bootloader W: Failed reading sectors; BOOT_MAX_IMG_SECTORS=128 - too small? E: Image in the primary slot is not valid! E: Unable to find bootable image
Checked the partition with west build -t partition_manager_report .
