Failed to set MCUboot secondary to external flash. E: Failed to open flash area ID 2 (image 0 slot 1): -2, cannot continue

I have problem placing MCUboot secondary to external flash. I have been testing using nRF9160DK. Project compiles fine but device doesn't boot after flashing the firmware.

Here is the log from serial output of the board. I get error message E: Failed to open flash area ID 2 (image 0 slot 1): -2, cannot continue at the end.

mmade I had the same issue with nrf52840 dk and finally found it to be related to 

CONFIG_NORDIC_QSPI_NOR.

It was not enabled in my project.

Hope this helps.

Thank you for the tip. I have tried to add CONFIG_NORDIC_QSPI_NOR to mcuboot.conf and prj.conf but it doesn't solve the problem.
