NVS with external flash partition problem in non secure application

[fcollado]

Hello, 

I'm trying to run the NVS example on the NRF9160DK rev 1.1.3  with the on-board MX25R6435F external flash memory.

The sample runs OK as nrf9160dk/nrf9160 but the partitioning seems to have problems with nrf9160dk/nrf9160/ns mode.

I modified the NVS_PARTITION  macro to match with my external flash partition.

#define NVS_PARTITION           sensor_data_ex_partition

I'm trying to run it without Partition Manager because I can't make it work with  an external flash aswell.

Thanks in advance.

 

This is the error:
