Which file are you mentioning? In sample project only sample.yaml file is presented.

Could you open the build/zephyr folder and upload the partitions.yml file thats located there?

The sample is looking for an external flash, AFAIK, which it cannot find since you've stated you don't have one, right?

This is again caused by the sample looking for an external flash. Did you make any modifications to it to ensure it does not use an external flash?

I'll see if I can look closer into the sample tomorrow, but in the meanwhile please provide me with the partitioning file

Kind regards,
Andreas

For NVS sample, there is no such yml file in build/zephyr folder.

I have tried another sample for internal flash write/read/erase, get this from nordic wesite

Noted,

Unfortunately I need some more time to look closer into this. I will see if I can recreate this on a 5340dk next week. 

Kind regards,
