Hi,
I am receiving the same error this guy was: "https://devzone.nordicsemi.com/f/nordic-q-a/28724/sdk-for-mesh-v1-0-0-with-ses-invalid-ascii-encoded-byte-line-1" and am posting this question because the previous ticket was not closed (doesn't have a definite answer.)
I checked my RAM and FLASH start addresses like the comments in ^ suggested... I am sure my configurations and paths are in place. I am using SDK 15.2 (when I build/run my project in SDK 15.3 it gives same error), and embedded studio.
What does this error mean and how do I resolve it?

Thank you
