I've run into an issue loading a binary into flash on a SAMG55. I keep seeing this exact error pop up, but it's not something that always happens, as it depends on the final compiled code (i.e. recompiling with changes sometimes makes it go away). I've also attempted to load a problematic binary into a second board, and have the same result, so it's not a damaged byte in the flash memory. I'm stumped on this one. My current work around is to not verify the flash when programming, but it's not a final solution, and I'd really like to know why this is happening.
Any insights on this issue?
