I'm running AS 7.0.1931 with recent Atmel Kits (7.0.122) and developing on a SAM E54 Xplained Pro board.
I used Atmel START to create the "Low Power Modes" project and imported it into Atmel Studio. It compiled without any errors.
But when I clicked on "Start Debugging and Break", it (evidently) programmed the SAM E54, but instead of breaking at main(), it opens a Disassembly window with the cursor pointing at address B9337822 with "Memory out of bounds or read error".
If the base FLASH window is to be believed, it appears that the part did not program correctly: you can see B9337822 as the start vector address.
Re-starting Atmel Studio does not solve the problem.
Cleaning and rebuilding the project does not solve the problem.
Other projects (e.g. stdioE54X, listed in the Solution Explorer above) load and execute without trouble.
Any ideas as to why this is failing and how to fix it?
