I am using a SAML21 chip that doesn't have the built in SAM-BA Rom. After quite a bit of work I have modified the example SAM-BA project to work with my design. I'm now wondering if there is a way to build the boot loader code and my application code into a single elf so I only have to program the device once during production. I hoped that importing both projects into a single solution (Atmel Studio 7) might do the trick but it just builds each one individually. I'm stumped and haven't found much info regarding what I am trying to achieve. Any help or suggestions would be appreciated.
