I'd like to add the SAM-BA boot loader to a current project but things aren't working as I expected. I was hoping someone could offer a little explanation/guidance into what I am seeing. I am using an ATSAML21J18B chip and Atmel Studio 7. I'm following the procedures detailed in AT10840. I have created the new example project but I can't seem to make a connection via COM port and the SAM-BA gui. I have compiled the code only for USART support, according to the documentation the boot loader should reside in the first 8k of flash 0x0 - 0x2000. If I start the project with the debugger and look at the memory window or disassembly I'm seeing code all the way out to address 0x296A. I rebuilt the project to check the build output and seemingly verified this finding:
Program Memory Usage : 10612 bytes 3.9 % Full
Does anyone have any idea what may be going on here? I've read through several app notes and forum posts and have run out of ideas. Any assistance would be greatly appreciated, thanks.
