You could confirm the compile address of the code going into DDR, you could disassemble it with something like objdump, and walk through it.

In order to simplify the addressing, all the masters have at911sam9g45 same decodings I must admit SAM-BA has at91sam9gg45 into rather a cluster over the years, I’d be a lot more temped to inject code with something like Keil and tinker with bringing up the hardware that way.
