Single-stepping just tests that something gets done.

Have you used an oscilloscope and measured the speed of the signals. The individual timing of all signals? Because whenever you move "working" code from one processor to another, your task must always be to:
1) Check that all signals can be correctly set as "on" or "off".
2) Check that all required timing are within the specifications.
3) Check that the voltages are as expected.
4) Check that rise and fall times are as expected.

Embedded development isn't just writing code and debugging. It's just as much a job that requires working with the actual electronics.
