Hello,
my problem is that with ULINK2 and AT91SAM7 ARM controllers I get a data abort exception when single stepping my code. It comes suddenly and may be at the first or more steps (1 to about 10 I guess). I haven't noticed that before. I cannot think it came directly after I updated my MDK ARM compiler. I have tried with various source codes and different boards. I have tried with ULINK-ME where the problem seems not to exist. When I run the code without the debugger no data abort is ussued. So I ask myself is the ULINK2 defective? Can it be repaired? Is there a firware issue with the ULINK2?
Has anybody experienced a similar problem so far?
Looking forward to hear your comments.
When I think about it - it may be as you said an alignement problem. Maybe Keil have made a mistake with the introduction of the SAM3 controllers which support unaligned data access.
