Unexpectedly debugging stops at the same point

[Anonymous]

Someone please advice me.
When debugging target board(CY8C29466-24PXI) with ICE cube ( using Designer 5.4 ), unexpectedly debugging stops at the same point every time with yellow highlight.
But I don't set break point there. The point is 'reti' in PSoCGPIOINT.asm.
I continue execution from there, and execution stops at the same point again.
And then, after I remove the pod from board, I have debugged with only the pod. But same result.
I can't debug. Is ICE cube broken?

The issue seems like, the CPU is attempting to return to a non-existing address. This can be caused by insufficient stack space, or some error in the project. You can try to increase the stack space and see if it helps.

Thank you, SAMP.CY.

   

I created almost same project newly.

   

That was debugged completely, then I was convinced that ICE is not broken.

   

But I can't understand yet what the different is.
