Starting with the "hello world" app I wrote very simple code to generate an interrupt when PIT0 is reset.
When I use the RAM compilation target, the interrupt handler fires as expected (periodically blinking an LED on the demo board). However, when using the CONSOLE_RAM target, my application throws a bus error when the interrupt fires.
But here is the odd bit:
To link in my interrupt handler I pointed vector119 in mcf5xxx_vectors.s to my handler. When I use the CONSOLE_RAM target, it seems that this vector table is not even being linked into my application: I can enter a function that does not exist for vector119 and no linker error is signaled. Using the RAM compilation target, I get a linker error as expected if a vector refers to a function that does not exist. And furthermore, as I said, my handler is in fact the one that fires when PIT0 expires, when I use the RAM option.
My question is: Is there something obvious I am missing about the CONSOLE_RAM compilation target, where it grabs the vector table from somewhere other than mcf5xxx_vectors.s? If so, where is it getting vectors from? If not, is this a bug?
