Which errors does EZ-BOARD LED5 indicate when running SigmaStudio?

I'm porting an existing algorithm to SigmaStudio for SHARC, and I'm trying to debug an occasional crash. There are two different flavors of crashes I'm experiencing in terms of the visual feedback I get from the test board (ADSP-214xx EZ-BOARD kits).


In the first case, when the program crashes, all LED's go dark. This is the most common case for me.

In the second case, when the program crashes, LED5 lights up. This is encouraging, since the SigmaStudio for SHARC Users Guide says that this is supposed to happen when an error occurs.


I suspect that I'm experiencing memory corruption somewhere, but I it would be helpful to know what can lead to LED5 (some specific subset of crashes detected by the board) lighting up as opposed to all LED's going blank (some serious crash which takes out the entire system).
