Hi all,
I'm working with a CC430F5137 and am finding a problem. While running a stability test (running several of our boards over the course of a few weeks and seeing if they remain up) I've found something interesting. In one or two instances a board will stop running as if it were stuck in a loop. This is strange for two reasons: I am utilizing the WDT, and when I connect through the debugger as outlined here: http://processors.wiki.ti.com/index.php/MSP430_-_Connecting_to_a_running_target and pause execution I get this error: "No Source available for "0x0"'. Why would the PC jump to nowhere, and why would the WDT not eventually restart the program?
My initial thought was that there was a memory read error while returning from a function so I put in a small ISR for VMAIFG that forced a reset. This appeared to fix the problem because we didn't see it again for a few weeks but now I've got yet another board going into the weeds, so that must not have been the error.
Thanks for any help you can offer,
Don
