(my original post had this all int he title line, reposting)
This may span into KDS and the Kinetis SDK. But I am bringing up a K22FRDM board with a Segger Jlink base debugger, and the KDS environment. I am using the SDK startup code, and and properly disabling the watchdog on powerup. But I am still getting an interrupt (which leads to the default unhandled interrupt loop). This happens if I just do a main() while(1) loop and happens a few seconds after startup. How do I determine the source of an interrupt? I have referenced ARM documentation TRM for arm_cortexm4 and looking at the NVIC entry, but there isn't much listed there. What registers would I look for in the debugger to see what the ISR source is? And what is the method in KDS to open a memory dump/display window?
