Does anyone have any bright ideas on how to figure out what piece of code is running from flash? Here's the problem -- I boot from flash and copy all of .text and .vectors to RAM. The C init code initializes the variables from flash, end them I'm supposedly running 100% from RAM. Except that I'm seeing a regular, short flash access. Its so quick that I can't even tell how often it is (the 468 scope doesn't have enough persistence for me to see both triggers when I expand the timescale). So, I've got a rogue piece of code doing a little flash access (2 strobes on A0), but not much. I've already stared at my memory map (output by the linker) and the only possibilty I can see is the .cinit section, but it only gets copied at bootup, right?
