I'm developing some USB code and everything seemed to work fine until I got to about 13.5k program size and now when I use some small functions to toggle I/O pins to control some signals like write enable, chip enable etc...code composer gives me this error.
It looks like there are some assembly instructions at 0x00000 but I don't know why. I haven't reached the 16k on my code limited license yet. This problem seems to be either intermitten or dependent on which pins I toggle first. I have no problem running any of the USB code, or any code for that matter, until I get to these simple void functions that toggle 3 or 4 pins that are set to digital I/O outputs. Has anyone else had this problem? Any advice on how to investigate this?
I'm using an MSP430F5637 with CCS version 5.4.
Thanks,
Rob
