Check in Mixed mode after Download first if your memory content is ok.

The root cause of this problem is in some sensitive registers corrupted during initial device initialization before entering this __start subroutine.

Hi phaneesh,

we are also facing the same issue software emulation exception can you suggest how to solve the issue and the configuration file looks same as you were used with 66Mhz.
