That seems likely, otherwise we'd noticed I'm sure ;)<br/>
But, given the example of the STM32F7 here, those class of devices has program cache because flash is rather slow, and if the thing runs one tight loop for a while, I guess the code would remain in the cache if not disturbed by jumps to other places, so the flash wouldn't be accessed during that time.<br/>
I don't think that that's what's saving the things from failure, though ;)</div>
