When you start Vybrid VF61x  /M4 core,  how does it get/set the SP from the firmware image, when

this is not debugging case where you can manipulate that directly?

 

In the Vybrid manual and the app note, it refers only to the "entry point of app"  which goes into SRC.GPR2, and some "argument"  (any param we want..?) into SRC.GPR3.   

And it says Boot ROM just checks if entry in SRC.GPR2 is valid address space, and jumps on it.  But no mentioning of setting the stack pointer. ...
