I can not compile a very simple PWM program on Keil The same program is compiled on Energia The message that I get is below: For your information main.c is in the source file and I use C not C++.

Suggests you're missing a bunch of source files, or a library, that you supplied with Energia.
The Linker will get closure when you supply all the pieces.
Energia is TI's Arduino-alike - isn't it?
So I guess - like Arduino - it hides a lot of necessary detail from you. Like providing necessary libraries.
Now you're moving to Keil, You're going to have to do all that yourself.
You should probably look to TI for support in taking an Energia project into a "conventional" development environment. Perhaps they have a tool in their Code Composer Studio ... ? (rather like Atmel do for importing Arduino stuff into Atmel Studio).
But you would have to ask TI about that.
I added all c files and now it builds correctly

But when I want to debug by step over I have :
*** error 65: access violation at 0x400FE608 : no 'write' permission *** error 65: access violation at 0x400FE640 : no 'write' permission *** error 65: access violation at 0x400FE060 : no 'read' permission *** error 65: access violation at 0x400FE060 : no 'write' permission *** error 65: access violation at 0x40025520 : no 'write' permission *** error 65: access violation at 0x40025524 : no 'read' permission *** error 65: access violation at 0x40025524 : no 'write' permission *** error 65: access violation at 0x400FE06C : no 'read' permission
do you have any idea
All the other "Error 65" posts are from people using the Simulator on parts Keil does not support simulation on. Use the debugger on real hardware.
