*** error 65: access violation at 0x40025400 : no 'write' permission
Hi there! I´m really new to ARM / Keil enviroment so please be nice and bear with me. I´m trying to debug some code (examples) in Stellaris lM4f120 (launch pad) and I´m getting the error above. That happens whenever I try to access Periferal I/O registers or any other address above 0x4000.0000 in simulator mode, the only way out is to edit DEBUG->MEMORY MAP and add, for instance, the range 0x40000000, 0x400FFFFF. The problem is I lost this modification any time I recompile the code. My doubt is: Is there a better way to fix this? a file to edit, a option to check other than editing the Memory Map each time I need to debug the code?? (I guess I´m doing it totally wrong)
As it may be obvious English is not my mother tongue, so my excuses in advance.

You don't need to apologize; your post is a very good example for others to follow. You clearly stated your problem and what steps you had already tried. Your Summary described the problem. You used PRE tags appropriately. You even posted the solution that you found so that future readers of the thread could benefit.
I encourage you to come back anytime.
(Your English is quite good, too.)
I appreciate a lot your words Scott, as I´m new to ARM/KEIL, I´ll be around for quite a while.
