Access violation at 0xFFFFFFF4

Dear Martinmohsen Gholami

Hi,
I am new in ARM programming using keil.I tried to debug a sample code in the keil compiler but I have this error when i pressed f7:
Error 65: access violation at 0xFFFFFFF4.I saw the thread to solve this issue. some body said I should add following line to my ini file:
MAP 0x40000000, 0x40001FFF Read Write

I have done it but the Error 65: access violation at 0xFFFFFFF4 is appeared again.
which place i should be add above code to my ini file ?
my ini code is like this:
BREAKPOINTS]
ShowInfoWin = 1
EnableFlashBP = 2
BPDuringExecution = 0
[CFI]
CFISize = 0x00
CFIAddr = 0x00
[CPU]
OverrideMemMap = 0
AllowSimulation = 1
ScriptFile=""
MAP 0x40000000, 0x40001FFF Read Write
[FLASH]
MinNumBytesFlashDL = 0
SkipProgOnCRCMatch = 1
VerifyDownload = 1
AllowCaching = 1
EnableFlashDL = 2
Override = 0
Device="AD7160"
[GENERAL]
WorkRAMSize = 0x00
WorkRAMAddr = 0x00
[SWO]
SWOLogFile=""
[MEM]
MAP 0x40000000, 0x40001FFF Read Write EXEC
RdOverrideOrMask = 0x00
RdOverrideAndMask = 0xFFFFFFFF
RdOverrideAddr = 0xFFFFFFFF
WrOverrideOrMask = 0x00
WrOverrideAndMask = 0xFFFFFFFF
WrOverrideAddr = 0xFFFFFFFF

What should i do to solve this problem .I would like to debug lines of my code step by step.

I would be grateful if you can answer this question

thanks
Mohsen

    I use lpc1768 from NXP product and in simulator mode ,I did what you offered that means I wrote -REMAP in cpu DLL Parameter text box and I added following line in the first line of ini file :

    MAP 0x40000000,0x40001FFF Read Write


    But in addition to prior error a new error occurred which name is error 10:syntax error as below:


    Load "D:\\M.gholami\\ARM Projects\\Philips\\Keil\\Osciloscope(Programming whit USB bootloader)\\osciloscope.AXF"
    Include "D:\\M.gholami\\ARM Projects\\Philips\\Keil\\Osciloscope(Programming whit USB bootloader)\\JLinkSettings.ini"
    MAP 0x40000000, 0x40001FFF Read Write
    [BREAKPOINTS]
    ^ *** error 10: Syntax error
    *** error 65: access violation at 0xFFFFFFF4 : no 'write' permission
     my ini file is:

    MAP 0x40000000, 0x40001FFF Read Write
[BREAKPOINTS]
ShowInfoWin = 1

RdOverrideAddr = 0xFFFFFFFF
WrOverrideOrMask = 0x00

    I can debug my codes simply with jlink but in simulator mode i have errors which i talked about.Please help me more.
