debugging error.

sriram k

Hi all
I have just started to use AT91sam9260 in keil 3.5v
When i write a simple prog... the compilations gives no errors. When I start debug it displays

"Error 65: access violation at 0xFFFFEE40: no 'write' permission"

I checked the previous posts and tried to change the memory address locations in Target options. Still it gives the same error. I am facing this problem only with ARM-9series. ARM-7 is working fine
plz help me to solve with this problem.

Thanks in advance
sriram

    When running on the hardware, it's the memory controller glue that may (or may not) generate exceptions.

    When running in a simulator, then it is obviously the Keil simulator (and the configuration to it) that decides if there will be a memory access violation or not.

    The question is still if there is expected to be any writeable memory at that specific memory address.
