Dear all,

I developed a project for S3C2440 microcontroller on IAR Workbench v. 5.30,and I
am trying to debug code in external SDRAM.The program includes an array of size
of 153.6 thousand bytes.

When I download the code into SDRAM,the j-link shows this waring firstly:
"Write memory error @ address 0x30012664,word access:Core error.",
then a error message:
"Fatal error:WinRDI OpenAgent re-initialize failed.
[RDI Error: 242] Failed to initialize - configuration may cantain bad settings.
Session aborted!".

The address in the warning message is different each time.
However, I can see from the file suffixed with map, this address is always within
the framework of the array.

But when I kept trying,on occasion the program can be downloaded into SDRAM and
execute normally.And that if I canceled using the array,it is all ok.

My testing environment:
- J-Link ARM DLL V4.02a;
- J-Link hardware version 7;
- Hardware :My own S3C2440 with external 64MB SDRAM used;
- Software :IAR Workbench v. 5.30;

Have you got any idea about the cause of the problem?
Thanks in advance.
Best Regards.
