I am using Atmel's AT91SAM9RL-EK evaluation kit which came with a SAM-ICE device for connecting to the dev board. After connecting the SAM-ICE to the USB port the LED goes solid. J-LINK seems to be able to communicate with it. I am using IAR for compiling and debugging. When I try to start the debugger I get the following error in a message box:
"SAM-ICE can only be used with ATMEL devices"
The debugging session fails. I have also tried using SAM-BA, but get the same error.

Here is the debug log for IAR:

Here is the information I get when I start J-LINK:

My coworker has the same kit so we have tried exchanging hardware, but he gets no error and I always get the same error. Anybody have any ideas what might be causing this error?

Solved the issue. I uninstalled J-LINK and IAR, then installed IAR first, and J-LINK second (I did it the opposite way the first time). Now debugging works.
