MATLAB: Am I unable to ping the xPC Target system using MATLAB 7.4 (R2007a) boot disk but I am able to ping it with an older version of xPC Target

Simulink Real-Time

I have the host and target system connected via a TCP/IP connection. I have both MATLAB 7.4 (R2007a) and MATLAB 7.0.1 (R14SP1) in the host machine. I am creating the boot disk for the xPC target using both the versions of MATLAB. I boot the target system using the boot disk from MATLAB 7.0.1 and when I ping the target the ping is successful. However when I reboot the target system using the boot disk from MATLAB 7.4 I am not able to ping the target. The operation times out. Why is this happening?

Best Answer

One possible reason for this behavior is that R2007a supports more Ethernet chips and the motherboard for this target machine has a built-in Ethernet port that is currently supported.
If there is a built-in port, try plugging the Ethernet cable in there and see if you can ping it now. If that works, you can remove the extra Ethernet board and you've gained an extra slot for an IO board.
