Problem booting xpc target over network

Hello, When trying to boot from a network the xpc target computer does not start. On the target computer I receive the following error: "RTTarget-32 CPU Exception 000E". This xpc target computer has been operational in the past, using Network booting with the same configuration and was not used for some weeks. Windows host computer with Matlab 2013a. Host and target connected with crossover cable.

For the network boot the following steps were followed:

1. Create network boot server (xpcnetboot.bat - using xpcexplr->Boot configuration-> boot mode: Network -> Create boot disk)

2. run xpcnetboot.bat

3. turn on target computer. In host I can see "Received request from 10.0.0.4" (and MAC address appears above bootserver icon which is the same as in xpcexplr) - so network connection seems ok (host ip: 10.0.0.1)

4. Then, in host command window we get the following: "Error: wrong Opcode 5 ... TFTP aborted" (attached)

5. In target computer we get "CPU Exception" (also attached)

If I then try testing, even ping fails (both from command window and using xpctest). I also tried to connect directly from xpcexplr and directly using tg = xpctarget.xpc('xCoreTarget') but does not connect. I also created a CD and tried to boot with it, but same error/screen appears in target pc. However it does not seem to be a hardware problem because I could boot with Ubuntu from a USB.

Am I doing something wrong? any ideas?

Thank you!

I have exactly the same problem, though I am using 2014a. It was working last year, but when I tried to run it last week, it generated the same error (CPU Exception 000E error code 0004). Any suggestion would be helpful.

I could solve the problem by disabling USB ports in BIOS in the target PC.

Thanks!

I couldn't disable the USB ports from the BIOS in the target PC, but found a similar solution. Using xpcexplr I unchecked "USB support" in Target Settings and then created a new boot disk. It now works! :)
