unable to stop at break point

I've used the EKS-LM4F232 board with CCS 5.5 and have not encountered this type of error nor have I heard other reports of it. Are you using the ICDI on-board emulator?

Does it happen every time the code halts at a breakpoint?
Does it happen with the Stellarisware example programs? If so, please let us know a specific example with which you see the error and exactly what steps allow you to reproduce it, so we can see if it is reproducable at our end by following the same steps.

I am using vmware running a Guest Windows XP.

Basically, I try on "hello" and "blinking" example and even my own created example. One thing I must mentioned is I am using the latest compiler version instead the old (preset in all example). These are the only thing I have modified so far.

I have also done the re-install but the problem seems not resolving.

PS: I am able to flash my board but just couldn't stop at specific break point! 

I assume you are using the onboard ICDI emulation. I suspect the problem could be due to vmware. That is the only thing I see different than other typical users. I myself use this board quite frequently and have not experienced any issues with breakpoints or stepping through code.

As a test, can you install CCS on a native Windows machine and check if the behavior persists?

I did not use vmware for a while now, but I remember that there is a setting for USB port handling.

I would check that first before reinstalling the CCS app.

May I know what are the settings? It will be great if you can share it over here. Thank you!

Unfortunatelly I am not around a vmWare installation.

The setting is part of the virtual OS configuration where you configure the way IO ports are used by the virtual machine.
