Real Time Windows Target (RTWT) in Windows 8

Hi!

I'm running a Windows 8 64 bits laptop, with Matlab R2013b, and I have been having issues with RTWT. I installed the real time kernel without any problem and when I tried to run any of the demo models (rtvdp or rtstreamio) in both normal or external mode (after compiling) the computer hangs and time stays at 0.00 seconds. I then have to force Matlab shutdown. This issue also occurs on a Desktop running Matlab R2013a and Windows 8.1 64 bits. Sometimes I get a Blue Screen Of Death with the message CRITICAL_STRUCTURE_CORRUPTION, which according to Microsoft is "indicates that the kernel has detected critical kernel code or data corruption." On the other hand I have another laptop with Windows 8 x64 and Matlab R2013a that runs RTWT flawlessly. Is this hardware dependent and not OS dependent?

I appreciate any help.

Thank you, Paulo Melo

I'm running into this same error. I I am running windows 8.1 64 bit on a Lenovo Y580 laptop. Running

rtwintgt - install

Didn't do anything for me.

From what you describe, it appears that the base hardware clock that drives the real-time kernel does not get initialized properly. This really looks like a hardware-specific issue, perhaps in combination with Windows 8. We have never had such a report for Windows 7 which is the most commonly used platform and I'm sure we'd have heard about it if it was happening.

I don't have any real solution, other than contacting technical support with details of the machine having the problem. You can also try to set the "useplatformclock" OS option to "on", as described here , but I don't know whether it will help or change anything.

I cannot comment on Windows 8.1 at all because it is not yet released and the product has not been quailified on it yet.

I'm having the same problem with a computer running Windows 7 64-bit. I didn't happen to catch the error message cited on the blue screen, but it's definitely caused by the Real-time Sync block. How can I get help on this?

[Mr T]

Figured it out. I needed to update my real-time Windows kernel by running:

rtwintgt -install

I was getting blue screens and needed to restart on windows 8.1 64 bit, when i ran a script. On the other, exact same machine and same Matlab 2013 b version, no problem at all. rtwintgt -install worked for me as well
