Real time kernel Error. S-function error.

Hello, i have a problem with the Real-Time features of MatLab.

I try to run some real time examples, but i always get an error message.

An error occurred while running the simulation and the simulation was terminated

Caused by:

• Error reported by S-function 'sldrtsync' in 'sldrtex_vdp/Real-Time Synchronization': Hardware timer cannot be allocated. Real-time kernel cannot run.

I searched on google but did not really found something.

I am running Matlab 2019b for academic use on a Windoes 10 System.

Thanks in advance!

Hi Christopher, I am facing same issue. Could you please post if you get any soluaiton for this issue.

I am also having this issue

Hi,

we solved the problem with de- and reinstalling the realtime kernel. Occurs after an Windows update...

hope that helps

greetings Sabine

I also faced this problem. I have tried uninstall and install back the realtime kernel but it seems not to work

• Error reported by S-function 'sldrtoo' in 'scope/ThingSpeak Output': Hardware timer cannot be allocated. Real-time kernel cannot run.

Possibly that message could also be generated if the design required more hardware timers than existed for the device. It has been years since I saw the messages posted for that context, so I do not recall at the moment whether that case would generate this message or would generate a different more-specific message.

Hello,

the inability to allocate hardware timer for the real-time kernel is most often caused by hardware or software incompatibility between the real-time kernel and the operating system or the computer mainboard.

First, please try to use the latest available release of MATLAB and Simulink Desktop Real-Time, because compatibility between the real-time kernel and latest updates of operating systems is being constantly improved from release to release.

If you are already using the latest version of Simulink Desktop Real-Time and think that the reason is hardware incompatibility, please go to Device Manager and search the System Devices section for High Precision Event Timer (HPET). If the HPET device is not present, it may be disabled in BIOS settings and needs to be enabled there.
