Simulink Real-Time CPU overload in standalone mode

Hi,

Using 2017B and a Speedgoat Mobile Real Time Target machine we are seeing CPU overload errors when built and run in standlone mode, but exactly the same model built and run in normal (DOS loader) mode runs fine with no overloads. The model is an automotive controller using CAN and UDP connectivity (no phyiscial I/O).

Anyone got any ideas where to investigate more to understand this problem?

Thanks.

We are having exactly the same issue.

I have encouter the same issue. Got any solution already?

Sorry no - recently tried same experiment on R2020a version and same result.

I've basically given up on the standalone mode - I just think that not many people use it, and consequently they don't really maintain or develop it as well as they could.

I had the same issue. For me disabling "USB Support" in the target settings solved it.

Also the disable SMI block from https://de.mathworks.com/matlabcentral/fileexchange/18832-disabling-smis-on-intel-r-ich5-chipsets works well if you have a supported chipset.

Thanks for the ideas - I'll give them a go and let you know if it works
