Upon upgrading to the latest release 2017a my Simulink real-time setup which has worked for many previous versions of Matlab has ceased working. When running slrttest it completes the first few tests succesfully and then fails during Test 4 giving the error message:
LoadDLM: WriteFile Error
I have been through all of the troubleshooting steps suggested for Simulink Real-Time in the documentation and seeing as I was running this setup perfectly with 2016b with no changes to the target PC or anything else it did not help correct any issues. I have tried using different compilers but to no avail.
I am using a Quanser Q8 PCI board in my target pc.
Edit: I did create a new boot disk for the target PC in Matlab R2017a.

Hi Louis,
I understand that you recently updated Simulink Real-Time from R2016b to R2017a, and now with the same target PC, 'slrttest' fails at Test 4: Build and Download slrttestmdl. I also assume you have performed all the steps listed in the documentation below:
Because you said that you have made no changes to the target PC, my guess is the target kernel version does not match with current MATLAB version. In your case, the target kernel may still be in R2016b while the MATLAB is in R2017a. In other words, the Simulink Real-Time version, which you can find by typing ">> ver('slrt')" in MATLAB Command Window, should match with the target kernel version seen on the target machine screen.
Therefore, please make sure to re-create a boot disk for the target PC in R2017a before running 'slrttest'. For instructions on how to create boot disk, please refer to the following doc page:

I have confirmed that the development computer can ping the target computer, and when running slrttest it completes the first three tests succesfully. And I also have performed all the steps listed in the documentation below:
However, it fails during Test 4 or building simulink model manually giving the error message:
The call to slrt_make_rtw_hook, during the exit hook generated the following error:
TargetPC1: LoadDLM: WriteFile Error
The build process will terminate as a result.
Caused by:
TargetPC1: LoadDLM: WriteFile Error
So how to solve this problem? Thank you very much!

Hello, I have exactly the same problem.

Mohamed, Louis, I'm not sure how many people reading Answers will have access to that specific hardware configuration to be able to help you diagnose the problem. I recommend you contact Technical Support using the Contact Us link in the upper-right corner of this page and work directly with the Support staff to determine the cause of this problem.
