We are using MATLAB2023a scripts to generate code after compiling Simulink models, then call eclipsec.exe to perform headless background compilation. Once the build is completed, a hyperlink is created in the Simulink Diagnostic Viewer to directly open the workspace corresponding to the compiled project. This workflow worked perfectly with S32DS 3.4. However, after upgrading to S32DS 3.5.8, two issues have occurred: Issue 1: Clicking the hyperlink that's created by Simulink will launch the background process s32ds.exe, which then pops up and exits immediately. We have tried several solutions like adding the parameter "-vm \bin\javaw.exe" to s32ds.ini (this has no effect on s32ds.exe), and prioritizing the JDK 11 path in system environment variables. None of these attempts resolved the problem. Issue 2: As previous described, calling eclipsec.exe via MATLAB scripts triggers the error shown in the screenshot: Java was started but returned exit code=1. We set "\bin\javaw.exe" and JDK 11 path at the top of system environment variables. The Command Prompt correctly displays Java 11 (64-bit), yet Simulink compilation still attempts to load jvm.dll. After deleting "client\jvm.dll" or "server\jvm.dll", the program will locate java.exe instead, but still reports an error with exit code=4. In addition, manual compilation remains successful in all cases. All the related files and settings will be uploaded for your reference. Please help give your advice to fix this. Thank you.</P> Fri, 12 Jun 2026 08:31:47 GMT Zack_Fang 2026-06-12T08:31:47Z https://community.nxp.com/t5/Model-Based-Design-Toolbox-MBDT/Matlab2023a-Envokes-S32DS3-5-Encountered-Error/m-p/2380654#M10773 <P>Dear MBDT Team.

Then you have set up a workflow to compile the code using eclipsec. The main problem I see is that MATLAB do not currently use the correct Java version. Have you tried to contact them about this problem?<BR /><BR />Moreover, I suspect that you don't use Model Based Design Toolboxes developed by NXP (e.g. S32K3, S32K1 etc). Let me know if I am wrong.<BR /><BR />Best regards,<BR />Sorin Bancila<BR /><BR /><BR /></P> Wed, 12 Aug 2026 12:18:26 GMT https://community.nxp.com/t5/Model-Based-Design-Toolbox-MBDT/Matlab2023a-Envokes-S32DS3-5-Encountered-Error/m-p/2404230#M10790 SorinIBancila 2026-08-12T12:18:26Z
