Random occurences of timeouts while reading variables

fbw — Thu, 23 Jul 2026 15:39:38 GMT

Hello, I have been working on a battery test rig set up by my predecessors on the project.
The test rig uses an nxp S32K144EVB board connected via usb to a computer.

The code is built from a simulink file and monitoring of the test is made via FreeMASTER 3.2.

The project has been working on a laptop for a few months and it has been necessary to configure a new laptop as a replacement. However, even while installing the same FreeMASTER version, the same drivers and using the same project files, all variable reads as "?" due to timeout errors after a seemingly random duration.

Any help would be greatly appreciated.

Logged errors after 12 minutes of runtime with no issues :
