FreeMASTER Plugin Config Failure

zuozuo · ‎01-09-2026

I was able to successfully conduct the CAN communication connection test in Figure 1, but after clicking OK, the fault as shown in Figure 2 occurred. How can I solve this problem?

In addition, I have used mbdt for freemaster development on S32K344, but I have not succeeded in polling mode CAN communication. Is it not supported? If it is supported, could you provide me with a sample, preferably for the S32K3 series

Hello,

we have identified the problem in FreeMASTER CAN plug-in and we are working on a fix. It appeared the plug-in has internally depended on Kvaser CAN driver and was not working correctly when Kvaser software was missing. It appears the Kvaser files are required even if using ZLG or any other CAN interface.

Before the fix is released in the upcoming FreeMASTER 3.2.7, a quick workaround is to install the latest Kvaser driver pack to your Windows system. You can download the Kvaser drivers here.

Thanks to all of you who had reported the issue and described the symptoms. Please reply to this message if installing the latest Kvaser drivers does not help to resolve the issue.

Thanks,
Michal

Hello zuozuo,
I am facing the same issue. can you please share any example model with me or just tell me how I can resolve the issue.
I also noticed one thing,
when there is only one CAN instance with single TX and Rx CAN object ID its working, but when we add more can instances each having tx CAN objectId and rx CAN objectId its not working, if you have solution please share with me.
Thanks.

I use the mbed toolchain to generate the underlying driver code for freemaster. Currently, both polling mode and interrupt mode can successfully connect with the host computer, and there are no issues with the slave computer. The only problem is that the freemaster host computer cannot save its own configuration options in the freemaster host computer project。
