FreeMASTER Plugin Config Failure

[zuozuo]

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

I use kvaser for CAN connection and testing, and everything works successfully; however, when I use the zlg driver, the aforementioned issues occur.

I am using PEAK CAN and still face this issue.
Can you share simulink model. My S32DS studio example is working in Design Studio.

Hello,

we are trying to analyze and resolve the issue, but unfortunately we were not able to replicate it on any of our test platforms. Please use the manually-edited connect string until this is fixed.

One question: when ZLG/ZCAN driver is selected, does the error appear when you press  the CANCEL button in the plug-in dialog?

Thanks,
Michal

I am using the PEAK CAN

[zuozuo]

I used the version FreeMASTER 3.2, but following your method, it didn't work on either of the two computers I tried.

[gzleng]

quickly ran from another computer with an earlier version of the pc side software and it worked fine. so i manually copied the connection string to the Option field and it worked. so the issue is either on the 1.16.0 or the PC admin previlage..

Hello,

one thing to try is to re-register the CAN communication plug-in in your system. Please close the FreeMASTER, and navigate to installation location. Then run the register.bat "As administrator". See more details in one of the earlier posts in this forum.

Hello, according to the method shown in your picture, I am using the freemaster3.2 version of the host computer. I have tried on both a Windows 11 and a Windows 10 computer, but neither worked,

Hi, Michal,

thanks for the hint but it does not seem to work. by pasting a plain text string i could open the port. the computer that i had an older version of Freemaster 3.2 no longer works after i upgraded it to the latest version. i ran the register.bat as admin but the same error message appears. now two computers give me the same error.

The same problem has also occurred here. I suspect that the CAN Pluging in version 1.16.0 added the FD function, which caused an error in string generation and parsing.

[MichalH]

Hello the CAN plugin version 1.16.0 (in FreeMASTER 3.2.6.3) indeed adds the CAN-FD support for ZLG and some other vendors. It also adds support for the new ZLG ZCAN library. After  the registrer.bat has been run, we can be sure the plug-in is correctly registered in the system.  

I cannot replicate the issues you are facing. The connection string for the ZCAN devices appears normally in my  case:  drv=ZCAN;port=1;bitrate=500000;cmdid=0x7aa;rspid=0x7aa;tmo=500

Please try the following:

1. Paste the ZCAN string to the Options dialog manually and then open the plug-in configuration. Then close it without making any changes. Will it still show the error?
2. Just as an experiment, try to enable the CAN-FD mode for the USBCANFD_200U device and press OK.
3. Try to select another CAN driver, for example IXXAT, even if you do not have any physical device, then press OK.

Please let me know if it shows the error in all 3 cases.

Thanks,
Michal

Hello！ 1. I manually added the information you provided to the command bar, then clicked "configure", and after entering, I clicked "ok", everything was normal. 2. Since I manually added the command information you provided correctly, everything has been normal. Whether I check or uncheck "canfd" is normal, even if I clear the command line, reconfigure it, and then click "ok", everything is still normal. 3. I use Kvaser, and everything is normal

[baiRB]

Thank you for your reply. I tested the above three steps, and each of them would report the error: "The plugin configuration dialog failed. Try to specify the connectstring manually". Additionally, I have run register.bat in administrator mode.

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

[KaleRushikesh]

Even for PEAK-CAN we need to do this?

[MichalH]

Hello,

theoretically yes, you may need to install Kvaser drivers even in case you use a PEAK device. The dependency on some Kvaser files causes the Plug-in configuration dialog to fail when creating a connection string regardless of the device selected.

It may happen by some lucky coincidence that the issue will not appear with PEAK or other devices, but if it does, installing the Kvaser driver shall always help.

This issue will be fixed in future FreeMASTER version.

Michal

Yes,It's useful.

Now I have also implemented the polling mode and tested the connection of the can based freemaster. The effect is the same as the above picture. I will continue to seek help

Hi @zuozuo,

Are you using the MATLAB or S32 Design Studio as your primary development environment ?

In the later case - did you try the example applications that come with FreeMASTER Driver Update site ?

In case you are using MATLAB, a dedicated team is handling the MatLAB Toolbox and I will move your query to MBDT community space.

[zuozuo]

I use the matlab 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.
