The model design based on kV Series MCU encountered errors when compiling and downloading

nxp model-based design toolbox for kinetis V31——example projects

An error was encountered in the process of compiling and downloading. The error message is as shown in the attachment. Could you please tell me how to solve this problem?

Hello,

Please see this post: https://community.nxp.com/t5/NXP-Model-Based-Design-Tools/Cannot-run-i-MXRT1060-examples-from-the-NX.... It should fix the issue.

Best regards,

According to your prompts, I modified the preferences of Matlab, as shown in the figure below.But the same problems still arise.

A restart of the matlab did not work? If you see the same error that mentions 'zh_CN' then it might not applied the changes done in preferences. Also delete the generated <model_name>_ert_rtw folder, and any cached data of the model. Also, after changing the locale data time format in preferences, run again the mbd_kvx_path.m script.

After careful study, I found that the time and area format Settings in Matlab should be consistent with the system Settings.Change the time format Settings in the operating system

I run the MBD_KVX_PATH. M script and the output was successful

Then, I recompile and download the model,

The error is as follows:

According to the link you just provided

I imported "sdk_2.8.0_frdm-kv31f_configtools_data.zip" into the ConfigTool.When I'm done and open the Configure button again, a window like the one below pops up

However, the same problems still occur when compiling and downloading.

Also, I would like to ask, where should frdmkv31f_gpio_pollingconfig.mex appear?Why didn't I see it?

nxa11767 · ‎01-12-2021

The frdmkv31f_gpio_pollingconfig.mex should be next to your model. Like in below screenshot:

Browse to the example folder and you should see it there. On a clean installation the .mex is not there, but will be copied when the .mdl is opened. Some examples will have a .mex associated because those example have particular settings exactly for that example.

After build, you'll see two folders being created: frdmkv31f_gpio_polling_ert_rtw and frdmkv31f_gpio_pollingConfig. Delete these folders and try again. From your screenshot I can see that the processor data was loaded correctly in the Configuration Tool and I don't see any errors when the model mex was opened.

: frdmkv31f_gpio_polling_ert_rtw and frdmkv31f_gpio_pollingConfig

After deleting these two folders, I recompiled and downloaded, and successfully solved the problem.

As for the problem that the time format cannot be recognized, I would like to share my experience. If it is a Chinese operating system, then the system Settings and MATLAB Settings should be shown in the following figure.
