i.MX RT - How To

[Leon_Li1]

Hi,

I have installed MBDT successfully, I can generated code use the default folder path.

But if I move the gpio_polling example to a new folder, I cant build it ok.

The message as below:

Build Summary

Hi @Leon_Li1 ,

We have a fix for the build error on 2021a. 

Please find the attached zip file - it contains a .tcl file. Unzip it and copy the file to: RTCESL_imxrt\bam\AMCLIB\bam_a32fltfltflt\ and overwrite the existing one: AMCLIB_PMSMBemfObsrvDQ_SF_A32fff.tlc.

Best regards,

Alexandra

It is ok, thanks for your help.

Hi @Leon_Li1 ,

Did you extended error look like below?

This is caused by the initial model being created with an older version of matlab, and some things changed in the data storage options.

To fix the issue click on a small icon in the left lower corner, to open the model perspectives:

Enter the Code perspective, and in Data storage type, fix the error for the 'A' storage variable:

Hope this helps,
