How Can I use RTOS in MBD toolbox for spc5744?

[剑明肖]

Hello,

I want use some RTOS in my program, such as ucos, FREE rtos. But I don't know how to add it with MBD Toolbox. Is it possible to do this and how ? Any suggestions will be greate helpful for me. Thanks.

您好，我想在我的程序中使用实时操作系统，比如ucos/free rtos， 现在我不知道怎么在MBD toolbox模块组成的程序中添加，结合SPC5744的MBD toolbox，是否可以添加实时操作系统？如果可以，该怎么添加？感谢提供的任何建议。

Hello,

You are not the first to ask this - and most likely not the last one!

To be honest with you - i've not tried this so far, but it seems to be an interesting topic. If you are willing to invest your time into this, then we will be more than happy to support&learn with you.

At this point, i'm not fully aware of what does it takes to make it run - but i know we might be able to support such mechanism via:

- NXP Toolbox;

- Simulink Coder;

STAGE 1 (easy): copy all RTOS required files (sources + headers + libraries) into the Simulink Code Generation Folder. This can be done via mbd_pnt_user_copy_required_files.m what is automatically invoked during code generation. Check this for how to: https://community.nxp.com/thread/449904#comment-900775 

STAGE 2 (tricky): invoke RTOS into the Simulink Model. For this you will have to use 2 basic approaches for custom/legacy code generation.

• Custom S-functions (https://community.nxp.com/thread/449904#comment-901737)
• Simulink Coder Custom Code insertion block in various parts of the generated code & Simulink functions.

Anyhow, at this point i do not know how you could integrate Simulink models with RTOS without building re-writing the TLC behind some of the NXP's toolbox function blocks.

Hope this helps!
