Model-Based Design Toolbox (MBDT)中的主题 Undefined reference error using GDFLIB

Undefined reference error using GDFLIB

rafael_barbosa — Fri, 19 Jun 2020 11:19:49 GMT

Hello,

I am using the MBD toolbox 3.0.0 and the target micro-controller is MPC5744P.

I can generate code using GDFLIB blocks (thanks Reference to non-existent field 'info' using GFLIB block ), however I can't debug it (neither flash it in the micro) using S32 Design Studio.

I am using the block GDFLIB_FilterMA_FLT in Simulink.

After code generation and importing the project in S32 Design Studio, I am getting the following error when building project:

Can you support me with this problem?

Please see the example model attached.

Hello rafael.barbosa@chassisbrakes.com ,

This issue is due to missing library from linker arguments. It is an older issue that was fixed in the more recent releases, but the workaround is simply: you right click on the project that you have imported into S32 Design Studio, go to C/C++ Build -> Settings -> Standard S32DS C Linker -> Libraries, and add the following (from the green + signs), as in the picture below:

":MPC574xP_AMMCLIB.a" -- add this to Libraries
"{TOOLBOX_DIR}\mbdtbx_mpc574x\AMMCLIB_MPC574xP\lib\s32ds_ppc" -- add this to Library search path

This should do the trick - let me know if you have further issues with it.

Kind regards,

Razvan.
