TMS320C6748: AER

Part Number: TMS320C6748
Other Parts Discussed in Thread: SYSBIOS

Hi,

After added code to call AER function aerGetSizes, I got the error message "unresolved symbol svdGetSizes, first referenced in C:/ti/aer_c64Px_obj_17_0_0_0/packages/ti/mas/aer/lib/aer_c.ae64P<aerinit.oe64P>" and "unresolved symbols remain"...

But call function areCreate is compiled no error. 

Can anyone help me to know where my problem is?

Thanks,

-Jay

    I am not the domain expert for this library but a quick look for that SVD symbols indicated that most of the svd functions are defined in the vpe module of that package. Have you tried including svd.h and linking the vpe library to your project.

    Rahul,

    SVD.h has been included, it is under ti/mas/vpe/svd.h

    But I can not find the vpe library, can you please direct me how to link vpe library?

    Thanks,

    -Jay
