Part Number: TMS320F28P650DK
Other Parts Discussed in Thread: C2000WARE

Tool/software:

I have not used the dual-core lock step function before, and now the servo side uses TMS320F28P650DK9.

I would like to ask a few questions:

1. The dual-core lock step is CPU1 and CPU2, right?

2. Does the code in both cores have to be the same?

3, About the dual core lock step (Lockstep Compare Model) is there no Demo?

Hi User,

No lockstep is between CPU2 and its shadow CPU2, please refer to device datasheet and manual LCM chapter

Since CPU1 is independent core and CPU2 is in lockstep they can be having independent code and tasks

C2000Ware has driverlib functions and software diagnostic library should provide you examples

SDL path : {C2000WARE dirc root}\libraries\diagnostic\f28p65x\source

Thanks
