TMS320F28384S: The CM core booting

Part Number: TMS320F28384S

Hi champs,

In our example projects, we boot CM core before assigning the resources to CM, the GPIOs, USB, etc.

I am wondering is there any side effect if assign resources first before we boot CM core?

Regards,

    Hi Luke, 

    If CM code try to access before the assignment then it will be issue. If you have some kind of handshake between CPU1 and CM (e.g. using IPC msg) to make sure CM code does not access the resources then it should be fine.

    Hi Vivek,

    I understand that handshake between CPU1 and CM is a better method. The question is that if customer doesn't do handshake, is there any side effect if assign CM resources before he boots CM core?

    From my point, it should be okay, but I want to double check with team, please advise your comments, thanks.

    Regards,
