CCS4: halt before or after power up

Hi

I read a file(FBPS.pdf) from TI which advices shut down powe before click halt.  I'm afraid I couldn't understand it quite much. I always click "halt" to stop the debug, then I shut down the power. Is that a dangerous action?

 

Thanks,

Violet

    Violet,

    I am not familiar with the document, but it depends on your system. If you are debugging a device attached to high-power MOSFETs, for example, you must shutdown all the high-voltage/high-current sections of your board before halting the device - otherwise the halt may cause damage to these sections and to whatever is attached to them (electric motors, actuators, etc).

    Keep in mind that removing power from the entire board (including the device connected to the emulator) will cause CCS to lose connection and throw an error message. Fortunately you usually need to simply reapply power to the device and restart the debug session to recover control.

    Rafael,

    Thanks for your reply. I'm always assuming "Halt" action will stop all outputs from DSC.  Am I correct? If I power down the board before "halt", will that cause any damage to the DSC? Do you mean that I can ignore the error messages from CCS--just  reapply power will be ok.   Yes, it would be a convenice and safe way to my POWER design system. (Yes, there are high-power MOSFETs on my boards). But I'd also like to make sure it wouldn't bring any side effects to DSC.

     

    Thanks again,

    Violet
