Disable SWD pins

Hello

Can we disable the SWD pins (After Boot) ?

If so, will it be a problem connecting again with the debugger ?

The goal is to minimize current consumption....

Thanks

Edi

Hi Edi,

yes, it will be a problem to connect with the debugger after you have disabled the pins.

What I do is this: I wait some time after boot (say 2-5 seconds) until I disable the SWD pins. This gives me time after reset to connect to the board with the debugger.

I hope this helps,

Erich
