Using ST-LINK V2

Hi

  I have been using a Nucleo board (STM32L0 and STM32L4) and now want to design my own boards. I have been looking through the web and found information on pins to use. I want to make sure I use the correct ones before I design my board. I want to debug the code too.

 

I was thinking of connecting the ST-LINK V2 as follows:

 

STM32L4    ST-LINK V2

SWCLK   -----> PA14

SWDIO   ------>PA13

0V --------------->0v

3.3v-------------->3.3v

NRST ----------->RST     (some have this, but others say not needed)

 

Would this be all that is needed to program and debug a chip? 

 

Also, I assume by doing the above, PA14 and PA15 cant be used for anything else?

 

Many Thanks

Scott
