Is it mandatory to cut off the Nucleo board in order to use PA13 and PA14 to program with ST-Link/v2?

Hi everyone,

I play with a Nucleo-F767ZI, using the ST-Link part provided on the PCB.

I would like to use a ST-Link/v2 to program my MCU.

I was wondering, whether it is possible to power my MCU (without USB PWR) and use the ST-Link/v2 (using PA13 and PA14), without cutting the ST-Link part of the Nucleo or removing other components off the board.

UM1974, on page 71, says:

and:

My guess would be, I can't, but I don't understand why? 

Do you have an explanation?

Cheers,

Ced.

There is a schematic if you are interested in the electrical connectivity on the board.

You can remove the CN4 jumpers to disconnect the ST-LINK from the onboard target (F767)

Yes, you can connect directly to Nucleo board without cutting or removing any parts.

There are two processor on that board, one for programming and a target.

To disconnect the on board target, remove jumpers CN4 as described by St. Clive.

also described in the Nucleo-144 document.

then you can connect your new target board through the 5/6pin connector provided.
