Embedded ST-Link in NUCLEO Board

[Chaim]

Hello,

I have NUCLEO-H755ZI-Q ST Board. To initialize the board, I used the STM32CubeMX initialization code generator ("Start My project from ST Board").

The Debug in this initialization is set to "Disable" (i.e., no Serial Wire or JTAG is active).

How the onboard embedded ST-Link operates with debug disabled setup?

BR, Chaim

Hi,

the st-link is connected to swd/swc ; at/after reset the chip has this working at this pins always, so it can work.

But if you set/use this pins for any other function, you loose connection.

You just can connect then "under reset", to flash the chip or set pins swd/swc for debug again, then you can debug the program you flashed "normal" again.

read in rm , debug...
