    Hello,

    Yes, you could use these points for an external probe.

    Should work without specific embedded ST-Link disable (obviously, to avoid conflicts, you must not start any debugging session on ST-Link), and you could still use UART4 VCP thru ST-Link USB.

    Please ensure you have the latest ST-Link FW.

    Anyway, In case of trouble, you could totally disable ST-Link (debug and VCP) using SB18, or just disconnect ST-Link SWD wires using SB17, SB19 and SB20.
