One Quick Observation , V2.23 takes so much time as compare to V2.22 ( windows 64 ) , for Reconnecting MCU & Throwing Error  after setting RDP2. approx 45 seconds by V2.23. while 5 seconds for V2.22 version.

Hello ​@bsuthar,

Could you specify the MCU you’re using? Or are you seing this across multiple devices?

      I tried with same MCU with 11 Different Custom boards.

      How “different”?  11 instances of the same design, or 11 different designs?

      What about ST boards ?

       

      Debugger : STLINK-V2 

      A genuine one ?

        ​@Andrew Neil 

        Debugger : STLINK-V2  , yes Genuine Only. has Back side series Number. Also, all other operation works fine with V2.23 itself.

        we tested on same design board of 11 pcs.

        Tried back with V2.22 , and ALL works fine, now.
