  • Hi,

    > But is there any other way in keil

    The ULINK2 does various things trying to connect to the MCU. You can test the Connect Settings for the ULINK driver, play with
    Connect: Normal / under Reset / pre Reset
    Reset: Autodetect, HW, SYS and VECT

    The ULINK also tries internally to connect, but if the device decides to be locked our debugger has no chance.

    The LMI Flash Tool does some "crazy pin-toggling" sequences with the FTDI-JTAG to bring the MCU back to live. When I was working with the first unlock tools, there were several possibilities to go through - I think now they packed them all together and try them through...

    .
    Please try this tool if it solves your problem. And please write a note here even if you succeed.
