Getting ST-LINK-V3 MODS to run after previous used of nucleoboards.

Hi,

i was hoping, that the Link-V3 would just work, after i used nucleo boards already. But i was dissapointed. I use the GDB server, and it says:

ST-Link enumeration failed

Error in initializing ST-LINK device.
Reason: ST-LINK DLL error.

I just checked a Nucleo board, and there is no problem.

The installation of the driver worked without errors.

IT WORKS!

While trying many things, i disconnectes NRST. But i still can program the target.

I had to enter the frequency in the gdb server comman line!

Can you connect with STM32CubeProgrammer? If not, at which stage does it fail? Does the ST-link show its serial number? Does the target voltage show up and is it valid?

Since this is custom hardware, was it ever working correctly or is this a first try? Does it have power, are pins connected correctly, is VCAP correct, etc?

    It now works. I think i may have to turn / plugin the cables in a certain order.

    But i now have this Error:

    Error message from debugger back end:
    Error finishing flash operation

      I have now made more measurements:

      The signal have the right levels without a T_VCC connection.

      This is how i start the GDB server:

      ST-LINK_gdbserver.exe -p 6100 -l 0 -d -s -cp D:\...\tools\bin -m 0 -g
      start "" STM32_Programmer_CLI.exe -c port=SWD mode=NORMAL reset=HWrst

      See the settings for eclipse attached.

      I now managed to get some connection to my board. I used the Cubeprogrammer GUI, and have to set 1000kHz or lower. But still it does not work with the CLI, allthough it there set 1000kHz too.
