System Workbench for STM32

Hi,

I don't know, maybe use the internal STlink v2-1 for this.
Also, can you try to change the switch of Boot0 pin to 1 and reset.

Another idea, maybe the PCrop R/W protection is set too ?

Check that you have the "connect under reset" and "debug in low power modes" options activated.
Reset mode should be "Hardware Reset".
And i have SWD at 1.8MHz.

Can you upgrade the STLink firmware ?
