[STLink-V3PWR] in procedure 'program' ** OpenOCD init failed **

[FroggyCorp]

Hi,

I'm using last version on W10 with vscode with a STM32L0 serie and STLink-V3PWR :

pio upgrade
You're up-to-date!
PlatformIO 6.1.18 is currently the newest version available.

On upload, i get :

Configuring upload protocol...

The openocd version with PIO 6.1.18 is 0.12.0 -01004:

It should get a newer version. :

For faster change, the stlink.cfg need to get the new one :

Thanks in adavance,

In fact, changing the .cfg or copying the newer openocd inside still make an error. I suppose there is a script somewhere ?
