Another debug launch and target program/erase failure......
Hello,
Did you update the software: menu Help => Check for update
The nucleo F401re has a Stlink V2-1, not V2.
So, use the default script that is inside the software (nucleo_f401re.cfg).
The error you get is “open failed” at the begining so i suspect a libusb issue.
Either you have another session not terminated, either the driver is not installed correctly ? admin rights ?
Or you didn’t close the STlink connection on another software ?
Rgds,
Laurent
