STM32L476G-EVAL and ST-LINK/V2 Connection Problem
Hello,
For info, the default config for L476 Eval internal STLink is STLink V2-1, not Stlink V2.
For external STlink, it is STLink V2 (STLink V1 not supported by SW4STM32).
Also, you must not connect several Stlink to the PC.
It can be the case if the Eval board STLink usb connector is connected to the PC (for supply), In that case, you would have the internal STLink V2-1 of the eval board and the external STLink V2 connected to the PC.
It can be this issue when you get the libusb error access msg.
Regards,
Laurent
