Can't load drivers - 'The driver could not be installed. No mbed Microcontrollers were found'.

Loading drivers for Nucleo-F401RE - I get the 'The driver could not be installed. No mbed Microcontrollers were found' message. When I connect the USB to the PC it opens explorer and sees the board as an external drive.

I could not find allot of information on this board - Is there a user manual? What are the jumper links for?

Nucleo ones use their own code seperate from the code that is used for Freescale and NXP devices. Following this list should fix it for you: http://mbed.org/teams/ST/wiki/Nucleo-Firmware

Regarding user manual: IIRC my F401 had a page with it with the different jumper settings. Anyway here is a complete document: http://www.st.com/st-web-ui/static/active/en/resource/technical/document/user_manual/DM00105823.pdf. I useful if you got problems to check it, since on my board they kinda forgot to put the main power jumper in place (luckily they do have two spare jumpers).

I'm having this same problem with my NUCLEO-L152RE board. I've successfully performed the firmware upgrade following the steps listed in the link, but I still get the 'The driver could not be installed. No mbed Microcontrollers were found' message. I'm trying to do the install on a Windows 7 64-bit machine. Any further insight into what my problem might be?

Also for you, you shouldn't be using this driver, but only the one I linked above. That will also install the serial drivers.

Hi Erik, Your suggestion is for the ST-Link (Nucleo debugger); the link you provide is to upgrade ST-Link firmware. The ST-Link is detected by Windows as ST-Link virtual COM port.

I guess Peter would be interrested by a USB serial driver for the Nucleo itself (not the ST-Link).

Regards.
