Problems with the Nucleo STM32-F401RE

I’m using the board STM32F401RE with Windows 10 on a VMware machine on macOS (Because with macOS and Zerynth r2.0.6 I had problems). When I virtualise Zerynth says:“Insufficient disk space on current disk. Insert another disk and type continue. . .”. It seems there’s something on the board that occupies the flash of the board entirely or maybe something else like troubles with the reset button. I have no idea.

I provided to uninstall and reinstall all the drivers and to update the board’s firmware with another PC on real Windows 10, but I still have the same problem: not enough space during the virtualisation process and so I’m unable to use the board.
There’re only 8KB on the NODE removable device.

Hi luigiferrettino,

The issue with the Nucleo F401RE for virtualizing or uplinking the device should regard the configuration of the onboard jumpers, more precisely the JP5.

This jumper has 3 pins (E3V - Vin - U5V) and permits to select the source of the power supply choosing between external power supply (E5V) and ST-LINK VBUS power supply (power over usb cable - U5V).

To power-up the mcu with the USB cable you have to connect the Vin pin and the U5V pin as shown in the picture.

Let me know if this can help you :slight_smile:
