Arduino for STM32

Hello everyone

I dusted off my Nucleo F411RE board today to get it working again with STM32 Core. I can upload via the onboard ST-Link (after the firmware update) and Mass Storage. My question is where does Serial.print output go? There is a serial port (/dev/cu.XXXX) but no output appears there.

What am I missing?

Hi kenjutsu

I don't remember which dev format it is on Mac, anyway it is simple to find which one it is.
List all /dev/* with the board disconnected then with the board connected and check the diff.
The port should also be listed in Arduino, if not there is a issue.
Which Arduino IDE version you used ? Did you select the right baudrate?

Thank you for the reply,

Under /dev are two entries related to the F411RE:

• /dev/tty.usbmodemFA13123

• /dev/cu.usbmodemFA13123

Under Arduino -> Tools I have the following settings: /dev/cu.usbmodemFA13123 is automatically selected and is also the only option available. The same happens under CoolTerm.

I create a new Blink example with the following in setup(): and in loop(): I upload to the board and start the Serial Monitor and nothing is displayed. The same for CoolTerm. The connection to the serial port is fine. The ST-Link V2.1 is at firmware V2J37M26

The Nucleo F411RE has no real USB connector.
The USB connector available is for the STLink and the VCP com port created forward the data of a real USART.

So simply set USB support to None and then this should be ok.

Thank you, that did the trick

Hello,

I've got the same problem about not seeing anything in the serial com port.
Setting USB support to None didn't help me.
I'm using a stm32 nucleo f411re and the latest version of ardiuno IDE on windows.
Anyone willing to help ?
