Hi

Did you check this part:

Virtual Com Port configuration

By default the Virtual Com Port is not enabled. To enable it, you need to close SB2 and SB3 and open SB14 and SB15 solder bridges.

I have an STM32L0538-DISCO board from a seminar a couple years ago and had to do the following to get the serial output to work:

  • Close the SB2 and SB3 solder bridges
  • SB14 and SB15 were already open on mine
  • Update the ST-Link/V2 firmware

Until I updated the STLINK firmware, the USB serial port showed up and connected in my terminal emulator (on a Mac) but no data was received.
