When using this board with RIOT, set the BOARD variable to nucleo-l152re in your Makefile. If you follow the standard RIOT project structure, your Makefile should look like this:

# name of your application
APPLICATION = hello-world

# Change this to your board if you want to build for a different board
BOARD ?= nucleo-l152re

# This has to be the absolute path to the RIOT base directory:
RIOTBASE ?= $(CURDIR)/RIOT

include $(RIOTBASE)/Makefile.include

Flashing the Board

A detailed description about the flashing process can be found on the guides page. The board name for the Nucleo-L152RE is nucleo-l152re.

Using UART

Using the UART isn’t too stable right now. For some using the USB interface just works, others have to connect the USB interface to a active USB hub and others again can only transmit over the USB interface and receive using an external UART adapter.

Connecting an external UART adapter

connect your usb tty to the st-link header as marked
