Supported Toolchains

For using the st-nucleo-l1 board we strongly recommend the usage of the GNU Tools for ARM Embedded Processors toolchain.

OpenOCD

Please use an OpenOCD version checked out after Jan. 26th 2015. Building instructions can be found here.

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

  1. connect your usb tty to the st-link header as marked st-link-header
  2. done
