Supported Toolchains
For using the Nucleo-L152RE board we strongly recommend the usage of the GNU Tools for ARM Embedded Processors toolchain.
Flashing the device
Flashing the Board Using OpenOCD
Please use an OpenOCD version checked out after Jan. 26th 2015. Building instructions can be found here.
Flashing the Board Using ST-LINK Removable Media
On-board ST-LINK programmer provides via composite USB device removable media. Copying the HEX file causes reprogramming of the board. This task could be performed manually; however, the cpy2remed (copy to removable media) PROGRAMMER script does this automatically. To program board in this manner, use the command:
- Note
- This PROGRAMMER was tested using ST-LINK firmware 2.37.26. Firmware updates could be found on this STM webpage.
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
- done
