## Overview
|
|
|
|
The Nucleo-L152RE is a board from ST's Nucleo family supporting a ARM
|
|
Cortex-M3 STM32L152RE microcontroller with 80KiB of RAM and 512KiB of Flash.

## Supported Toolchains
|
|
|
|
For using the Nucleo-L152RE board we strongly recommend the usage of the [GNU
|
|
Tools for ARM Embedded Processors](https://launchpad.net/gcc-arm-embedded)
|
|
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](https://github.com/RIOT-OS/RIOT/wiki/OpenOCD).
|
|
|
|
### 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:
|
|
```
|
|
make BOARD=nucleo-l152re PROGRAMMER=cpy2remed flash
|
|
```
|
|
@note This PROGRAMMER was tested using ST-LINK firmware 2.37.26. Firmware updates
|
|
could be found on [this STM webpage](https://www.st.com/en/development-tools/stsw-link007.html).
|
|
|
|
## 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
|
|
|
|
2. done
