## 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.
|
|
|
|
### 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).
|
|
|
|
## 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
