#### Description
<!--

-->
Got some working code for my old stm32f0discovery board. We tried to upload to our new b-l072z board, but there is no output in my terminal. I got the gps code, from 

[code](https://github.com/smartuni/riot-bloon-balloon-control/blob/master/code/gps_data.c)

When there is an interrupt from the gps it sends data to the terminal, which works on my stm32f0discovery board. With some changes I tried to flash it to my b-l072z board but I don't get any output in my terminal.

I connected my gps module and my usart breakoutboard to flash the board on the two usart peripherals of the b-l072z. On my stm32f0discovery it worked but on the b-l072z it doesnt'.

#### Steps to reproduce the issue
<!--
Try to describe as precisely as possible here the steps required to reproduce
the issue. Here you can also describe your hardware configuration, the network
setup, etc.
-->
Flash my code to the board is compiling but there is no output and no errors.
#### Expected results
<!--
Example: The gnrc_networking application builds on samr21-xpro.
-->
GPS values will be printed.
#### Actual results
<!--
Please paste or specifically describe the actual output.
-->
Just the init prints but there are no measurements.
#### Versions
<!--
Operating system: Mac OSX, Linux, Vagrant VM
Build environment: GCC, CLang versions (you can run the following command from
the RIOT base directory: make print-versions).
-->

<!-- Thanks for contributing! -->
