add also cpp as it works fine :-)

What made the shell working? (Might test at home or here if someone returns my board ;-).) |
|
Tried with Olegs board, but I am not able to flash. Not quite sure why - st-flash says the board has 0kb flash... Seems off. |

you could add the c++ stuff in this Makefile as well.
|
@thomaseichinger I still haven't tested, code looks good as for some minor details. Will test tomorrow so we can include it in the release. |

when using an external UART-to-USB converter, these are normally found under /dev/ttyUSB0 under Linux. Can you adjust this?
|
The I also tried different combinations of connecting my TX cable to different RX and TX labeled pins in the nucleo board -> no effect. |

@haukepetersen as mentioned offline, at least on my hardware, using the UART adapter you can only receive while for sending you have to connect to the on-board UART adapter resulting in two shells, one for sending and you can see the result in the other. I tried multiple pin configurations and neither found any errata sheet or similar which sheds some light on this strange behaviour. I will add a hint in the wiki. |

change this to /dev/ttyACM0, and the board is able to communicate out-of-the-box using the integrated USB-UART adapter without any external hw...
|
ok, just found some minor things, will ack once these are fixed. Good job! |
|
and don't forget to squash... |

addressed @haukepetersen's comments, rebased and squashed. |

I changed the wiki in respect of the UART mystery. Travis passed. |

Looking good. ACK and go. |
