KL05Z-FRDM debug through USB

I do not even need for my current application but I'm just curious. I'm using ProcessorExpert in my project.


I'm using FreeMaster through the PTB1 and PTB2 pins (UART). I download and debug my code through openSDA in the USB port.


  1. I'm wondering if with this board is possible to use the USB connection for both the debugging sessions AND the puts() or printf() functions (console output) at the same time.
  2. If not, at least I would like to know if it is possible to use the USB-CDC connection for console output (no debugging) and this way I would have the physical uart at PTB1 and PTB2 free for connecting an external board.


I've not been able to do so following the great mcuOnEclipse tutorials


Let me know and have a nice weekend!
