Redirecting stdout to linux console

[Olivier Scalbert]

Hello !

I have just received the Evaluation Kit nRF51822-EK. I succeed to compile link and load the blinking leds example from my Linux box. I modify the example to use the two switches, and I am able to use gdb to monitor some variables. But I have a question ! If I put a "printf" inside the code, how can I display it in a console ? or in gdb ? Is it possible without connected another cable between the board and my linux box ?

Thanks for your help !

The only way to do receive such prints is to use a separate UART terminal to connect to the USB-to-UART device that the Evaluation Kit exposes, for example minicom or similar. In addition, you need some small wrapper functions in the nRF51 application. You may have use in taking a look at this example.

Does this still work with the new SDK? There's app_uart.c now (maybe it was there before but it didn't exist before in my mind, so let's assume it didn't). Can we do the same trick with that? I assume we can, but has anyone done it?

I'm also running into memory problems with printf in my code, and I think not having this bit right is the root cause.
