Is it possible to output Jink data output by Printf to UART?

[SHMoon]

hello

The nRF52832 is being reviewed on the nRF52-DK.



nRF52-DK's built-in J-LINK is being used via USB,

The data sent by Printf through virtual COM PORT is monitored on the PC.



The question is, is it possible to output the data sent by nRF52-DK to printf through UART, not USB?

Even with jumpers on the board...

The prerequisite is to use only the J-LINK port, without additional use of the existing UART port.



Thank you.

Yes, see nRF52DK's Virtual COM port documentation. 

In short there's a regular UART interface between the nRF52832 and the debugger (interface MCU). If you need to isolate the nRF52 UART interface from the debugger you need to cut solder bridges 22 to 25. 

This information is also present on the bottom silkscreen of the DK.
