Debug messages from the custom board to be displayed on serial terminal

[GK]

Dear Sir,

I am using nrf52832

SDK 15 and softdevice s132.

I have made a custom board using BMD300 module (nrf52832 based module).

I have takem the following pins outside VCC,GND , SWDIO and SWCLK.

I could flash the program to the board using nRFGo Studio and BMD300 DK( from Rigado) by using the following connection pattern

    Rigado BMD300 DK			External/Custom BMD300		    Voltage Source                                                        
	EXT_VTG<-----------------------> VCC <-------------------------->3.3V
	EXT_GND_DETECT <----------------> GND <------------------------->GND
	EXT_SWDIO<----------------------> SWDIO 
	EXT_SWCLK<----------------------->SWCLK 
	GND<------------------------------>GND

I have used NRF_LOG_INFO() function to display the debug messages on serial terminal and it works well  in the BMD300 DK.

I have flashed the same code to custom board.

But the I could NOT get the debug messages displayed on the serial terminal when I run the code on custom board.

Can I use the existing connection (using VCC<GND,SWDIO and SWCLK) to see the messages while running the code on custom board.?

Whether we need to make some changes in sdk_config.h file?

I was trying for this a long time ago.I have checked almost all the related posts , but I could not get a valid working procedure to make it work.

thanking you in advance.

with regards,

Geetha

Tried.But not working.

I have connected the BMD300DK to laptop through USB cable.

The connections are as follows

Laptop <-----USB cable-----> Rigado DK<----SWD/SWCLK/VCC/GND(as mentioned above)-> Custom board(driven by Li-ion battery)

Sorry to hear. I remember that I had similar problems initially and ended up using JLinkRTTClient in a separate terminal window on my Mac. That's the way I'm getting my debugging messages now. What are you using?

I was using serial terminal 'Qcomm'

As stated, I also experience problems in the past with using a terminal. I ended up using the Segger RTT software (JLinkRTTClient.exe on Windows) which is also supported heavily by Nordic.

Also you could look at this or this.
