No serial print in PuTTY or nRF Terminal

[Asbjorn Bjorkkjar]

Hi,

I attend the introduction course for the nRF's, and I am at Lession 3. The task is to print 'Hello World' to the device, using Serial Port and COMx. I have made the files I need, and I use the 'printk'-function in the main.c. I have tried to print both in PuTTY and in nRF Terminal without seeing it work out. The PuTTY-window is totally blank after I have build and flashed. The nRF Terminal only gives a line with 'Connected via Serial Port with settings COM7 115200 8n1 rtscts:off'. 

I have checked that COM7 is the right port, and I use 115200 for baud rate. 

Do you know a solution?

I am getting the same error as Asbjorn. Here's what I have:

• I am using a Mac + nrf5340. 
• Testing with Blinky app and have selected nrf5340dk_nrf5340_cpuapp in the build config file
• Connected to VCOM1 port with 115200 8n1 rtscts:off config
• LED on the board is flashing which means the flashing process is working
• I don't see the logs however..

Please let me know if I am missing something. I can try putty next to see if that helps.

Hi,

Did you figure it out?

If not, here is a list of things to try:

• Check the other VCOM port.
• Check with Putty, Termite, or any other terminal. For figuring out the COM to use, you can use the nrfjprog command line utility (part of nRF Command Line Tools) with the --com option.
• Do the MSDDisable, as explained in a previous post in this thread.
• Install the latest J-Link Software and Documentation Pack from SEGGER, as well as update the interface MCU firmware on the DK with the newest SEGGER firmware (for instance using J-Link Configurator, which is part of the J-Link Software and Documentation Pack.)
• If all else fails, what is the DK version?
