NRF_LOG , print not working on putty prompt

[ratnakar1978]

Hi ,

   I am using NINA-B301 EVK having nRF52480 core chipset. I am trying to flash all USB, UART examples to see the log or print on the putty prompt but I am not able to see any log even after setting all configurations on putty.

I had checked in the forum that need to enable DTR but did not  observe the same in any USBD, UART related applications.

I tried following applications

USB CDC ACM

USB MSC

Temeprature

USBD

USBD UART

But I am not able to see any print / log on putty prompt.

Can anybody help me in this.

Hi Ratnakar,

Have you followed the documentation on the third party site?

Have you tried the standard UART sample?

Hi Martin,

      Yes, I am referring all documents related to EVK and chipset from Ublox. I am able to flash program on EVK and seeing that LED on EVK working fine. But I am not able to see the NRF_LOG from EVK back to Host PC on USB port.

So flashing works fine only here issue is with the UART communication from EVK to host PC on USB port.

I had checked in debug and output window in Segger Embedded Studio but I am not seeing any NRF_LOG in these windows. I am using Ubuntu Host PC .

•  What is your COM port? Are you sure that you are using the correct one?

  Can you try on a windows machine? I just want to check whether the issue is on the computer side or the nRF side.
