Hi Satish

We will need logging information from the nRF52840 DK, not the computers build/flash log. It says a debug session is ongoing, but it doesn't seem like you've opened a terminal with logging from the nRF52 device. 

Please check out the "Testing and debugging an application" section in the nRF Connect SDK documentation to see how to connect to a serial terminal (PuTTY for example) and debug your application specifically.

Best regards,

Simon

Hi Simonr ,

I have solver earlier issue , related to setup issue , JLINK version suppose to use little older 82c . 

Btw,  I would like to check the  HW rx window has opened correctly or not , so below are the configuration are used by mynewt os ,Here we suppose to give pin number . 

what are the gpio pin are present on nrf52840dk ? i can see pin are present with the name p0.0 , p0.1 ......p0.11 .

How i can map these pin to number like below?

p0.0    =   0

p0.1    =  1 so ....

is there any mapping to those pin name p0 , p1 ? 

Thanks,

Satish
