Hi Amanda,

That was the issue. I added the SD hex also. So now I am getting the debug prints as properly.

Thanks for pointing out that. :+1

Just to confirm, while we pressed 'Build and run' from segger IDE, do the SD and application binary is written into the controller flash?

Hi,

[quote user="jeevan t raj"]Yes, SD is included in our project. I didn't do anything to program SD image separately. How can I do that?. [/quote]

Does the application run with the SD? If so, do you also program the SD image?

Can you give the instructions to try this.

Yes,

Connected main board to nRF52832 DK,

Opened and cleaned the project,

selected build and run from segger IDE,

And it is found the debug prints on the RTT viewer

[quote userid="77782" url="~/f/nordic-q-a/71082/programming-nrf52840-using-nrfconnect-application/292213#292213"]

Do you see any error log while programming with the nRF Connect app? If so, are you able to provide the log?

Hi,

Does the application run with the SD? If so, do you also program the SD image?

[quote user=""]We tried flashing the board using the same setup from the segger IDE and seen that debug prints are getting properly.[/quote]

Do you also get the log from J-Link RTT viewer if you press "build and run"?

Do you see any error log while programming with the nRF Connect app? If so, are you able to provide the log?
