How can i view NRF_LOG_DEBUG()???

[kevin seo]

Hello.

I want to see NRF_LOG_DEBUG ("some") through the terminal. When I compile, I get the following error:


What should I set or change?

MCU : nRF52840
compiler: IAR
Project: secure_bootloader(DFU)

Hi Kevin, 

Please use the project under <nRF5_SDK>\examples\dfu\secure_bootloader\pca10056_ble_debug to view the debug info without any changes.

no. I'm trying to debug through NRF_LOG_DEBUG because I don't know anything about the secure_bootloader project.

Hi Kevin,

As Amanda mentioned, you need to use different project.

because the your working project fit for release version which means it doesn't have enough memory space to include debug symbol.

Try "pca10056_ble_debug" this project.

The SDK supports Jlink RTT by default.

So you need to use Jlink RTT Viwer which it installed with Segger Jlink tool.
