Unable to view RTT or UART logs with ble_app_buttonless_dfu_pca10040_s132

[sschumac]

OS: Ubuntu 19.04

SES: V4.42

Target Hardware: NRF52 DK

SDK Version: 16.0.0

Steps to reproduce:

Update SDK config on application to
NRF_LOG_BACKEND_RTT_ENABLED 1
NRF_LOG_BACKEND_UART_ENABLED 0

I have also tried toggling

NRF_FPRINTF_FLAG_AUTOMATIC_CR_ON_LF_ENABLED

Flash Softdevice S132 (SES flashes with bootloader)
Flash secure bootloader ble (debug or non debug, same result)
Flash ble_app_buttonless_dfu

Application operates normally, can flash new firmware, LEDs behaving as expected. But the debug window does not have any of the expected NRF_LOG_INFO output. 

Connecting via JLink RTT viewer (after closing SES) yields the same result. 
With altering the Log flags in other examples (such as ble_app_blinky), the Debugger Output window yields the correct results. 

Enabling the sdk config flags to use UART, I can connect to the board but no output is displayed.

Hi

What terminal are you using when you try logging your application? I just tried both UART and RTT and got them both to work, only changing the NRF_LOG_BACKEND_UART_ENABLED and NRF_LOG_BACKEND_RTT_ENABLED parameters. Please follow the instructions on the Infocenter to see how to set up and test the example. 

Best regards,

Simon

Thank you, my issue was I had not installed the bootloader settings page correctly after generating my keys. This tutorial was helpful (but based on an older SDK version, but I couldn't find anything that has changed with the process listed)
