Logs in Bootloader and Main Application

[Szymon]

Environment:

Segger Embedded Studio

nRF52840

S140

Windows

nRF 5 SDK 17

Hi,

I'm developing a device for a small side project. I need to get logs in both the bootloader and main appllication.

I successfully got logs in DFU when I only flashed the secure_bootloader_debug example and got logs in the main application if I flashed the application by itself.

However when I merged the bootloader with the application, it appeared that I only got logs in the application.

I've searched this forum and found a similar problem here.

I tried adding these lines to SEGGER_RTT.c

static char __attribute__((section(".rtt_ac_up"))) _acUpBuffer [BUFFER_SIZE_UP];

static char __attribute__((section(".rtt_ac_down"))) _acDownBuffer[BUFFER_SIZE_DOWN];

SEGGER_RTT_CB __attribute__((section(".rtt_segger"))) _SEGGER_RTT;

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

static char __attribute__((section(".rtt_ac_up"))) _acUpBuffer  [BUFFER_SIZE_UP];
static char __attribute__((section(".rtt_ac_down"))) _acDownBuffer[BUFFER_SIZE_DOWN];
SEGGER_RTT_CB __attribute__((section(".rtt_segger"))) _SEGGER_RTT;

However I get a compile Error in Segger when I want to compile secure_bootloader_debug from the examples in the SDK again:

Is this the correct way of doing this? I was unable to find any other problems like mine on this forum and a solution to my above problem. Thanks for any guidance/ help.
