Stepping through nRF Mesh Bootloader code in Segger Embedded Studio

[Thomas-Brilliant]

Has anyone been able to successfully setup a Segger Embedded Studio project to step through the Bootloader included in the nRF5 SDK for Mesh (https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.meshsdk.v3.2.0/md_mesh_bootloader_README.html)?

I'm looking at adding some functionality in the bootloader to verify that the application firmware is not corrupted (via CRC32 check) before attempting to launch it. However, it seems fairly challenging to debug the bootloader without any sort of capability to step through the instructions in Segger. Am I missing something?

Hi Thomas, 

I have put a request to our R&D team to produce the SES project for the bootloader. I will let you know if we have any update on this. 
Note that you can do debugging using GDB with the gcc project. But I would assume you need to set the optimization level to no optimization.

Any news on this? I am wanting to look into the bootloader code and debug it also.

Hi, 
Attached is an SES project for nRF52840 bootloader SDK v4.x. It has not been thoroughly tested but it should work. 

Please replace original main.c with the attached one.
