Hello,
I am currently trying to run this ble_secure_bootloader. I am using SES V5.68 with the nRF52840 SoC and I am using nRF5 SDK version 14.2.0. I have also adjusted it to be buttonless instead of using a button to enter DFU mode. Using J-Flash Lite, I flashed my merged Bootloader+SoftDevice to my device and then successfully sent a packaged zip file over Bluetooth from my phone to the device using the nRF Connect for mobile. The package was sent successfully but nothing happened, which is why I enabled NRF_LOG in the sdk_config.h, to get a better idea on why nothing happened. This resulted in quite a lot of errors, most of them problems with inclusions. After including all of them, I was left with these errors.

We managed to fix the first three errors ("section...") by editing the flash_placement file and adjusting how much memory some of the sections had. Now I am left with these errors:

I am unsure on how to fix them, as I have included the path to the library in Segger and even added both the nrf_balloc.c and nrf_balloc.h to my project just in case.
I have also attached a zip file with the project if that helps :)
Any help is appreaciated!
