Makefile does not produce runnable code, SES does

Question

Hi all I have a project that I developed with SDK 17.0.2 in Segger Embedded Studio. It works well, but now I would like to add a GitHub Runner to compile it every time I push something to my main branch. For that, I want to build a Makefile, so it can run in an Ubuntu environment. I also experimented a bit with cmake. However, both with make and cmake, I get a successful compilation, but the code does not run. The same code compiled in SES and also using embuild.exe works fine. Here is what I tried so far: Build several example projects (e.g. Blinky) with the Makefile that comes with the SDK - that works flawlessly. Compare the emProject-file contents to the contents of my Makefile and linker script - seems to agree. Build and flash using the Makefile, then attach the debugger in SES - I get "Unknown function at 0xfffffffe" (the address changes sometimes when I do something with the Makefile) Load the files from SES and Makefile alternatively into the Programmer application from nRF Connect to compare them. I used some commands to compare the output files, but they appear to have a fundamentally different structure, which makes it hard to compare them (arm-none-eabi-nm -n easyoiler.out > make_symbols.txt and arm-none-eabi-objdump -d easyoiler.out > make_disasm.txt, each command for both and then compare the output) Can you help me to figure this one out? Here is my Makefile: PROJECT_NAME := easyoiler TARGETS := easyoiler OUTPUT_DIRECTORY := _build SDK_ROOT := ../../../../../.. PROJ_DIR := ../../.. $(OUTPUT_DIRECTORY)/easyoiler.out: \ LINKER_SCRIPT := easyoiler_gcc_nrf52.ld # Source files common to all targets SRC_FILES += \ $(SDK_ROOT)/modules/nrfx/mdk/gcc_startup_nrf52.S \

After looking at this for days, of course I find the solution some hours after posting here. 
 The problem lies in this line in the linker script: 
 RAM (rwx) : ORIGIN = 0x20002288, LENGTH = 0xdd90 
 This defines the RAM start and size. Adding these two numbers together: 0x20002288 + 0xdd90 = 0x20010018. However, according to the product specifications https://docs.nordicsemi.com/bundle/ps_nrf52832/page/memory.html the maximum allowed RAM size is 0x20010000. The correct length is calculated as such: 0x20010000 - 0x20002288 = 0xdd78. Correcting this value gives the following line: 
 RAM (rwx) : ORIGIN = 0x20002288, LENGTH = 0xdd78 
 I do not understand why this worked in SES, but it did. And it did not work using a Makefile - as it should.

Makefile does not produce runnable code, SES does
