Hi,
I got some issues with migrating from SDK 14.0.0 to SDK 15.3.0 on a project that was developped from the previous developper. I have already done a lot of migration modifications. The softdevice is 6.1.1.
Problem looks to be about the linker... Sorry for this long detailled message coming now. Hope you will understand it otherwise I will explain if you have questions. I'm a begginer in the field..
STATE :
In our project we have our folder "eclipse_armgcc\Tools" that contains Makefile, Makefile.common, and Makefile.windows, Makefile.posix.
We have our linker file ourProject.ld in the folder "eclipse_armgcc\Project " with one is defined in the makefile LINKER_SCRIPT = ourProject.ld.
In this linker file at the very end there is INCLUDE "nrf5x_common.ld"
I had to replace the Makefile.common that was used before with sdk13 because it called the FILE_LIST.mk which one doesn't exist anymore in sdk 15. So I replaced it with the Makefile.common from the SDK15 folder "nRF5_SDK_15.3.0_59ac345\components\toolchain\gcc", there a lot of changes then I replaced, and I just had inside the line (yellow background) like it was in the previous one :
Here below is my makefile configuration, I have tried two differents configuration which are colored background below (orange and green).

The orange one give me a lot of undefine reference (181 errors).
The green one give me this error :

collect2.exe: error: ld returned 1 exit status
Of course there is no more nrf5x_common.ld in the folder of gcc (TEMPLATE_PATH). It is in the folder mdk now.
So it looks that I should add some libraries paths or something like that in the makefile or modifying something in the Makefile.common... ?
Thank you a lot in advance for your help.
Best regards,
Alan
