Hi,
For my new project, I copied the linker script and Makefile from examples/ble_peripheral/ble_app_uart/pca10040/s132/armgcc to a folder and changed the SDK dir and project dir accordingly.
When I run make, GCC successfully compiles all the sources and places the .o files in the _build/nrf52832_xxaa/. However, it fails at the linking stage. Here are the output of my make -n for last compilation and the final linking stage:

I am unable to figure out why the linker cant find the corresponding files as they are being compiled. I have not changed any source other than the Makefile. The examples in the sdk folder is building fine as well. Kindly help me find the issue
