This is (unfortunately) intended, only a few examples are provided with Makefiles, and only nrf6310/ble_app_hrs with Eclipse project. It should however be quite easy to modify an existing Makefile to make it work with a new project, and also to make a new Eclipse project for it.

A quick notice concerning the new SDK 5.0, there are no eclipse projects in: "C:\Nordic Semiconductor\nRF51 SDK_v5.0.0.34603\Nordic\nrf51822\Board\pca10001".

Could it be that you're looking at an earlier version of the application note. The latest one, version 1.1, is available here: https://www.nordicsemi.com/eng/content/download/16271/261587/file/nAN-29%20%20nRF51%20Development%20with%20GCC%20and%20Eclipse%20Application%20Note%20v1.1.pdf

We're always happy if you accept the answer you find useful, since that clears up the question. :-)

That explains alot. Not exactly what the application note states, but i will try to install that toolchain and try again. Thanks.

Please make sure that you use the supported toolchain from here, and not the CodeSourcery one. The -lnosys library is only part of the CodeSourcery one. See this question for details.

I tried to modify the Makefile.windows to the right directory.

ifeq ($(findstring 86, $(ProgramFiles)), )
	PROGFILES := C:/Users/Administrator/MentorGraphics/Sourcery_CodeBench_Lite_for_ARM_EABI
else
	PROGFILES := C:/Users/Administrator/MentorGraphics/Sourcery_CodeBench_Lite_for_ARM_EABI
endif

GNU_INSTALL_ROOT := $(PROGFILES)
GNU_VERSION := 4.8.1
GNU_PREFIX := arm-none-eabi

@Bluetoothy: Could you make sure you have GNU tool ARM Embedded installed ? It should be located at : C:\Program Files (x86)\GNU Tools ARM Embedded\4.7 2013q1\lib\gcc\arm-none-eabi. if you have the same version 4.7 2013q1.

You can follow the instruction in chapter 1 nAN29 to know which version you have. Please make sure you have modified the Makefile.windows configuration (GNU _INSTALL_ROOT, GNU_VERSION) correctly, matches with your actual installation of GNU tool ARM embedded.

Make for windows can be downloaded from gnuwin32.sourceforge.net/.../make.htm. But you should be fine using cs-make from code sourcery.

Hi Hung,

I updated my post with a stacktrace, furthermore where do i find the GCC ARM make executable, is it included in Sourcery Codebench?

Hi, The build folder is modified a little bit from the time the app note is released.

After you compile the code using gcc ARM (run make.exe in gcc folder), you will have _build folder inside gcc folder instead of directly under ble_app_hrs.
