What is 7 ? can anyone understand this language ? its not even a sentence. Why is it so hard for people to create guide for other people and not other machines ? these steps where useless for me. Too many assumptions, not clear.

Hello, Andrejs.

I can not understand 7. paragraph? Could you put some pictures of configuration how to do it ?

Here is some screens in attachment, showing how to create linked folder and how to exclude unnecessary files from build. In my case I put the SDK files (Source and Include) in my Eclipse workspace in folder \lib\Nordic_5.1

And why I can not choose target processor in C/C++ Builder -> Settings (attached picture)

Looks like you chose the wrong type of project when you created it. Make sure you created it like this: File -> New -> C project Enter project name. In the window that appears in "Project type:" field select line "Empty Project" in folder "Executable". Then in right field "Toolchains:" select Cross ARM GCC. THen press next -> next -> select toolchain name "GNU Tools for ARM Embedded Processors (arm-none-eabi-gcc)" and path to toolchain for example "C:\Program Files\GNU Tools ARM Embedded\4.8 2013q4\bin"

Linked folder.rar

You can add all SDK source and include files to your project using linked folders and exclude from build all unnecessary files as I described in my post above in paragraph 7. Here is sample eclipse project: https://devzone.nordicsemi.com/index.php/discussions?controller=attachment&task=getFile&tmpl=component&id=632

I add by import src, https://www.dropbox.com/s/2q8396dfs2qwfzw/Screenshot%202014-03-30%2019.55.29.png however, still same error?

You need to add the simple_uart.c file to the project.

I can't build in eclipse

see screen here www.dropbox.com/.../Screenshot 2014-03-29 13.33.58.png

My include is setup without problem, if I did not using retarget.c, it builds without problem

Suggest adding flags: specs=nano.specs

Suggest improving the gcc_nrf51_common.ld and add a FLASH size check like this: ASSERT(LENGTH(FLASH) >= (SIZEOF(.text) + SIZEOF(.ARM.extab) + SIZEOF(.ARM.exidx)+ SIZEOF(.data)), "region FLASH overflowed")

Thanks Nikita. I ran through the ble_app_hrs example and nAN-29 a while back. Everything worked well. In this case I don't have a preexisting project, so instead of importing, I create a C Project->Make Project. I also had to deselect the option in the project setup to use the default location and specify where the source of my new project is (this project is a modified version of ble_app_lbs). I've done that and gotten it to compile using the existing Makefile, now I just have to finish following the instructions in nAN29 again for setting up debugging via the JLINK.

Thanks again.

to Richard von Lehe This steps is exceptionally for creating pure eclipse project. If you want to create eclipse project that uses makefile than you can find that in [url=http://www.nordicsemi.com/eng/nordic/download_resource/18792/6/73843444]nAN29[/url]. You can find example configured eclipse project here: \nRF51 SDK_v5.1.0.36092\Nordic\nrf51822\Board\nrf6310\s110\ble_app_hrs If you using GNU Tools for ARM Embedded Processors version 4.8 2013q4 or higher than you need to fix makefile from SDK - add flag -Wno-unused-local-typedefs to compiler flags: ...

Compiler flags

CFLAGS += -mcpu=$(CPU) -mthumb -mabi=aapcs -D$(DEVICE) -D$(BOARD) -D$(TARGET_CHIP) --std=gnu99 CFLAGS += -Wall -Werror -Wno-unused-local-typedefs CFLAGS += -mfloat-abi=soft ...

How would you modify this project setup so that you use a preexisting Makefile?

I'd love to try! is there a guide for this plugin? Has anyone used it with Nordic micros? The goal is to use and debug with Nordic micros; I have seen solutions for other MFGs though.

Would love to see this. I tried gnuarmeclipse, but no love. Maybe I didn't whack the right moles.

Can you publish your formula?

RE: Creating a new project under Eclipse from scratch

RK — Tue, 14 Jan 2014 03:00:40 GMT

There's a plugin for Eclipse designed for ARM, google gnuarmeclipse, which is a good start for setting up a project. It adds tools to create the image and size it. I have a template for a blinky example project which configures all the right settings but haven't published it yet.

With that plugin you can create a native Eclipse project which works very well and debugs. That same plugin has what I think is a better JLink debugger too.

Thanks very much for the update!

RE: Creating a new project under Eclipse from scratch

Gilson — Tue, 07 Jan 2014 18:50:37 GMT

This looks like what I need. It is similar to some of the steps I already took. thanks so much, looks promising! Have a great day!

AN29 does not show project creation from scratch. I don't see the tool set used etc. but thanks for your reply. I appreciate your time.

RE: Creating a new project under Eclipse from scratch

Nikita — Tue, 07 Jan 2014 18:21:00 GMT

Check this: nAN-29 It shows example makefile-project. If you want to create a project from scratch, you will need to do this:

Install Eclipse Kepler with GNU ARM Eclipse Plug-in.
Do what was written in nAN-29 in 1 Required tools and 1.1 Setting up Eclipse.
Create new empty C project -> Executable -> Cross ARM GCC press next -> next -> select toolchain name "GNU Tools for ARM Embedded Processors (arm-none-eabi-gcc)" and path to toolchain for example "C:\Program Files\GNU Tools ARM Embedded\4.8 2013q4\bin"
Add all files from the example project folder to your eclipse project folder i.e. for ble_app_proximity copy files : nRF51 SDK_v5.1.0.36092\Nordic\nrf51822\Board\pca10001\s110\ble_app_proximity\ble_bondmngr_cfg.h nRF51 SDK_v5.1.0.36092\Nordic\nrf51822\Board\pca10001\s110\ble_app_proximity\main.c nRF51 SDK_v5.1.0.36092\Nordic\nrf51822\Board\pca10001\s110\ble_app_proximity\pstorage_platform.h
Create new folder in the eclipse project folder with "startup" name and put in there files: nRF51 SDK_v5.1.0.36092\Nordic\nrf51822\Source\templates\system_nrf51.c nRF51 SDK_v5.1.0.36092\Nordic\nrf51822\Source\templates\gcc\gcc_startup_nrf51.S change file extension from small .s to big .S
Create new folder in the eclipse project folder with "linker" name and put in there files: nRF51 SDK_v5.1.0.36092\Nordic\nrf51822\Source\templates\gcc\gcc_nrf51_common.ld and one more linker file with the name according to your needs gcc_nrf51_{1}_{2}.ld: where {1}: blank

for projects without softdevice s110 - for projects with s110 softdevice s120 - for projects with s210 softdevice and {2}: xxaa - for chips with xxAA at the end (i.e. NRF51822-QFAA-GC) xxab - for chips with xxAB at the end

Add new linked folder to project with Source and Include folders from SDK. 7.1. Go to the linked Include folder and do Resource Configurations -> Exclude from build for either s110 or s120 folder depending on what softdevice you are planning to use. For ble_app_proximity exclude s120 folder. 7.2. Go to the Source folder and do Resource Configurations -> Exclude from build for all the files in there that are not needed for the project. For ble_app_proximity check out what files are needed from existing keil example project: nRF51 SDK_v5.1.0.36092\Nordic\nrf51822\Board\pca10001\s110\ble_app_proximity\arm\ble_app_proximity.uvproj
Go to the project properties -> C/C++ Builder -> Settings: 8.1. In target processor select ARM family: cortex-m0 8.2. In Optimization uncheck all flags and set optimization level to none (-O0). Later you can change this settings. 8.3. In Cross ARM C Compiller -> Preprocessor add defined symbols: NRF51 DEBUG NRF51822_QFAA_GC DEBUG_NRF_USER BLE_STACK_SUPPORT_REQD BOARD_PCA10001 Change them according to your board. 8.4. In Cross ARM C Compiller -> Includes add all required include paths. For ble_app_proximity it will be: "${workspace_loc:/${ProjName}}" "${workspace_loc:/${ProjName}/Nordic/Include}" "${workspace_loc:/${ProjName}/Nordic/Include/app_common}" "${workspace_loc:/${ProjName}/Nordic/Include/ble}" "${workspace_loc:/${ProjName}/Nordic/Include/ble/ble_services}" "${workspace_loc:/${ProjName}/Nordic/Include/boards}" "${workspace_loc:/${ProjName}/Nordic/Include/ext_sensors}" "${workspace_loc:/${ProjName}/Nordic/Include/gcc}" "${workspace_loc:/${ProjName}/Nordic/Include/s110}" "${workspace_loc:/${ProjName}/Nordic/Include/sd_common}" 8.5. In Cross ARM C Compiller -> Optimization select Language standard to GNU ISO C99 (-std=gnu99). 8.6. In Cross ARM C Compiller -> Miscellaneous add to the Other compiler flags -Wno-unused-local-typedefs -mabi=aapcs -mfloat-abi=soft. 8.7. In Cross ARM C Linker -> General add main linker file. For ble_app_proximity it will be: "${workspace_loc:/${ProjName}/linker/gcc_nrf51_s110_xxaa.ld}" And uncheck all flags. 8.8. In Cross ARM C Linker -> Libraries add Library search path to the gcc_nrf51_common.ld file. "${workspace_loc:/${ProjName}/linker}" Uncheck all flags and add to the Other linker flags -mabi=aapcs.

UPD: I fogot a few things in 8.7 and 8.8 and added them now.

UPD2:I added sample eclipse project: Eclipse_workspace.rar

Hi Gil,

Did you have a look at the nAN29 application note? It's the instruction on working with GCC and the nRF51 SDK. From that, it's not too hard to create a new project under Eclipse for the nRF51. Let me know if you have any trouble.
