JlinkExe scripts don't check return codes properly. See forum.segger.com/index.php

I wrote a Linux / OS X version of nrfjprog at github.com/.../jlinkpy

I implemented some of the most useful functionality into a shell script, which might be a good starting point. It's here: github.com/.../nrfjprog.sh

If you improve it or write a better one please let me know (or submit a PR to the repo).

openOCD work with Jlink and stlink (or another dongle that supports SWD) only If you apply patches by yourself.

I have tested nRF51 debugging with JLink. Have not tested with OpenOCD. I tested OpenOCD on NXP processor. My page is for multi-platform development with Eclipse/GCC.

Great, but can i use an openocd and jlink to program nrf51822 ?

Go here embeddedsoftdev.blogspot.ca/.../eclipse.html if you wish to work with with Eclipse/GCC on OSX. Works with both Jlink & openOCD. Pure Eclipse project example code also available.

It's not fully tested, but I am just using my version make scripts under macosx All the ld files and Makefile.window/posix come with nRF51 SDK (6.0), and I modified the Makefile.common and added Makefile.template

How do you got it working with the J-Link adapter? I tried latest git version with not much success, how did you edit the tcl file? Thanks

I got stlink v2 usb dongle ($7) and I can program nrf51822 with it easily at my linux. I think it will work for OSX and Windows too!

But you probably need to compile openocd v0.8 with --enable-stlink flag at your distro.

If you want to use JLink adapter, it's also possible with latest openocd patch available at: openocd.zylin.com/ I tried and it's working too! You just need just edit nrf51_stlink.tcl file.

How did you do that? I think I'm going through the same problem

This isn't really something that's officially supported, so there isn't a Nordic-canonical repository. However, I maintain http://github.com/hlnd/nrf51-pure-gcc-setup in my spare time, and usually point people at that if they need this functionality. I'd therefore be happy if you submit pull requests there! :-)

Thank you Ole! That was it ... flashing at 0x0 works.

Next question, between this post and googling, I've found 4 or 5 different sets of makefiles that implement this.

Is there a canonical repository that I should be pulling from? You mention accepting a pull-request, but what repo would I fork from and submit the pull request to?

Thanks!

Ole Morten — Mon, 27 Jan 2014 16:53:05 GMT

The application gets programmed at 0x14000, so if there is no softdevice on the chip, this will not work. If you want to use blinky without a softdevice, you need to make sure that it's flashed at 0x0.

However, there could very well be a bug in the makefiles regarding this. I may be able to check this later, but since it is a spare-time project, I can't guarantee it. I'd be happy to accept a pull request, though.

I also see the error from make due to JLinkExe, and this is why I had a - in front of the JLinkExe define in the Makefile. This causes Make to ignore any errors.

I got JLinkExe installed and working (had to unload the OS X CDC usb drivers to get JLinkExe to see the PCA10001).

I tried flashing the blinky_example, but it doesn't appear to work (at least there are no LEDs blinking).

I used @ahmed's solution (above, thanks!) which generates the same script as found in the github repos mentioned elsewhere.

Here' the results of "make flash":

make: *** [flash] Error 1

I'm not 100% sure why Make reports an error since there's no error message. Could it just be JLinkExe returns 1 for whatever reason?

Also, it's my understanding that I don't need a Softdevice to programmed? It's not set in the makefile, I just have a DEVICE_VARIANT of "xxaa".

Thanks!

Makefile.posix isn't really an official file, it's just something I've made for private use, and hence it is not included in the official zip.

RE: What's the non-Windows way to flash an nRF51882? (POSIX nrfjprog?)

snowball — Mon, 27 Jan 2014 13:10:07 GMT

Thanks, I'll take a look.

BTW: There is no Makefile.posix in the 5.1 SDK ZIP (version 36092), so I just cloned Makefile.windows and edited it. Although I did have to edit lines 9-13 of Makefile.common because the "ifeq ($(OS),Windows_NT)" was commented out and it would always read Makefile.windows.

Ole Morten — Mon, 27 Jan 2014 09:28:42 GMT

I'd recommend you to take a look at this GitHub repository, which contains Makefiles that you can use to flash from either Linux or OS X. They require the J-Link tools to be installed, and be available in your PATH. The GCC path can either be set in Makefile.posix or manually in the project Makefile.

this is what i use in my makefile it works for linux and OS X

There is no posix standard for USB communication unfortunately. The "J" in nrfjprog is because it is talking to a Segger J-Link Lite. J-link makes some OS X binaries Segger J-Link but they are just the minimum for debugging.

I would love to develop on OS X too but most companies just don't have enough users to make those tools worth their time to develop and support. You might have some luck with OpenOCD but I don't have the time to figure that out.
