nrfjprog for ARM cpu (Raspberry Pi 3)

[kazuph]

Hi, I tried the above tools(nrfjprog) on the Raspberry Pi 3.

But, I saw the error shown below.

pi@raspberrypi:~$ ls | grep nRF5x nRF5x-Command-Line-Tools_8_5_0_Linux-i386.tar nRF5x-Command-Line-Tools_8_5_0_Linux-x86_64.tar

$ tar xvf nRF5x-Command-Line-Tools_8_5_0_Linux-i386.tar ./ ./nrfjprog/ ./nrfjprog/nrfjprog_release_notes.txt ./nrfjprog/libnrfjprogdll.so.8.5.0 ...

$ ./nrfjprog/nrfjprog -bash: ./nrfjprog/nrfjprog: cannot execute binary file: Exec format error

$ rm -rf nrfjprog && tar xvf nRF5x-Command-Line-Tools_8_5_0_Linux-x86_64.tar ...

$ ./nrfjprog/nrfjprog -bash: ./nrfjprog/nrfjprog: cannot execute binary file: Exec format error

Where is the nrfjprog build for ARM?

Thank you,

Hi,

Unfortunately we do not have builds of nrfjprog for ARM.

As an alternative you can look into J-Link tools that support ARM linux, for nRF51 the user made nrfjprog.sh exists.

Best regards,

I also stumbled on this when investigating which tools will work with my Raspberry Pi3.

Have I understood this right:

- There is a build  of the J-Link tools for Arm (see "J-Link Software and Documentation pack for Linux ARM systems" in your above link). I downloaded it and managed to connect to my nRF52 DK (PCA10040) without problems. I run JLinkExe for this.

- nrfjprog is using the J-Link tools somehow. Is it using JLinkExe, or the library files?

- There needs to be a build for nrfjprog for ARM to run this on the Raspberry Pi. Are the sources for nrfjprog closed? No chance of building it myself for the Raspberry Pi?

Hi,

nrfjprog is closed source and we do not have nrfjprog for ARM-based CPUs.

Your best option here is to use the JLinkExe program (as you already do) that segger provides.

Note that there are forks available of the nrfjprog.sh (see link in the original post) that has added functionality for the nRF52-series devices. See the different forks here: github.com/.../network

Cheers,
