You can use the J-Link tools directly if you want to do operations on the chips from Raspberry Pi, they provide a Linux ARM version of the J-Link software pack.

Please count me as one who would like to use nrfjprog on my RPi tester. We chose to use the RPi for our tester for its cost and size. Other chip manufacturers have provided command line utils for the RPi (ARM). You should too! Thanks.

Did you check if you have the pc-ble-driver directory in your cloned repo and that it actually contains any files? Git does not clone linked repos automatically unless you pass the '--recursive' argument.

I'm currently not aware of any roadmaps to add support for ARM platforms to nrfjprog, I think this will depend on if the J-Link SDK will be supported on ARM.

Yes, I checked out pc-ble-driver-py @ v0.11.4 and found those issues building from source.

Are there any plans in your team or in your roadmap to support these nordic tools on ARM platforms?

In my opinion, it would be a really nice-to-have feature for the community of developers working with your great nRF5 chips.

I'm not sure exactly what cause the cmake error, looks like it cannot find the path or something. Did you clone the pc-ble-driver repository into the pc-ble-driver-py directory, and checkout the required commit/version?

You are correct that nrfutil is not supported on ARM platforms, however the nrfjprog dependency can be removed from the pc-ble-driver-py code if you make sure that the correct connectivity firmware is flashed to the chip before running the applications. It should only be used to check and flash the correct connectivity firmware.

The next problem that rises:

Traceback (most recent call last):

    load_entry_point('nrfutil==5.1.0', 'console_scripts', 'nrfutil')()

    raise NordicSemiException('nrfjprog not installed')
pc_ble_driver_py.exceptions.NordicSemiException: nrfjprog not installed

and the question: how could I use nrfutil in the RPi if there is no support of nrfjprog for that platform?

Thank you again for your support.

Hi Jørgen,

Thank for your support.

I am trying to build pc-ble-driver-py (v0.11.4) in the RPi, but I am facing the following issue:

[ 74%] Built target pc_ble_driver_shared_sd_api_v2

[ 75%] Linking C shared module outdir/_pc_ble_driver_sd_api_v2.so

Error copying directory from "/home/pi/pc-ble-driver-py/pc-ble-driver/cmake/../hex/SD_API_V2" to "/home/pi/pc-ble-driver-py/python/pc_ble_driver_py/hex/SD_API_V2".

Makefile:83: recipe for target 'all' failed

make: *** [all] Error 2

As far as I can see, those folder are existing but in lower case.

Do you have in mind to provide working versions of these useful nRF tools for the RPi?

Best regards,

Javier

Hi,

Compiling for Raspberry Pi have been done for an old version, see this blog post. I have not tested this myself, and I'm not aware if this have been done on later versions, however I do not see why it should not work.

Can you describe your process for compiling and what issues you are facing? Are you trying to build pc-ble-driver, or pc-ble-driver-py?

Best regards,
Jørgen
