DFU SDK v16 on Mac OS X

[SL06]

Hi,  I am trying to get DFU from SDK16 working on my Mac.(Mac Os Mojave).  I am following the instruction on https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_nrf5_v16.0.0%2Fble_sdk_app_dfu_bootloader.html

I have tried first to build the micro-eco library by clicking on the build_all.bat file and got the following errors from the Terminal.app:

/**************************

SLMini-I5-172:~ slareau$ /Users/slareau/nrf52_development/nRF5_SDK_16/external/micro-ecc/build_all.bat ; exit;

Saving session...

...saving history...truncating history files...

...completed.

/*************************

To solve that step, I have navigate to the micro.ecc folder in terminal.  I have open the build_all.bat file in TexEdit ,  copy and paste the following command directly in Terminal.app  

git clone https://github.com/kmackay/micro-ecc.git

and then

make -C nrf52hf_armgcc/armgcc      // I believe that  the only one that I need for my project

This work perfectly. 

I have tried to generate a public and private key with nrf_util.  I have done that without problem in SDK14.3

nrf_util ask me to upgrade to the latest version with I did. 

In Terminal.app  I have navigate to the dfu folder where I want the key to be generated and type the command :

nrfutil keys generate priv.perm

I have the following problems :

and the package seems to be install correctly.

Here a creenshoot of the folder 

At this point, I am not sure what is the next step.

[SL06]

I have just notice that nrfutil come with the libusb package.  have tried to reinstall nrfutil with the following command as stated in the nrfutil v1.3 document find on the web:When installing on macOS, you might get an error about the Python module six. In this case, enter the following command instead

pip install --ignore-installed six nrfutil

When generating the private key, I still have the same error : 

OSError: dlopen(libusb-1.0.dylib, 6): image not found

[Marjeris Romero]

Hi,

Can you try to reinstall nrfutil from sources (using pip)?

Best regards,

Marjeris

[SL06]

Following the instruction, I have download tnrfutil installation pkg from Github.

In Terminal.app I navigate to the folder and type : pip install -r requirements.txt

Listing says that all requierent were satisfied, except this line :

   Ignoring antlib: markers 'sys_platform == "win32"' don't match your environment

I  assume that Ok, its a Mac.

I have tried to run nrf_util without installation and this append:

The // OSError: dlopen(libusb-1.0.dylib, 6): image not found // is the one I got previously - see beginning of the post 

To install nrfutil, the python setup.py install does not work - it try to install the program with python 2.7 framework.  I had to use python3 setup.py install

and then got  the error at the end of a long list:

error: [Errno 13] Permission denied: '/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/easy-install.pth'

I had to use the command: sudo python3 setup.py install,  and it work.

I have then tried to run the command : pyinstaller nrfutil.spec

and the command was not found.

***

SLMini-I5-172:pc-nrfutil-master slareau$ pyinstaller nrfutil.spec

-bash: pyinstaller: command not found

*****

Typing the command: nrfutil -- help    give and a long list ending by the following error:

OSError: dlopen(libusb-1.0.dylib, 6): image not found

Could it be that a file is misplace during the installation ? Please look at the screenshot.

Specific installation instruction for OsX would be nice since command differ from what is in the instruction.

Had to use sudo and python3.

[Marjeris Romero]

Hi,

The installation instructions are general for all OS, but if you have multiple versions of Python installed in your system you need to check that you are using the right version. In the Installing instructions for nRFutil it's stated that you should use Python 3.7 or later. 

The sudo requirement is probably because of local settings / install permissions settings in your computer.

Could you double check your python enviroment for pip install using command 'pip --version'? It looks like you are using the python 2 enviroment instead of python 3. Try 'pip3' instead.

Did you run 'pip install -U setuptools' before installing the requirements?

Have you installed pyinstaller?

Best regards,

Marjeris

[SL06]

Hi Marjeris,

i ran pip3 install -U setuptools and as you can see, it says Requirement already up-to-date..

Notice that I also running python3.7, as indicate earlier in the post.   Also, NrfUtils 6.0.0 was working before the latest upgrade, few days ago.

_____

SLMini-I5-172:~ slareau$ pip3 install -U setuptools

Requirement already up-to-date: setuptools in /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages (45.1.0)

________

Pip -- version   give me: 

_______

SLMini-I5-172:~ slareau$ pip --version

pip 19.3.1 from /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/pip (python 3.7)

________

I am using pip and python 3.7 for programming currently without problems.

I have tried to download and go back to nrfutil version 6.0.0 and it don't work anymore - same error as V6.0.1.  

I would like to erase everything and restart from scratch but I am not sure what file was installed. I don't want to accidentally delete file that are used with my other program that use python

[SL06]

I believe that I have found the solution.  I have just follow my idea above and found the pip uninstall command.

What I have done  is:

in mac terminal.app, uninstall nrfutil by typing:

1.  pip3 uninstall nrfutil   //  use pip3 to specify python3, if permission denied, use sudo before and enter password.

2.  retype:  pip3 uninstall nrfutil   // make sure that all the file are gone.  Delete those remaining manually if needed.

3.  Follow the installation instruction from : https://infocenter.nordicsemi.com/pdf/nrfutil_v1.7.pdf,  but replace all installation pip  command by: sudo pip 3  .  This will avoid permission denied error and install the file in python3 folders.   You also have to replace python commands by: python3.

I have used the installation procedure in section from the above document without difficulty :  2.2 Installing from sources.  :  Typing:   nrfutil --help    confirm that the program is now functional.

I have tried the following command to create a self-contained executable version of nrfutil, without success. :  pyinstaller nrfutil.spec

The installation log indicate that several missing module that could not be import.  The command have generate an non-functional installation package.  Here a partial list of the errors.  At this point I will just use the nrfutil with terminal command and report if I have problems later.  I want to use the DFU utilities.

Hi,

 Have you installed pyinstaller using 'pip3 install pyinstaller' ? Did you verify the version using 'pyinstaller --version'?

Maybe these links could be of help?
