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...

...copying shared history...

...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

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.

[SL06]

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

Had to use sudo and python3.

[SL06]

After the install command, I had the following warning , but the rest of the processs seems OK.

SLMini-I5-172:pc-nrfutil-master slareau$ sudo python3 setup.py install
