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;

...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 :
/*****************************

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