Hi, 

Is this related to your issue : https://github.com/NordicSemiconductor/pc-nrfutil/issues/222

Please make sure you are using Python 2.7 not 3.x

Hi ,

Please send me the python 2.7 which you is working at your end. I tried with 2.7.7 but it showing pip is not recognized as internal or external command.

Also when giving command as 

python get-pip.py install

then 
python: can't open file 'get-pip.py': [Errno 2] No such file or directory  

this error occurs.

Also no pip is there at scripts folder when I checked.

So please help me.


regards,
 Archana

Please check and make sure you still have your Makefile.windows is still with correct encoding. I attached here my Makefile.windows. Also please change the path to remove any space. avoid "37. Nordic", do "37_Nordic" instead. 

I don't see that complain of Makefile.windows missing in your first screenshot earlier. Please try on a fresh copy of the SDK.

Ok, 

where is attchment of Makefile.windows, I didn't get in your reply.

I added the micro-ecc-master under external/micro-ecc folder downloaded from github
