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

[Archana Fugare]

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 follow this to install pip: 

• Securely Download get-pip.py [1]

• Run python get-pip.py. [2] This will install or upgrade pip. Additionally, it will install setuptoolsand wheel if they’re not installed already.

Hi,

Thanks.

My OTA succussfully completed.

But I used ready libraray instead of creating.it.

I want to create it so please help me.

The MinGW/GNU make not working for creating libraray in external- micro ecc folder.

D:\37. Nordic\52DK\nRF5_SDK_15.3.0_59ac345\external\micro-ecc\nrf52nf_armgcc\armgcc this is the path of my folder.

when I give this path and make command then libraray not created.

Please share me MinGW or GNU make tool if anybody have.

Please check folder C:\Program Files (x86)\GNU Tools ARM Embedded to see which version of gcc you have there.

And update the file in \SDKv15.3\components\toolchain\gcc\Makefile.windows to match with your gcc version and path. 

[Archana Fugare]

Hi, 

Thanks.

Please help me, how to update that file 

The gcc version is 5.4.1 20160919 

I edited the Makefile.windows by open in worpad and write my gcc version and file path:

After updating also same error:

[Hung Bui]

Update it like this: 

GNU_INSTALL_ROOT := C:/Program Files (x86)/GNU Tools ARM Embedded/5.4 2016q3/bin/

[Archana Fugare]

Hi,

Same error occur even I updated the Makefile.windows file.

Saying no Makefile.windows file found.

I open that file as wordpad.

I tried this way, please help me or send me the MinGW.

regards,

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. 

[Archana Fugare]

Ok, 

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

[Archana Fugare]

I tried with both sdk version 15.2.0 and 15.3.0 for both getting same error

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

[Archana Fugare]
