Make and Keil not working together on DFU OTA example

[Juan Gomez]

Hello Nordic team!

I'm following this tutorial from Nordic to do DFU OTA: https://devzone.nordicsemi.com/guides/short-range-guides/b/software-development-kit/posts/getting-started-with-nordics-secure-dfu-bootloader

I was able to compile and test the code with SDK17 and SES, but for different reasons, I had to move to Keil and SDK12(as in the example).

When doing step B1a I get the following error: 

Checking my x86 files there's no folder like that, but I barely know about Make. Also, it's rare because before downloading Kel I did see it and B1a was able to compile. I suppose I need to change something in the Make file? 

I would really appreciate all the help you can give me and thanks a lot in advance :)

Hi,

The error indicates that you have not specified the correct path etc to your ARMGCC installation in <SDK>\components\toolchain\gcc\Makefile.windows. This must be updated to the path that matches your system. (Note that GCC is used here to build the micro-ecc library regardless of which toolchain your use to build your application).
