nrf_crypto_rng_pca10040 examples can not find micro_ecc_lib_nrf52.a

[Conan_y]

I did nothing to run this example but it failed. I don’t know what to do to make this example run, thank you

Hi.

This is because the micro-ecc library is not distributed with the SDK. In order to use it you will have to install and enable it yourself. This link explains how to do this.

Best regards,

thaks,i install the gnumake ,git ,micro_ecc,but i still failed when i run the build_all.bat

The error make (e=2) is that the system cannot find the file specified.

The problem might be that it does not find the mkdir command. What happens if your try to write mkdir in your terminal? 

It might also be a problem with the path. You need to set correct path in <SDK>\components\toolchain\gcc\Makefile.windows for your installation of GCC.

Best regards,

Marte
