Problem with micro_ecc_lib_nrf52.lib in Keil.

[cinder]

I successfully compiled the micro_ecc library, but when I try to compile the project with it, I get an error. Has anyone encountered this? What can be wrong?

How did you compile the micro-ecc library? If you did not compile it using the Makefiles in the SDK, did you see the note in the SDK documentation about compiling micro-ecc backend?

I compile it with Makefile for Keil in nRF5 SDK v14.0.0. Yes, I see this note and followed the instructions step by step. Can you post precompiled libraries or it will not work?

I just want to understand what are the reasons for these problems?

"attributes are not compatible with the provided attributes" - What does it mean?)
