hf means that the chip have hardware support for floating point operations (Cortex M4F CPU). nf is only used for nRF52810 ICs.

I have this same problem. I'm trying to compile and link the dfu\secure_bootloader for my nRF52832 project. I am using the linker script from the SDK15 with only minor edits to take care of directory structure and location of main.c, etc. All the other linker scripts I have run have worked perfectly. When i got to micro-ecc I wasn't sure if my board is nRF52832hf or nRF52832nf (I have nRF52 DK). Also, I will be putting this in lots of nRF52832s manufactured in China and I have no idea if these are nf or hf. Anyway, I get the same message either way.

After some investigation I traced this problem to a small error in my copied make file. I omitted the .out in the (OUTPUT_DIRECTORY) field. After fixing that, no more message. The board seems to have floating support.

What are you trying to link? Are you using the Makefiles from our SDK to allow GCC to take care of the linking?
