what's difference for nrf52hf_xx and nrf52nf_xx

[Hsu]

Hi Sir,

I'm using nRF52832 + SDK 14.2 for building the OTA DFU function.

As checking the folder "../external/micro-ecc/", for nRF52 family, I found there two difference sub-folder , one is "nrf52nf_xx" and another is "nrf52hf_xx".

I tried to search the info center and document, but no description there.

Could you help to point out what's different for nrf52hf_xx and nrf52nf_xx if I want to build the DFU for nRF52832?

Thanks in advance.

well if you read the release notes as you're urged to do when you download you'll see a note about micro-ecc having both a hard float and soft float build option for the chips which have a hard float and those which don't.

So from there it's an easy guess one of the 'hf' and 'nf' is one and one is the other although it's a bit cryptic. You want the hf one as you have a hardware floating poitn unit.
