Hi @KooLru ! Thanks for the PR. What is your use case for this change? It seems that NRF52810 and NRF52805 SoCs are not supported by the Arduino core at the moment sandeepmistry/arduino-nRF5#442, sandeepmistry/arduino-nRF5#255

I compile my code (Temperature & Humidity sensor based on MySensors https://github.com/mysensors/MySensors project) with https://github.com/nikolac/arduino-nRF5/tree/nrf52805 branch.

Even though we don't support forked software, I think your PR might be useful. Is there a reason why you added that new flag only to CCFLAGS? Shouldn't it be also present in LINKFLAGS so the linker will use proper versions of standard libs?

By the way, neither of nRF52805, nRF52810, nRF52811, nRF52820 have FPU.
