Can nRF52820 Support IEEE-802.15.4

[HuangYubin]

Trying to using IEEE-802.15.4 on nRF52820 with SDK-17.1.0, Librarie 802_15_4/raw/802_15_4_lib_gcc.a.

nRF52820 not support FPU so set -mfloat-abi=soft in Makefile

Encounter "802_15_4_lib_gcc.a(sys_ringbuffer.o) uses VFP register arguments, _build/nrf52820_xxaa.out does not"  someting like that.

Looks like 802_15_4_lib_gcc.a is compiled with FPU enabled.

Can nRF52820 support 802.15.4, where to get No-FPU librarie? 

I'm using 802.15.4 MAC only, not in Zigbee.

Can it support on nRF52833?

[Sigurd]

The 802.15.4 library that comes with SDK-17.1.0 is written for nRF52840, and isn't tested with nRF52833, and hence, we can't guarantee that this precompiled library works with nRF52833.

Alternatively, you can look at the nRF-IEEE-802.15.4-radio-driver, it supports nRF52833, but note that this library only have the PHY layer, and not the MAC layer.
