IEEE 802.15.4 support on NXP RW612

[phamelin]

Hello,

I've noticed recents commits related to IEEE 802.15.4 on the NXP RW612 in the zephyr and hal_nxp repositories. However, according to the doc, IEEE 802.15.4 is still not officialy supported by this board/MCU in Zephyr 4.1.0.

Is anyone aware of the current status? Is the documentation just not up-to-date, or is this is still a work in progress?

Thank you.

@andrei-menzopol @axelnxp could you comment on that?

Hello @phamelin

IEEE 802.15.4 is supported for RW612 in Zephyr 4.1.0 release. We will add IEEE 802.15.4 in "Supported features" section of https://docs.zephyrproject.org/latest/boards/nxp/frdm_rw612/doc/index.html page.

Thank you @Ritesh-nxp.

I was finally able to compile RW612 OpenThread samples. At first, I was looking for some nxp/rw/ieee802154 driver that I could enable in the device tree, but after some time I found a NXP OpenThread RCP host driver enabled through CONFIG_HDLC_RCP_IF=y. Maybe it could be a good idea to either add this to the FRDM_RW612 config, or document this config on the board support page.
