This seems to work for me as RCP, but I am not pleased with the unsupported status. Were there any other updates? Does it work as intended?

Taking the similar approach as described by the ticket you have referred; I was able to compile the COPROCESSOR sample for NRF5340DK by incorporating the following changes:

1) added following config in the prj.conf

CONFIG_IEEE802154=y

2) Added nrf5340dk_nrf5340_cpuapp.overlay file with following content in ./boards directory

/ {
	chosen {
		zephyr,console = &uart0;
		zephyr,ot-uart = &uart0;
		zephyr,shell-uart = &uart0;
		zephyr,uart-mcumgr = &uart0;
		zephyr,bt-mon-uart = &uart0;
		zephyr,bt-c2h-uart = &uart0;
		zephyr,bt-hci-rpmsg-ipc = &ipc0;
		nordic,802154-spinel-ipc = &ipc0;
		zephyr,ieee802154 = &ieee802154;
	};
};

&ieee802154 {
    status = "okay";
};

3) Added nrf5340dk_nrf5340_cpunet.overlay with following content in ./child_image/802154_rpmsg/boards directory

/ {
	model = "Nordic nRF5340 DK NRF5340 Network";
	    compatible = "nordic,nrf5340-nrf5340-cpunet";

	chosen {
		zephyr,console = &uart0;
		zephyr,shell-uart = &uart0;
		zephyr,uart-mcumgr = &uart0;
		zephyr,bt-mon-uart = &uart0;
		zephyr,bt-c2h-uart = &uart0;
		zephyr,bt-hci-rpmsg-ipc = &ipc0;
		nordic,802154-spinel-ipc = &ipc0;
		zephyr,sram = &sram1;
		zephyr,flash = &flash1;
		zephyr,code-partition = &slot0_partition;
		zephyr,ieee802154 = &ieee802154;
	};
};

&ieee802154 {
	status = "okay";
};

Just putting a snapshot here to show the folder structure and the successful compilation.

If the coprocessor version that I'm trying here isn't setup for nrf5340, where can I find one that is? We would like to use the nrf5340 in a rcp configuration.

Hello Michelle,

As you have mentioned that:

you can build the Thread-CLI sample for both the nrf52840 and nrf5340

you can build the Thread-coprocessor project for the nrf52840

but you are getting errors when building Thread-coprocessor for the nrf5340

The reason is that Thread-CLI sample supports both the nrf52840 as well as nrf5340 based hardware platforms along with few others. However, the NCS Sample Thread-Coprocessor does not support nrf5340 soc based platform. Please see the table below for supported boards, and the sample homepage for more details.

BR,

Naeem

I'm also curious to understand why there is a nrf802154 radio wrapper (*.c/*/h) in the nrf/samples/openthread/coprocesspr but not in the zephyr/samples/net/openthread/coprocessor???
