nRF5340: about the sample 'IPC Service' build

RE: nRF5340: about the sample 'IPC Service' build

My overlay was put in the project folder, it's strange that the build system can not find it:

(In the folder 'boards', only have .conf files, without nrf5340dk_nrf5340_cpuapp.overlay here. According to the rule of device tree precedence, the build system should go to the project folder to find the icmsg.overlay)

I think it is just a mistake. I removed openamp in prj.conf for RPMSG and the project still builds without openamp.

Something is wrong with your setup.

Mine says in the log

-- Found BOARD.dts: C:/ncs/v2.5.0/zephyr/boards/arm/nrf5340dk_nrf5340/nrf5340dk_nrf5340_cpuapp.dts

and your says in the log

-- Found BOARD.dts: C:/ncs/v2.5.0/zephyr/boards/arm/nrf5340dk_nrf5340/nrf5340dk_nrf5340_cpuapp.dts
-- Found devicetree overlay: .overlay
<command-line>: fatal error: .overlay: No such file or directory

Where is the build finding .overlay in your build?

Hi Susheel,

Thank you for the reply.
I followed your suggestion, deleted the build directory, and did the pristine build with the below command in the 'nRF Connect' terminal in VS code:

west build --build-dir c:/ncs/v2.5.0/nrf/samples/ipc/ipc_service/build c:/ncs/v2.5.0/nrf/samples/ipc/ipc_service --pristine --board nrf5340dk_nrf5340_cpuapp --no-sysbuild -- -DNCS_TOOLCHAIN_VERSION=NONE -DCONF_FILE=c:/ncs/v2.5.0/nrf/samples/ipc/ipc_service/prj_icmsg.conf -DEXTRA_CONF_FILE=overlay-cpuapp-sending.conf -DBOARD_ROOT=c:/ncs/v2.5.0/nrf/samples/ipc/ipc_service

But the same error occurs:

In addition, I'm still confused about RPMSG/ICMSG, why in the configuration of RPMSG has 'CONFIG_OPENAMP=y

IPC is the service native from Zephyr RTOS and OPENAMP is on the high level. For RPMSG and OPENAMP they still need to use IPC.

Regarding the build errors, I recommend you to do a prestine build with the configurations you suggested. I was able to see the error you mentioned when I built the bidirectional sample first and changed the command to build it with uni directional. It failed. After removing the build directory and doing the prestine build again, it worked. Please give it a try.
