SDK 2.6.0 cmake error: CONFIG_BT_RPMSG has been renamed to CONFIG_BT_HCI_IPC

RE: SDK 2.6.0 cmake error: CONFIG_BT_RPMSG has been renamed to CONFIG_BT_HCI_IPC

Try looking at

choice BT_HCI_BUS_TYPE
	default BT_RPMSG if BT
endchoice

in your Kconfig.defconfig.

You do not set

CONFIG_BT_RPMSG

explicity but indirectly with those line.

Replace it by

choice BT_HCI_BUS_TYPE
	default BT_HCI_IPC if BT
endchoice

works for me.

Hopes that can help.

Hi Dan,

The current migration guide should clarify what needs to be done as the generic change. I will report to the team.

Here is the diff https://github.com/nrfconnect/sdk-nrf/commit/053408845f4a351f0af8253b91bedc1d811f69e9#diff-ed87fd10afb9df8f9ad29b4c2d08ed80d2aa16677b17dd4d67be68eefbfe1f22, includes the changes on samples. You can refer to any sample or application to do what you need to modify.

It showcases the following two changes (apart of KConfig change) for matter:

The folder has been renamed from child_image/hci_rpmsg to child_image/hci_ipc

Amanda Hsieh - any guidance from the Nordic team? Our board is a custom board using the NRF5340. We don't anywhere explicitly set the CONFIG_BT_RPMSG (so it must be getting included somewhere) and as far as we can tell includes all use 2.6.0 code paths. Is there any other information we can provide to help you help us? Thanks! Dan.

I was able to fix it. My project has scripts based on the dk board definitions, so I update it (overwritten & adapt) to the new 2.6.0.
If you are selecting a board from list it may be including other pre-configured boards from nordic and maybe that is causing your define.

kammutierspule - thanks for your suggestion and for sharing that you also are running into this issue. Were you able to successfully resolve it?

I checked my board definition files directory and nowhere am I defining or referencing CONFIG_BT_RPMSG. And when I trace through which board config files and .dts files are getting included, they are all coming from the 2.6.0 version of the code tree.

So I am still at a loss of what to try next. Appreciate any guidance/help!

Hi Dan, I'm facing the same problem,
I believe you are using the board definitions from a previous sdk (eg some sdk example)
looks on the new Kconfig.defconfig
you may want to update to new board definitions
ncs/v2.6.0/zephyr/boards/arm/*

Could you share the complete log via Insert -> code?

Hi Amanda - yes - I saw that, but it's not clear to me how to fix it so it can build. I am not setting these configs anywhere in my code - they are getting included upstream (our application is a Matter application) and I don't know where/what I should change to make it build. What do you recommend?

Hi,

Due to the Easter holidays in Norway, we are less staffed than usual. You can expect a delayed answer.

The HCI implementation for both the Host and the Controller sides has been renamed for the IPC transport. The CONFIG_BT_RPMSG Kconfig option is now CONFIG_BT_HCI_IPC, and the zephyr,bt-hci-rpmsg-ipc Devicetree chosen is now zephyr,bt-hci-ipc. The existing sample has also been renamed, from samples/bluetooth/hci_rpmsg to samples/bluetooth/hci_ipc. (GitHub #64391)

See the https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/releases/migration-guide-3.6.html#bluetooth

Amanda H.
