SDK 2.6.0 cmake error: CONFIG_BT_RPMSG has been renamed to CONFIG_BT_HCI_IPC

[Dan]

Just upgraded to NRF v 2.6.0 (Mac OS; VS Code). Our code previous built and ran successfully on our custom board with v 2.5.0 of the SDK.

Now we get the following error which breaks the build process, and it is unclear how to resolve it (e.g. setting CONFIG_BT_RPMSG=n in prj.conf just produces a different error).

CMake Error at /opt/nordic/ncs/v2.6.0/zephyr/drivers/bluetooth/hci/CMakeLists.txt:5 (message):
CONFIG_BT_RPMSG has been renamed to CONFIG_BT_HCI_IPC

Kindly advise. Thanks! Dan.

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!

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.

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.

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
• CMakeLists.txt: https://github.com/nrfconnect/sdk-nrf/commit/053408845f4a351f0af8253b91bedc1d811f69e9#diff-e2a911094a594e6eaa6d1ea8625cd108692a9c90cde60838b254573c94960fc0L12-R12
