nRF SDK 2.9.2: BT_CTLR_RX_BUFFERS unsatisfied dependencies: BT_LL_SW_SPLIT (=n)

[Leiser]

I need help with this issue. I'm updating the code from SDK 2.4.2 to SDK 2.9.2. I had change the device tree to HWM2 and I'm using sysbuild.

The build log is showing this warning:

warning: BT_CTLR_RX_BUFFERS (defined at subsys/bluetooth\controller/Kconfig:225) was assigned the
value '10' but got the value ''. Check these unsatisfied dependencies: BT_LL_SW_SPLIT (=n). See
docs.zephyrproject.org/.../kconfig.html and/or look up
BT_CTLR_RX_BUFFERS in the menuconfig/guiconfig interface. The Application Development Primer,
Setting Configuration Values, and Kconfig - Tips and Best Practices sections of the manual might be
helpful too.

After I had set CONFIG_BT_LL_SW_SPLIT in HCI_IPC_CONF I got more errors:

After a day trying to figure out what I'm missing I decided to use the hello world sample with nrf5340dk and I got the same error. Below I copied the log.

Here my test code using the hello_world sample.

Hi, 

This looks like very similar issue like the one that is mentioned and discussed here. Can you try the --no-sysbuild with the build command and see if that helps?
