Hi,
I am encountering the following build error with the BLE peripheral example after migrating from NCS 2.7.0 to 2.9.0 and when CONFIG_BT_LL_SW_SPLIT=y is set in prj.conf, and I am using a nRF52 DK.
/toolchains/b8efef2ad5/Cellar/cmake/3.21.0/bin/cmake -E true
/opt/nordic/ncs/toolchains/b8efef2ad5/opt/zephyr-sdk/arm-zephyr-eabi/bin/../lib/gcc/arm-zephyr-eabi/12.2.0/../../../../arm-zephyr-eabi/bin/ld.bfd: zephyr/subsys/bluetooth/host/libsubsys__bluetooth__host.a(hci_core.c.obj):(.data.bt_dev+0x16c): undefined reference to `__device_dts_ord_110'
collect2: error: ld returned 1 exit status
The example seems to build fine with 2.7.0 using the zephyr LL software stack, so I am wondering if there are changes that I will need to make either in prj.conf or the dts file to get the application to build correctly.
I was also looking at the change log for Zephyr 3.7.0 which is included in NCS 2.6.0, and it looks like they went through a redesign of the zephyr HCI driver and the compiler is now looking for a zephyr,bt-hci chosen property. Therefore, I have added zephyr,bt-hci = &bt_hci_controller to my device tree file, but I ended up getting the same error and with the DEVICE_NAME_GET macro.
Any help would be greatly appreciated! I understand that the soft-device stack is preferable, but I would like to stick with the Zephyr stack for now for the flash space benefits.
