HW: 52840DK PCA10056 3.0.1 2023.16
NCS SDK: v2.8.0
I want to test Zephyr's BLE controller instead of the default SoftDevice controller, and the `prj.conf` of ISO_CENTRAL sample is configured as follows:
CONFIG_BT=yCONFIG_LOG=yCONFIG_BT_ISO_CENTRAL=yCONFIG_BT_LL_SW_SPLIT=y
During the build there is an error `undefined reference to `__device_dts_ord_134`. Check the `build/iso_central/zephyr/include/generated/zephyr/devicetree_generated.h` file the ORD 134 corresponds to `/soc/radio@40001000/bt_hci_sdc`, which is SoftDevice controller. The SoftDevice controller should be disable when `CONFIG_BT_LL_SW_SPLIT=y` is set. Please help me clarify the underlying cause and resolve the issue.
Following is the build log
