Undefined Reference to _device_dts_ord_82

[Adam W]

Hi, Im setting up a project for custom board based on NRF54L15. I followed a tutorial on creating custom board and it works fine. Now i want to add BLE functionality similiar to those in peripheral_lbs example, but when i try to enable it like this in prj.conf:

CONFIG_BT_PERIPHERAL=y

i get a Undefined Reference to _device_dts_ord_82. Same happens when i try to call bt_enable in my source file. Im uploading my zephyr.dts file below. Thanks for help!

Full error message: zephyr/subsys/bluetooth/host/libsubsys__bluetooth__host.a(hci_core.c.obj):(.data.bt_dev+0x170): undefined reference to `__device_dts_ord_82'

Hello,

The error indicates that the bluetooth controller is not enabled. Does your application enable CONFIG_BT and does your board file enable CONFIG_BT_CTRL when this symbol is selected as here: https://github.com/zephyrproject-rtos/zephyr/blob/d651a29606395d80abe754ddbd12d73157f6c675/boards/nordic/nrf54l15dk/Kconfig.defconfig#L19?

Best regards,

Yes, my board file enables CONFIG_BT_CTRL as in file you linked, and my application have CONFIG_BT=y in prj.conf

I was able to reproduce the linker error when creating a custom board through the extension. It turns out that the board symbol being checked in Kconfig.defconfig is not valid. Please check the .config file for your application and update the symbol to match your board.
