ERROR WHEN CREATE BLE ADVERTISING NRF54L15 CUSTOM BOARD

[Nguyen Kha Duong]

Hi everyone,
I tried to create BLE ad for customboard nrf54l15, but it doesn't seem to work.
I upload my code in the attached file:

when I buil project, I have an error:

 "undefined reference to `__device_dts_ord_92'"

I don't know to configure that.

Can you help me solution for this, please?

Thank for that,

yes,
I have configured it before but still get error.

Could you upload the .config file in <build>/<your app/sample name>/zephyr/  ?

[Nguyen Kha Duong]

Hi, 

I upload the file project in HERE.

In the project, I just initialized the ble protocol in the main function (I use sample code BLE ADS). When I build the program, I get an error.
"
c:/ncs/toolchains/b620d30767/opt/zephyr-sdk/arm-zephyr-eabi/bin/../lib/gcc/arm-zephyr-eabi/12.2.0/../../../../arm-zephyr-eabi/bin/ld.bfd.exe: zephyr/subsys/bluetooth/host/libsubsys__bluetooth__host.a(hci_core.c.obj):(.data.bt_dev+0x134): undefined reference to `__device_dts_ord_92'
"
As far as I know, the number 92 is  "/soc/peripheral@50000000/radio@8a000/bt_hci_sdc " ( I searched in the library:  <build>/zephyr/include/generated/zephyr/devicetree_generated.h ) 

Besides, I have enabled bt_hci sdc (status = "okay") in the device tree file. But when I run it still shows the same error.

Can you help me with this problem, please?

Hi!

I had a look at the project.

Try to apply these changes.

1)

in nrf54l15_custom_nrf54l15_cpuapp.dts

&clock {
	status = "okay";
};

&grtc {
	owned-channels = <0 1 2 3 4 5 6 7 8 9 10 11>;
	/* Channels 7-11 reserved for Zero Latency IRQs, 3-4 for FLPR */
	child-owned-channels = <3 4 7 8 9 10 11>;
	status = "okay";
};

&lfxo {
	load-capacitors = "internal";
	load-capacitance-femtofarad = <15500>;
};

&hfxo {
	load-capacitors = "internal";
	load-capacitance-femtofarad = <15000>;
};

and in Kconfig.defconfig , replace the content with this:

if BOARD_NRF54L15_CUSTOM_NRF54L15_CPUAPP

config BT_CTLR
	default BT

config ROM_START_OFFSET
	default 0x800 if BOOTLOADER_MCUBOOT

endif # BOARD_NRF54L15_CUSTOM_NRF54L15_CPUAPP
