Hi, from BLE_setup_test_nrf54l15_cpuapp, you are including the wrong dtsi.

you can see that in the original nrf54l15dk board, it points to the "nrf54l_05_10_15_cpuapp_common.dtsi" which is equivalent to your
"nrf54l_15_cpuapp_common"

So, change it to this

Again, please make sure that you are using the correct board "BLE_setup_test/nrf54l15/cpuapp".

Your west command should look something like this

"west build --build-dir c:/Ticket/351347/peripheral_lbs/build_1 c:/Ticket/351347/peripheral_lbs --pristine --board BLE_setup_test/nrf54l15/cpuapp -- -DBOARD_ROOT=c:/ticket/351347/my_boards"

Please follow the tutorial step by step next time when creating a custom board, then change/add what you need.

Hi Danie,

I'm following the same steps from the link you referred to for creating the board files. However, I'm unable to build the files successfully.

I've shared the following files:

BLE_setup_test.zip – This contains the board files folder.
peripheral_lbs.zip – This is the sample firmware I'm trying to build.
Build error doc.docx – This document shows the error I'm getting after running west build.

Could you please check and let me know what might be causing the issue?

Hi Haritha, I'm a bit confused on your set up
What is the name of you custom board?

From your build log

west build --build-dir c:/Haritha/Github/BLE_mcu_rsl_merge/build c:/Haritha/Github/BLE_mcu_rsl_merge --pristine --board nrf54l15dk/nrf54l15/cpuapp -- -DBOARD_ROOT="c:/my_boards"

It seems like your custom board name is nrf54l15dk/nrf54l15/cpuapp ? Please rename it if that's the case since that name is already taken for the actual nrf54L15DK.

Does the BLE_setup_test folder sit in "c:/my_boards" from above? Is BLE_setup_test_nrf54l15_cpuapp your custom board?
If so, the board name would be BLE_setup_test/nrf54l15/cpuapp and -DBOARD_ROOT should point to the BLE_setup_test folder

Please follow Exercise 2 - Custom board for a multi-core & TF-M capable SoC/SiP - Nordic Developer Academy
to create a custom board for nrf54l15

If you still experience difficulties, please also send over your intended board root folder ("c:/my_boards")

Hi Danie,

Please check below provided information

devzone.nordicsemi.com/.../BLE_5F00_setup_5F00_test.zip devzone.nordicsemi.com/.../7266.peripheral_5F00_lbs.zip

devzone.nordicsemi.com/.../Build-error-doc.docx

I am trying to build custom board files using the BLE_setup_test and peripheral_lbs sample code. However, I’m getting errors during the build process.

I am using visual studio Version: 1.104.0 (user setup)

If your build succeeds when you select the board target as nrf54l15dk/nrf54l15/cpuapp in VS Code with nRF Connect, it means:

The nRF Connect SDK installation includes all required SoC support files for the official nrf54l15dk board.
The folder zephyr/soc/arm/nordic_nrf/nrf54l/ and its files (Kconfig.soc, DTSI, headers, etc.) exist and are correctly referenced.
The board configuration, CMake, and Kconfig for nrf54l15dk are complete and compatible with the SDK version you have.
The build system can find and use the correct SoC and board files, so all required symbols (like CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC) are set.

Reason your custom board fails:

Your custom board folder or SoC support files are missing, incomplete, or not correctly referenced.
The build system cannot find the required SoC files for your custom board, but it can for the official nrf54l15dk.

zephyr/soc/arm/nordic_nrf/nrf54l/ SoC support files must needed for build custom files.........?

The board target selected is nrf54l15de/nrf54l15/cpuapp and a custom board configuration. The sample code built successfully without any errors.

Is this information Help you for resolve this issue.......?

Thanks

Haritha

Hi, unfortunately we don't do teams call. Can you send over the build folder? I will take a look.

Hi Danie,

Teams call possible...?

I will show you how I am configuring bord file GPIO & Oscillator.... etc.

Thanks & regards

Haritha.

Hi, it seems like you are missing the device in the device tree that your are trying to access
"C:/ncs/v3.1.0/zephyr/include/zephyr/device.h:96:41: error: '__device_dts_ord_31' undeclared (first use in this function); did you mean '__device_dts_ord_1'?"

Can you please find out what node 31 (from devicetree_generated.h) then check if it's disabled in <build>/zephyr/zephyr.dts.

More information about that process can be found here Troubleshooting devicetree

Also are you using an internal RC oscillator? And can you show me how you are configuring it?

I am using NRF54L15 BLE MCU. Compiling C:\ncs\v3.1.0\nrf\samples\bluetooth\peripheral_lbs file building with new created board files. I am getting above mention errors.
