Issue with Enabling MCUboot on Custom Board with nRF5340

[Yashaswini S]

Hello,

I am working on a custom Agora board that includes a BT40 module with an nRF5340 MCU. I am trying to enable the MCUboot bootloader by setting CONFIG_BOOTLOADER_MCUBOOT=y in my prj.conf file. However, I encounter an error during the initial configuration stage.

Here are the details of my setup:

• Custom Agora board with BT40 module
• nRF5340 MCU
• Using Nordic SDK version 2.7.0
• The bootloader demo works on the nRF52840 development board using the Nordic course

Error Message:

Could anyone provide guidance on how to resolve this issue or suggest additional configurations that might be required for the nRF5340 MCU on a custom board?

Thank you!

Hi,

I amo not able to see exactly what the error is, but it the path is long which can cause problems on windows. I sit possible to rename and move things so that you make "C:/Users/YASHAWS/Agora/xyleminc-wwno-gnode-009afda753b5" much shorter? Do you still see the same error after that?

[Yashaswini S]

Hi,

Thank for the suggestion. I'll try to shorten the path.

But the Error is -FAILED: build.ninja
C:\ncs\toolchains\ce3b5ff664\opt\bin\cmake.exe --regenerate-during-build -SC:\Users\YASHAWS\Agora\xyleminc-wwno-gnode-009afda753b5 -BC:\Users\YASHAWS\Agora\xyleminc-wwno-gnode-009afda753b5\build_4

This is the main issue is facing and after enabling the CONFIG_BOOTLOADER_MCUBOOT=y on prj.conf file.

Hi,

I tried by creating byown private and public key and adding with to existing project.

Do you any reference for the adding the keys to existing project.since after adding the keys also not reflcting in the project.

and also issue still persists.

Thank you

[Einar Thorsrud]

Hi,

Adding keys are described under Enabling a bootloader chain using sysbuild. For older SDK versions or if you are using the parent-child image, you need to follow the instructions under Enabling a bootloader chain using child and parent images (deprecated).

If you face issues, can you elaborate on what you are doing an in what way it does not work?

[Yashaswini S]

Hi,

We have tried in nRF5340 DK and everything works as per the Nordic exercise: Single slot and Dual slot methods for DFU over UART.Exercise 1 - DFU over UART - Nordic Developer Academy

But when we have a nRF5340 custom board with different or updated board files, following the same procedure gives different results.

Firmware loads but doesn’t reflect in board. Also slot swap doesn’t work.

Thank you

[Einar Thorsrud]

Hi,

I see. We need to know more about what is happening (logging/debug information).

1. What is the difference when you do it on a DK and you custom board?
2. How do you perform the DFU (using MCUmgr or nRF connect on a phone or similar?
   1. Do you do it in the same way?
   2. Can you share logs?
3. Can you enable logging and share logs from the nRF?
4. What else have you found by testing/debugging?

[Yashaswini S]

Hi,

1. The difference between the dk and custom board will be on dts file and peripherals.

2. I am using mcumgr command line tool to perform DFU. I have used same commands mentioned in . Exercise 1 - DFU over UART - Nordic Developer Academy By using this i am able do the DFU for nRF5340dk board and new firmware upgrade sucessfully.

I will share the commands which used to update new firmware using mcumgr commands.

For the custom board, I am using the same commands to update the new firmware.

1.To update new firmware for custom board, do I need to change anything in command?

2.while doing, sometimes I will face error called NMP_timeout.

What could be the reason for this and how to solve this?

Thank you

     

[Einar Thorsrud]

Hi,

I see. NMP timeout indicate UART communication problems. Are you using the UART for something else, or perhaps you have a serial terminal open for the same port at the same time?

[Yashaswini S]

Hi,

I'm not using the UART for different communication and also the not using same port at a time.

[Einar Thorsrud]

Hi,

I am sorry for the delay. As you get a timeout it seems that there is no communication, as mentionned earlier. Which UART pins are you using on the custom board, and how have you configured your devicetree accordingly? And have you connected the correct pins to your USB-UART interface?

[Yashaswini S]

Hi,

I have crosschecked the pin details on devicetree and everything is mapped according to the datasheet.

I am having another issue, that I mentioned earlier like dual swap method is not reflecting in the hardware, which I shared the commands also in previous discussion. we have tried

1. We already tried taking the NRF5340DK_nrf5340 folder and copying it to an Agora_bt40 folder, then replaced all references to nrf5340dk_nrf5340 with Agora_bt40. 
2. We took the elements of the agora_bt40.dts file which are different from the standard nRf5340DK and reflected those changes in the agora_bt40_common.dtsi file. But the response is same.
3. Also, the slot partitions changed in agora_bt40_common.dtsi wrt agora_bt40.dts.
4. We made the agora_bt40.dts to agora_bt40.overlay and tried. 

Still the LED blink bin file loading through bootloader doesn’t reflect in the hardware.

These are thing which we tried but the successfully new bin file is loading but once i press the reset after that, changes are not reflecting in the hardware.

But in the dk board it works successfully, with the custom board the issue is happening.

Thank you

Do you get UART working for other use cases, such as logging? With the same instance? If not, it could be good to verify that the UART pins used in the genrated zephyr.dts in the build folder points to the actual UART pins on your hardware.

I am a bit confused about this, as from what I am able to see you are not able to communicate at all with the custom board over UART with mcumgr. So is this with a DK, or did I misunderstand?

After the firmware is transvered it needs to be activated. This can be done permanently or a single time ("test"). This must be configured before the reset, and then the bootloader will swap in the new image upon boot. If there are issues here, perhaps you can share exactly what you are doing (specifying board and step by step instrutions), and in what way it does not work?
