DFU over Bluetooth - Modify the Peripheral LBS sample error

[selfcontrol]

Hi,

I have a question regarding the DFU example

---

Board used: nRF7002dk
Toolchain used: v2.6.1
SDK used: v2.6.99-cs2
OS used: Windows 10

---

I was following the process of 'DFU over Bluetooth - Modify the Peripheral LBS sample' from the link below, and encountered a build error starting from step 2a
(I think I saw a similar example in the intermediate course at the academy.)
https://devzone.nordicsemi.com/guides/nrf-connect-sdk-guides/b/software/posts/ncs-dfu#mcetoc_1h90kb1ii2

It is stated that if you use NCS version 2.5.0 or later,

CONFIG_BOOTLOADER_MCUBOOT=y

CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU=y

only need to add the above.

Below is the build failure log.

Please share a solution for this.
(It seems like the example adding MCUBOOT configuration is encountering the same error.)

Hello,

Please use English to describe your issue, as we don't support any other language inside this forum. Briefly state your issue by explaining what you are trying to achieve and where exactly you are facing it. Please use the insert tab to attach the logs so that it is easy for us to go through.

Kind Regards,

Hello, Abhijith.

I apologize, there seems to have been a mistake in the translation process.
I intended to provide the build log through the Insert tab as Code.

but, it didn't work well, so I am providing it in its original form. My goal is to simply add DFU OTA to the BLE_COEX sample code. Therefore, as practice, I followed the DFU over Bluetooth - Modify the Peripheral LBS guide.

The guide mentioned that for NCS version 2.5.0 or later,
you should add the following configurations to prj.conf:

CONFIG_BOOTLOADER_MCUBOOT=y
CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU=y

I only added these two lines and configured the 7002dk board in the BLE Peripheral LBS code.
The build failed, and I am curious about the reason. Is there anything else I need to add?

Thank you.

[Menon]

Hello,

Could you tell me what your build configuration is or to which board you are building this sample? I recommend you follow the Developer Academy tutorial for doing the OTA BLE DFU.

Kind Regards,

Abhijith

Hello again.

The OTA BLE DFU guide provided by the academy follows the same process as the link I mentioned. However, I followed the exact conditions of the Nordic Academy environment once again. I attempted to build the solution project for exercise 3 of lesson 8 in the intermediate course. As a result, the build fails on the nRF7002dk board, which requires OTA, up to this point.

Visual Code - Nordic Connect for VS Code Extension Pack v2023.11.3 Sample: [Academy Intermediate] inter_less8_exer3_solution

First attempt (Academy environment) Toolchains: v2.4.2 (python3.8.2) SDKs: v2.5.2 Build config:

• nrf52840dk_nrf52840
• nrf7002dk_nrf5340_cpuapp
• nrf7002dk_nrf5340_cpuapp_ns
• nrf5340dk_nrf5340_cpuapp_ns

= Only the nrf5340dk_nrf5340_cpuapp_ns build succeeds, as suggested by the Compatible boards setting.

Second attempt (latest version environment) Toolchains: v2.6.1 (python3.9.13) SDKs: v2.6.99-cs2 & v2.7.0_rc1 Build config:

• nrf7002dk_nrf5340_cpuapp
• nrf7002dk_nrf5340_cpuapp_ns
• nrf5340dk_nrf5340_cpuapp_ns

= Similarly, only the nrf5340dk_nrf5340_cpuapp_ns build succeeds, as suggested by the Compatible boards setting.

I tested this on two Windows 10 computers, and the same error occurs. If all other board environments also failed, it would be considered strange, but the build succeeds on the 5340dk_ns.


"If the Python path is not set to 'Toolchain_folder\opt\bin\python.exe' for someone else, and it's running as a local Python without installed pip modules, the build for nRF5340dk_nrf5340_cpuapp_ns will also fail.

Build failure message: from cryptography.hazmat.~ ImportError: DLL load failed while importing _rust"

The failure reasons on the 7002dk board include "RAM overflowed by 250184 bytes" and a few others.

This board is the official nRF7002 DK board, not a custom-made one, and the sample is also an official sample. I am wondering if this error is occurring only for me.

If possible, could you test the BLE OTA process?

Thank you.

[Menon]

Hello,

That's strange. I will try to test this here and get back to you by Monday.

Kind regards,
Abhijith
