nRF5340: Build Error During Power Measurement in Low Power Mode (SDK v2.6.1)

[sasikumar p]

Hello,

I’m working on an nRF5340 project and trying to measure power consumption in low power mode using SDK v2.6.1. I followed the instructions provided on your website   but I encountered a build error.

Details:

• SDK Version: v2.6.1
• Custom Board : nrf5340-nrf7002

Build Configuration in vs code:  board = nrf7002dk-nrf5340-cpuapp-ns

Reference :

https://docs.nordicsemi.com/bundle/ncs-1.6.0/page/zephyr/reference/power_management/index.html

Steps I followed:
1. Set up the SDK environment as per the documentation.
2. Configured the project for low power mode.
3. Attempted to build the project using the provided instructions.

Troubleshooting steps I’ve tried:
- Rechecked the configuration.
- Cleaned and rebuilt the project.
- Ensured all dependencies were correctly installed.

Despite these steps, the error persists. Could you please assist me in resolving this issue?

Error:

FATAL ERROR: command exited with status 1: 'C:\ncs\toolchains\cf2149caf2\opt\bin\cmake.EXE' --build 'c:\ncs\v2.6.1\Waggle_Sensors\application\Node_1\build'

Thank you.

Hi,

Can you copy the text from the full log, and paste it into a Insert->Code box?

Also, please include the full build log.

I understand, but unfortunately, I wasn't able to add it successfully, and I also couldn't paste the log here

[Sigurd Hellesvik]

The docs you are following are from nRF Connect SDK 1.6.0.

Instead, use the latest docs. The API has changed since.

[sasikumar p]

I encountered a build issue when attempting to use the pm_state_set() API in our custom project. I have attached the error log for your reference. Interestingly, when I tested the same API in the latency sample file, it worked without any issues.

Could you please help me resolve this issue.

Do you get any Kconfig override warnings in your build log?

[Shanmugam]

Getting this error / warning in the proj.conf .

Hi Shanmuga, 

Are you working on the same project with Sasikumar ? If not please create a new ticket. 
Please check if any of the dependencies is not match. You can check that in the .config file in the build folder.
