I have been experimenting with build configuration for the peripheral_uart sample project so I can add DFU. I have had a great deal of difficulty doing this because of unexpected behavior from the nRF Connect SDK plugin for VSCode.
What I have observed is that the nRF Connect plugin adds extra CMake "-D" options to the build configuration which I myself did not add. The reason this is a problem is that these added CMake options are causing the build configuration to fail the next time I edit the build configuration. This is true even if I do not make any changes to the build configuration.
Here are the details:
- OS: Windows 10
- VSCode 1.89.1
- nRF Connect SDK v2.6.0
- Sample Project: peripheral_uart
Steps to reproduce:
- Create an empty directory at C:\XXX\YYY\ZZZ\ (15 character path with client info redacted)
- Open this directory in VSCode.
- Use nRF Connect plugin to create a new project based on peripheral_uart
- Add build configuration, select nrf5340dk_nrf5340_cpuapp as the Board. Leave all other options at their defaults.
- Click blue "Build Configuration" button. Wait for build to finish. (Build will be successful).
- Click "Edit Build Configuration" on the build configuration that just finished building.
- Observe that two Extra CMake arguments were added automatically: -Dhci_ipc_OVERLAY_CONFIG=".;C:/ncs/v2.6.0/nrf/subsys/partition_manager/partition_manager_enabled.conf" -DCACHED_CONF_FILE="c:/XXX/YYY/ZZZ/peripheral_uart/prj.conf"
- Change nothing but click "Build Configuration".
- Observe that build fails.
The TERMINAL will read:

The only workaround I have found is to manually delete the added CMake arguments from the build configuration.
Clearly something is wrong. Could you please have a look and explain what is going on and what I can do about it? Thanks.
