Radio Test sample: Custom .overlay in /boards/ not applied (UART not working on flashed image)

[nicky_liu]

I am working with the Radio Test sample, but the project does not include any .overlay file by default. I created my own .overlay file and placed it inside the boards/ directory, but it seems the overlay is not being applied during the build. After flashing, the UART COM port outputs nothing, so I suspect the overlay was ignored.

2. Environment

• NCS version: (v3.1.0)

• Board: Custom nRF54L15 board

• Host: Windows 10 + VS Code

Hi,

 

Have you tried to enter debug mode to see if you are stuck in firmware somewhere?

Since you mention custom board, could it be that you do not have an external 32k source? You can setup the internal RC with this config:

CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y

 

Kind regards,

Håkon
