nRF52840 Custom Board

[seongmincho]

Hello,

I am seeking guidance on the following issue:

Development Environment

• IDE: Visual Studio Code
• Toolchain Manager: v1.3.0
• SDK: ncs v2.6.0
• OS: Windows 11 Pro

Development Context

• Objective: Transmit sensor data via BLE to another BLE board.
• Development Board: nRF52840 DK
• Key Components:
  • SPIM: spi3
  • Timer: timer3
  • PPI
  • GPIOTE
  • Peripheral NUS (Nordic UART Service)

Problem

The code works successfully on the nRF52840 DK.
However, when transfered .hex file to a custom board based on the nRF52840, only partial functionality is observed.

Potential Files Requiring Modification

1. .dts 
2. .overlay 
3. prj.conf 

I would greatly appreciate any advice on where to start and what steps to take to resolve this issue.

Thank you!

Hi,

Have you created dts file for your custom board or do you need help in doing so? If so you can go through this video.

Thank you for your answer.

Yes, I agree that it’s necessary to create a new dts file for my custom board.

I’ll try that

Great!

Do pay attention whilst doing so if you don't have LSE and DCDC in your schematic/ circuit.
