unable to run application in nRF52840 custom board using 48 pin package

[Shabinkumar]

Hi everyone,

I'm encountering difficulties running my application on a custom nRF52840 board with a 48-pin package using Zephyr NCS version 2.4.4 in VS Code.

The problem arises when the k_msleep function is called, causing the system to halt. The same code runs without issues on an nRF52840 DK. Both boards utilize a 32MHz crystal oscillator.

To troubleshoot, I've tried debugging the application but haven't found any clear culprits yet.

Here's a breakdown of my setup:

• Hardware: Custom nRF52840 board with 48-pin package, 32MHz crystal oscillator (no external crystal)
• Software: Zephyr NCS version 2.4.4, VS Code
• Application: Includes threads, timers, ADC, and BLE functionalities

I suspect that the absence of an external crystal on my custom board might be the root cause of the issue, but I'm not certain.

I would appreciate any insights or suggestions on how to proceed with troubleshooting

this is the Pinout of 72 pin package but in my board we have 48 pin package

Hi,

You can try to add these configs in your prj.conf file.

CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y
CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC_CALIBRATION=y
CONFIG_CLOCK_CONTROL_NRF_K32SRC_500PPM=y

Hello billtsai,

Adding these configurations solved the issue.

Thanks

THANK YOU! DAYS of debugging and nothing working, unable to find a hardware issue and this was the fix. It is beyond me as to why this isn't in their documentation.

Billtsai, you are a god amongst men. I hope the seas part when you wish to traverse between continents. I hope both sides of your pillow are perfectly cool at night. I hope whenever you walk into a room, everyone cheers. You, sir, have supernatural abilities. Cheers
