Device reset in specific device.

[Chongchun Moon]

Hello,

  I am using NRF52832(WLCSP package) and nRF5_SDK_15.2.0 for the product.

  I also use IAR Embedded workbench 8.32.1 as IDE.

  Few hundreds devices are assembled in factory line.

  In that event, I met one device which has weird situation.

  It is supposed that device is hang in somewhere, It makes system reset.

  If I add unused code, that situation is gone. or If I change optimization option, that situation is gone also.

  It looks like it may related alignment. But I don't know.

  Do you have any idea why this situation is occurred? 

  And, Please tell me how to approach to resolve this situation.

  If you need more information, let me know please.

Thanks,

   Chongchun Moon

Hi

Could it be that either the LF or HF crystal on your board is faulty/not connected properly? Also, please specify what changes you've done when "changing code optimization".

You should also check to see if this works in "debug level none" mode.

Regarding on-site support, you'll have to contact your RSM (Regional Sales Manager) for details. If you need their contact info, please use the Sales related questions form (make the subject on-site support).

Best regards,

Simon
