Without knowing more about what occurs, I cannot say what is causing this. Are you able to print the assertion information, or recreate the issue under debug mode?

After power up again, device hasn't crashed up to now; so I can't provide the debug information on where it fails; What factors will cause the crystal stop working?

Thanks;

Hi,

You mention that the device crashes. Are you able to provide debug information on where it fails?

Here's a blog on how to read the error in nRF5 SDK: https://devzone.nordicsemi.com/b/blog/posts/an-introduction-to-error-handling-in-nrf5-projects

Kind regards,

After working a period of time, nrf52832 crashed; First , I checked the power(3.3v), it is ok, then checked the clock(32.768k), but it didn't work. what will make crystal(32.768k) not work? How to fix it?

I viewed the log, i found the fourth pin jump(0 to1 ,1 to 0) constantly, this is abnormal phenomena; Is it ralated to clock's crash.

Thanks.

Hi,

We appreciate if you input cases in english.

Have you debugged your issue? Is your firmware asserting or faulting in any way?

Kind regards,
