NRF52832 32.768k crystal不起震

[visionwang]

nrf52832工作一段时间后，出现了死机，测试各个电压都是正常的，但32.768K的晶体没有震荡信号；

请问在什么情况下，32.768K的晶体会没有震荡信号，如何解决；谢谢！

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,

Håkon

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.

After power off, then power up , nrf52832 can work properly。

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 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;

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?
