Hi，I am making a single firewire switch,  a button controls a relay，And requires low power。

This device is a Sleep End Device. Every 0.5S wake up onece.

Sometimes an exception occurs，Exception appears in this function：ZTIMER_vSleep();

Debug log：

********** AppApiSaveMacSettings()
********** ZTIMER_vSleep()Unclaimed Interrupt at priority 0

How to deal with "unclaimed interrupt with priority 0"？

How to locate the problematic code based on the exception log？（use .map file ?）

I haven't solved the problem yet.

I need help

Hi qingshu zhuang,

The ZTIMER_vSleep must be the last instruction before entering to sleep mode.

Please look at the JN-AN-1229 Sleep end device for a better reference.

PWRM_CALLBACK(PreSleep)
{
    vAHI_DioSetOutput(0,0x01);
    DBG_vPrintf(TRACE_APP, "APP: Going to sleep (CB)\n");
    vAppApiSaveMacSettings();
    ZTIMER_vSleep();
}‍‍‍‍‍‍‍

Regards,

Mario
