JN5169 Error using interrupt function of timer 0

854648943 — Tue, 14 Jan 2020 09:00:47 GMT

Hi,

I want to use E_AHI_TIMER_0 to generate an interrupt。

But I ran into some problems, and I found that I only triggered an interrupt, but the program repeated my registered

interrupt function until the watchdog reset.

The SDK is SW-4170

Device is JN-AN-1217 Base device Router

Excuse me, where did I configure it incorrectly?

Here are some of my configurations

1.Initialize timer 0

2.Registration Interrupt function

3.Config irq_JN516x.s

4.log

Hi Tianheng, I hope you're doing well!

The issue could be related to an uncleared interrupt flag causing the interrupt to be constantly repeated, thus, causing a watchdog reset.

Could you please check to see if you added the following API to clear the interrupt flag?:

(void) u8AHI_TimerFired(E_AHI_TIMER_0);‍

Please let me know if you still have issues.

Best regards,

Sebastian
