20737 keep button(ing) causes system reset !!!!

[Anonymous]

we use Cypress 20737 SOC and based on hello-sensor for ur application
in some sensor query and calculation at timer thread (1sec-base).

However, we suddenly find that if user keeps pressing button without stop,

it will cause system reset. Is it that in timer thread, our app is too busy so that if keeping button-press,
SOC will spends more time on button behavior and delay the timer thread tasks.

so how can we handle this situation if it happens???

Perhaps let me re-phrase. You have a button interrupt configured to a GPIO. If you press and hold that button for long enough, you observed that occasionally the soc resets itself. Is this correct?

How fast are you pressing the button? Is there a while or a for loop in the interrupt handler?

My surmise is that the reset is because of a watchdog timeout. Can you try removing loops from your interrupt handler?
