GINT RESET making system hang

Hi there,

While writing driver for GINT, as mentioned in UM, we need to reset GINT peripheral. When I do GINT reset, the system is getting hanged. The processor is LPC54608.

Please suggest solution to this.

Thanks.

I tested MCUXpresso SDK gint demo below gint reset doesn't cause system hang

RESET_PeripheralReset(s_gintResets[instance]);

Could you please test it as well? Can you use this demo code reproduce your issue?

Thanks,

Jun Zhang

Hi Jun Zhang,

Thanks for your reply.
Actually, I found the issue was due to continuous interrupt trigger. It was happening due to polarity mismatch.

Sorry for the inconvenience caused.

Regards,
Amar
