S32K SDK LPUART Stuck Servicing IRQ Handler

[john_floros]

Team,

I have a customer that is using LPUART in the SDK.  They get into a situation maybe after two minutes after running where the S32K stops transmitting because the LPUART_DRV_IRQHandler keeps running continually.  It continually enters the handler sees that there is no transfer happening and exits and then repeats.

Thoughts?

Hi, 

it is possible share customer's project - you can send it internally to my email address. I'll look at it. Thanks.
