******************************************************************************* The purpose of this demo application is to present a usage of the UART IP Driver for the S32K3xx MCU. The example uses LPUART0 for transmit 20 packets with each packet of 21 bytes using the Interrupt in cyclic order. Also when receiving UART packet generate Idle interrupt when variable length of data is received. I used coolterm tool to send the string of data. If Data send by cool term is less than 20 bytes which is set by API call Lpuart_Uart_Ip_AsyncReceive(), then Ideal interrupt is received RTD driver modified in RTD --> Lpuart_Uart_Ip.c.

This will display the callstack at the time hardfault occur, and LR address contain the address where the HARDFAULT occur. Enter address in Disassembly window And press enter, this will take you to code location where the hardfault occur. Then you can review your code setting or code usage why this hardfault is coming.
