I want to open uart interrupt.I set the following register, or I can't access it（void UART1_IRQHandler(void))
please can you help set the register?
The IP register is not set correctly, the priority number must be written to the 7-4 bits of the register.
S32_NVIC->IP = 0x30; // Priority level 3
See Chapter 7.2.1 of the RM.
But this should not cause any problems.
Did you enable interrupts in LPUART CTRL register?
Is the name of the interrupt handler function correct?
As per S32K144.h, it is
Thanks.I named the wrong interrupt function name,but I only have to Sett Transmit Interrupt Enable to enter the interrupt.
Below is my register setting operation, I hope you can give directions.
