S32DS v3.5 + S32SDK RTM 4.0.1
examples: S32K144/driver_examples/communication/uart_pal_echo
In this example, we modified the TX of LPUART in pin_mux.c to PTC9 and RX to PTC8.
Added PCC_SetClockMode between CLOCK_SYS_UpdateConfiguration and PINS_DRV_Init in main.c, otherwise the program would enter DefaultISR at line 139 in pins_port_hw_access.c.
But after circumventing this issue, when initializing the LPUART_DRV_Init, the problem as shown in the picture occurs.
Instead of using an EVB board, we use a development board of our own design.
What is the reason for this issue? How to modify it?
I just followed your test process.
1.modified pin mux
2.debug process is ok on myside.
So don't doubt whether there is a problem with this demo, you may need to check your hardware, such as external crystal oscillator，because the lpuart module clock source is external crystal oscillator in this demo.
