SPI initialization hard faults

[Pod_GaetanoG]

Hi, I am trying to configure my RTD of s32k344 microcontroller and I have a problem with SPI Init process. When I choose LPSPI from 0 to 2, they work well, but from 3 to 5 it goes in hard fault. I also tried to change project, workspace and even board, but it always happens in the same manner.

In attachments you can find the screenshot of the problem above.

Thank you in advance.

Hello @Pod_GaetanoG,

Since the CM7 core has very similar fault handling as the CM4, you can refer to this document/example:

https://community.nxp.com/t5/S32K-Knowledge-Base/Fault-handling-on-S32K14x/ta-p/1114447

and identify the type of the fault, find the PC address of the fault, or the bus address in case of a bus fault exception.

Thank you,

BR, Daniel

Hello,

Have you check if the clock for the LPUART you want to use are enabled ?

MCUModeSettingConf => MCUPeripheral => clock enable
