S32K312 HSE CLK & UTEST write error

[David2024]

MCU:S32k312; MCAL:MCAL4.0; FXOSC:24MHz.

when config HSE clock to 120MHz and write data to UTEST(0x1B00 0000), then there will be a Hardfault.

when config HSE clock to 60MHz, we can write the data to UTEST successful.

We didn't have this problem when we used MCAL1.0 before.

Hi

What is version of RTD?
Have you referred to the methods described in chapter 9.3. Improve performance of Secure Boot Application note v0.1.1.0?

IMPORTANT: The 120MHz cannot be set by software directly. It won’t work. Please check the following post. It has information related to this problem: HSE provides RSP_NOT_SUPPORTED response 

Best Regards,
Robin
