S32K3 HSE

I am currently using the S32K344 chip to debug the information security function. I am flashing the Boot software through PE and hope to integrate the HSE installation part of the code into the Boot project. Is there a sample file for reference? The attachment shows the modified part of the code in the current application project. Currently, the software has entered a hardware error when running

I would guess, we don't have specific example project combining HSE FW installation with further application simultaneously.

There are examples S32K344_HSE_FW_INSTALL in HSE examples package
https://www.nxp.com/webapp/Download?colCode=S32K3_HSE_DemoExamples

which can be used as a base.

The above code is written based on this sample file. Before determining whether to perform UTEST region writing, the address value of 0x1B000000 needs to be obtained. In my application project, directly obtaining 0x1B000000 through a pointer will trigger the hardware error void HardFault_Handler(void). However, when flashing S32K344_HSE_FW_INSTALL, 0x1B000000 can still be directly obtained through a pointer without any problem. Could you please tell me what causes this and what solutions are there
