HSE installation issues

[杨工1131]

Help! I have written a routine for HSE firmware installation by referring to the official demo project. However, no data is present at the HSE installation address 0x007E0000 after I perform two resets. Does this mean the HSE installation has failed?

This is the ld file

This is the rewritten IVT vector

Finally, I attach my HSE installation demo project.

The S32 version is 3.6.8, the chip is S32K314, and the RTD version is 7.0.1

At first you should see HSE_CONFIG_GPR3 register (0x4039C028) to find out whether your HSE FW is installed or not.
