Strange problems in S32K144W in development (using PE and coding)

Hello expert,

There are strange problems i have met recently.

MCU: S32K144W

IDE version: S32DS V2.2

SDK version: 3.0.0

The project is modified based on the demo project MCSPTE1AK144_PMSM_FOC_2Sh for EVB which applys S32K144.

The problems are:

1. Clock configuration in PE will be recovered itself.

The two places below will always recover itself. While I want to disable them for the usage and S32K144W feature restriction.

2. I have developed the bootloader function. A little modification on app will lead to the failure of the running of app although there is no errors reported by S32DS. See pic below.

Here buffer is union type, buffer. fltdata.value is float type the same as temp_flt. I don't know why this little modification will cause the failure of software running.

And there may be some other strange modification like this causing the same problem. I think the root cause may be the same.

Can anyone help me on this? Thanks.

For problem 2, I have compared the srec files which are used in software update through bootloader, but there are many differences...
