topic I have a question about using utest. in S32K

I have a question about using utest.

Hello.

I'm currently using the s32k324 board.

I'm doing utest to put a value in 0x1B000000 for hse activation.

As shown in the current picture, the last part of the 0x1B000000 value contains an odd value.

If so, I would appreciate it if you could let me know if you can activate hse in this state, or if not, what should I do.

I'd really appreciate it if you let me know quickly because I'm in a hurry

This field has 8 bytes of length. What you are showing is out of range.

Thank you for your answer.

Then, if I change the value of the 8 bits in front of you, will hse be activated?

If is only one step. Also you will have to install HSE firmware.

Procedure you may find for instance in AN744810 or HSE-B Firmware Reference Manual (both are secure files).
