Hi , all
How to set S32K3_Host debug permanently disabled?
In HSE_B RM, it is possible to disable JTAG.
In S32K3 RM - UTEST, i can't find any more information.

Unfortunately, It cannot be disabled, only ADKP (Application Debug Key/Password) protected.

Hi Xianlong,
If you have any question about the HSE_B FW, please create a ticket as the documentation is under NDA.
The information below is taken from the S32K3 RM.
Without the HSE FW, the MCU can be password protected:
This can be done at CUST_DEL Life Cycle stage only.
Once the Life Cycle is advanced, the MCU is password protected.
With HSE FW:
Please refer to HSE DEMO APP.

Daniel
hello, i also have a same question about this.
as you said, if I set/advance the LC status to OEM_PROD or IN_FIELD without provision ADK/P and also didn't enable HSE.
what will be happen? Dose it means that the JTAG debug shall be permanently disabled?
As I understand it, NXP deleted the relevant bit description in the DCM register, DCMDEB register- HSE_APP_DIS_FLD, HSE_DBG_EN_FLD, HSE_APP_DIS_OEM and HSE_DBG_EN_OEM bitfields are removed.
Disable debug can only be implemented using HSE-H, that is, paid version HSE.(in HSE_B I saw the API,but can not use)
Otherwise, only password protection can be used for authentication.
