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.

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.

Regards,

Daniel

Hi,@danielmartynek

Thank you for your help, I have read the information of Debug projected by password. And i wonder can JTAG be  permanently disabled? where can i get more information.

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