JTAG Disable

Hi,

I wanted to disable JTAG permanently. If I advance LC to OEM_PROD, will it be disabled?
Should I need to provision ADKP for this? I don't want to recover it.

Hi @petervlna ,

I am able to disable JTAG successfully by using the password, Now I want to disable it by dynamic challange. For this I have provisioned a key AES key to secure nvm and giving the handle of this key as pAttr value but I am getting HSE_IP_SRV_RSP_NO_RESPONSE from HSE. Please refer below snap of my code,
