JTAG Secure Access

[juanmanuelmonte]

In an industrial application for critical infrastructures, we have developed an embedded CPU engineered by P1021.

A new customer is requesting that our JTAG protects the processor of any kind of download, or any other kind of access on this port.

I am wondering, if it is possible to permanently disable the JTAG access port, or to have a means to have Secure Jtag access (by private keys or whatever).

Do you have any information about this?

Thanks in advance for your support.

Sorry, the processor does not allow to disable JTAG port or make it secure.

Regards,
