Hello,

Can you clarify what you need?

Are you trying to stop a user from connecting to the debug ports?

Best Regards,

Anshu

Hello,
I want to know if there are any security measures that give only restricted access to debug port like read protection/ wrote protection, debug port password, locking debug ports. I would need documentation for same.

Please use the following link to request access to AM65xx security resource download portal
https://www.ti.com/drr/opn/AM65X-RESTRICTED-SW

Once you have access to the portal, download "K3 Security Hardware Architecture TRM", and refer to "10.10.1 JTAG Security"
