Tool/software:

Where can I find a list of publicly available registers for J722S?

We have them for the J721s2, but looking for the registers for this one.

Additionally, we are wanting to disable JTAG with a register setting, could someone confirm this is possible?

Hello Evan,

The TRM is the reference for registers:

document-pdfAcrobat J7200 DRA821 Processor Silicon Revision 1.0 Technical Reference Manual (Rev. C)

I'll reassign the post to answer your JTAG question.

Regards,

Kyle

I think you want this link for the TRM and registers for J722S (AKA J7AEN) https://www.ti.com/lit/zip/sprujb3 it looks like Kyle pointed at J7200.

The J722S SOC will have types HS (FS & SE): High security and GP general purpose. The commonly orderable part will be an HS-FS device and you have the option to burn in your own key to make it an HS-SE. JTAG on HS devices is enabled or disabled via certificates which are part of your boot image. As such you will have a strong control mechanism to open up or lock down jtag which is part of the standard offering.

Regards,

Richard W.
