Texas Instruments has updated their public OMAP4460 Technical Reference Manual (TRM) to version I. Also, the
OMAP4430 TRM is now at version R.

Since these documents are really difficult to find on TI’s website, I have created these download links to these
publicly available OMAP technical reference manuals.

• “OMAP4460 Technical Reference Manual (TRM), Silicon Revision 1.x, Version I”,
  available here (22 MB download).
• “OMAP4430 Technical Reference Manual (TRM), Silicon Revision 2.x, Version X”,
  available here (23 MB download)

You can learn more about how TI uses Arteris interconnect IP in
OMAP from our website.

Arteris’ network-on-chip interconnect IP fabric is used as the main L3 interconnect within TI’s OMAP 4 platforms.
The L3 interconnect is the main “backbone” interconnect of the entire OMAP processor system on chip (SoC).

The OMAP4470 TRM is not available publicly yet, as far as I can tell. I will post a link as soon as it is
released. Also, there are no OMAP 5 TRMs that are publicly released yet.
