PTN3460 Support

Hi Team,

Datasheet of PTN3460I mentions a "I2C-bus utility and programming guide for firmware and EDID update" document. I am not able to find the document related to I2C bus utility and EDID update tool. 

Further, Can we flash the internal flash of PTN3460I using DP Aux. If so, is there a utility for the same.? PTN3460 (Flash-over-AUX) utility is only for firmware update or for EDID update also?

Re: PTN3460 Support

Hi,

The document referenced in the PTN3460I datasheet as "I2C-bus utility and programming guide for firmware and EDID update" corresponds to AN11606 – PTN3460I Programming Guide (for the PTN3460I) and AN11128 – PTN3460 Programming Guide (for the commercial PTN3460). Both are publicly available on NXP.com:

AN11606 – PTN3460I Programming Guide (Rev. 1.4) — covers I²C-bus configuration table structure, EDID programming (up to 7 EDID data structures), all register definitions, and step-by-step procedures for writing EDID and configuration data into the PTN3460I internal flash via I²C.
AN11128 – PTN3460 Programming Guide (Rev. 1.8) — the equivalent document for the commercial PTN3460BS variant.

Regarding your questions about the DP AUX interface and the Flash-over-AUX (FoA) utility:

Flashing the internal flash via DP AUX: Yes, PTN3460I supports programming its internal flash through the DP AUX channel. The registers can be accessed either via the I²C-bus interface or via DP AUX.

Flash-over-AUX (FoA) utility scope: There are two separate FoA tools for PTN3460/PTN3460I:

FoA firmware updater (a separate tool for PTN3460IBS firmware F2) — used exclusively for firmware version upgrades via the DP AUX channel.
FoA EDID Updater — a separate utility used specifically for EDID updates via the DP AUX channel.
