Notice that (CS)TXE seems to have been killed off by Intel and merged into (CS)ME. Modern Atom based platforms now run CSME firmware (LKF - CSME 13.30, JSL - CSME 13.50, EHL - CSME 15.40 etc). The current (CS)TXE platforms (BYT, CHT, BSW, APL, BXT, GLK) remain as they are.

I successfully upgraded PiPO-X7s TXE 1.375MB M/D v1.1.1.1120 to TXE 1.375MB M/D v1.1.5.1162. Using FWUpdLcl -f 1.1.5.1162_1.375MB_MD_PRD_RGN.bin command.
I can’t figure out. Can I upgrade to TXE 1.2 1.375MB M/D v1.2.1.1161. For sure you can’t upgrade to TXE 2.0 1.375MB v2.0.5.3117!

Strange TXEI Driver v2.0.0.1094 (Windows 7, 8, 10) drivers don’t work on PiPO-X7s. I checked .inf file and hardware ID is only available in Windows 10 section. Missing for Windows 7 and 8.1 (NT 6.1).
I have found working drivers TXE_Win_64_1.1.5.1162 (Intel® Trusted Execution Engine Interface 2014.01.12 1.1.0.1064) on Intel® Trusted Execution Engine (Intel® TXE) Driver for DN2820FY, DE3815TY site.

Interesting how to upgrade TXE FITC?


I have adjusted Section A for TXE 1 on old Windows OS. Thanks for the feedback.


That doesn’t make sense. Please read Section C to understand what Flash Image Tool is.

As I understood Intel Flash Image Tool (FITC, FITc or FITC.exe) is tool which was used to flash BIOS initially? But I updated TXE with FWUpdLcl (Intel Firmware Update Utility Version: 1.1.5.1162). Why info wasn’t updated?

What is difference between TXE 1.375MB M/D and TXE 1.375MB I/T?

FIT is a tool, the tool used to build/configure the firmware. It is not something you update, ignore it. TXE 1.2 is technically compatible with 1.1 but it’s a different branch which existed for some reason on a very small number of devices. M/D and I/T are different SKUs. You are up to date, nothing more to do.

Tried to upgrade to TXE 1.2 1.375MB M/D v1.2.1.1161 with FWUpdLcl -f 1.2.1.1161_1.375MB_MD_PRD_EXTR.bin without success.

Is it possible to upgrade with Intel Flash Programming Tool (fptw.exe). Only I don’t want to corrupt TXE DATA Region (configuration stuff). Do I gain any benefit? Generally all TXE stuff is one security concern :).

As I said, you are up to date TXE wise, nothing more to do.
