Hi, I updated my ZBOX CI323 nano (Intel Celeron N3150) BIOS to the latest version 2K160913 and it went fine, but a day or so later I noticed the CPU is slower than usual. It's not using the turbo clock anymore.
Looking for errors I noticed in device manager the Intel Trusted Execution Engine has a yellow exclamation mark

(device could not be started (Code 10))

and in event log there is an error for TXEIx64

(Intel(R) Trusted Execution Engine Interface driver has failed to perform handshake with the Firmware (FWSTS0: 0x01040190, FWSTS1: 0x100A0000).)

Also the TXE Information section inside the BIOS settings shows "N/A" for both Sec RC Version and TXE FW Version, this was definitely not the case right after updating the BIOS.
I already tried re-flashing the BIOS again, it shows no errors but doesn't help.
The change-log specifically mentions changes to the update procedures for ME / TXT updating, I'm wondering if this BIOS is just bad or the TXE unit dying on its own is a thing (would be quite the coincidence).
Is TXE even related to the turbo clock not working anymore?
I'm on Windows 10 Pro.

I already tried TXEInfo/TXEManuf but they error out, even the efi-versions.
[Guide] Clean the Engine Initialized DATA section of a SPI dump would this help me? I'm not sure which section to follow for Braswell.


/e:
I noticed they use fpt in their flash script

set AfuName  AfuEfix64.efi
set BIOSName B301P018.bin
set FptName  fpt64.efi
 
set BlkNum 0
if exist fs%BlkNum%:\%AfuName% then
fs%BlkNum%:\%AfuName%  fs%BlkNum%:\%BIOSName% /p /b /n /x /r
fs%BlkNum%:\%FptName%  -f fs%BlkNum%:\%BIOSName% -txe
fs%BlkNum%:\%FptName% -greset
goto success
endif
 

When I run the fpt64 -f B301P018.bin -txe part on its own it says Platform: Cherry Trail.. that can't be right, can it?

First try "fptw -greset" command and check if the problem is solved after the reset. Otherwise, follow the cleanup guide (Pre-Skylake) and reflash the SPI image with a cleaned+configured TXE. Your problem seems to be TXE related. I suspect Zotac used a previously initialized dump at that BIOS. Both BSW and CHT use TXE 2 firmware.

You did do something. Removing the power from the system for more that one minute is equal to a -greset so that's how the TXE got fixed.
