Hi, I have the TIAO USB Multi-Protocol Adapter (TUMPA) v.1 with FT2232H chip.
The FT232h and FT2232H are different chip, the 232H is single channel while 2232h is double channel, probably it will work but I'm not sure...
Wiring on the first channel, on the JTAG connector of TIAO, has not worked, iteflash not see the EC, instead wiring on the second channel, on the SPI2 connector, iteflash has immediately found the EC and I'm able to read and write without errors. In your case, you have only one channel, so you dont have to experiment with different channels...

Hi, I have succesfully read and write my IT8227E-256 with this mod without errors.
In my case, it has worked with B interface only, so you must connect the wires correctly...

On my test, Thinkpad E14 Gen5 AMD, NM-F351, IT8227E-256, does not work...
Pin 7 does nothing
Pin 8-9-10 freezes
Have anyone tried the "XZZ ITE programmer"? Can it read/write the IT8227E?

Hi all !
