@JColvin I am attempting to flash the EEPROM attached to the FT2232 device on a board with a Zynq7000 series chip. I have already configured the EEPROM with what I believe are the write settings (Port A to D2XX direct). I am trying to use Vivado's program_ftdi to read in if there is any connected device. The program_ftdi feature is finding the device so I believe something is wrong with the EEPROM attached to the FT2232 device and I would like to set that to the proper settings so that Vivado can detect the target chip
