→Effacer l'EEPROM pour reprogrammer avec FT_PROG
To use the FT_PROG programming tool from FTDI you might need to erase the EEPROM of the FT232H to put it into a state where FT_PROG can detect the device. To do this you can use a small eeprom command line tool from libftdi by following the steps below. Note that these steps are for Windows users (since FT PROG is only usable on Windows).

First connect your FT232H board to the machine and follow the Zadig tool steps here to enable the libusb-based driver for the FT232H board.
First connect your FT232H board to the machine and [[RASP-FT232H-MPSSE-Windows|follow the Zadig tool steps here]] to enable the libusb-based driver for the FT232H board.
Once libusbK is enabled as the driver for the FT232H then download the libftdi Windows binaries from here (at the time of this writing you want the libftdi1-1.1_devkit_x86_x64_21Feb2014.zip archive). Unzip this archive and there should be a bin32 and bin64 subdirectory with a eeprom.exe and other command line tools. Open a command line terminal and navigate to the appropriate directory for your system (32 or 64-bit), then run the following command to erase the EEPROM on any connected FT232H board:

Unzip this archive and there should be a '''bin32''' and '''bin64''' subdirectory with a '''eeprom.exe''' and other command line tools. Open a command line terminal and navigate to the appropriate directory for your system (32 or 64-bit), then run the following command to erase the EEPROM on any connected FT232H board:
<syntaxhighlight lang="bash">
eeprom -e -p 0x6014 -v 0x0403
</syntaxhighlight>
Once erased the libusb driver needs to be uninstalled for the device to make it available for FT_PROG again. Follow the steps here to use device manager to uninstall and remove the driver for the FT232H board.
Once the libusb driver is uninstalled unplug the FT232H from the machine and plug it back in again. Run FT_PROG, slick the scan button (magnifying glass) and the FT232H should be detected.
