NAME
ftdi_eeprom - Tool for reading/erasing/flashing FTDI USB chip eeproms
SYNOPSIS
ftdi_eeprom [commands] config-file
DESCRIPTION
ftdi_eeprom is a small tool for reading/erasing/flashing FTDI USB chip
eeproms. It uses libftdi to access the chip, so you will need to have
the required permissions on the device.
The ftdi_sio module should not be loaded. You can prevent it to be
automatically loaded by adding it to /etc/modprobe.d/blacklist.
You have to unplug and replug your device to get the new values to be
read. Otherwise, you will still get the old values.
COMMANDS
--read-eeprom
Read eeprom and write to ‐filename‐ from config-file.
--erase-eeprom
Erase eeprom.
--flash-eeprom
Flash eeprom.
CONFIGURATION FILE
The configuration file contains a list of key-value pairs which will be
used to flash an FTDI USB chip eeprom. Comments start with #. The
beginning of such a file might look like the following:
vendor_id=0x0403 # Vendor ID
product_id=0x6001 # Product ID
max_power=0 # Max. power consumption: value * 2 mA. Use 0 if self_powered = true.
###########
# Strings #
###########
manufacturer="ACME Inc" # Manufacturer
product="USB Serial Converter" # Product
serial="08-15" # Serial
The example configuration file that could be found in
/usr/share/doc/ftdi-eeprom/examples is quite well commented so you
should be able to use it as a basis. The following keys are supported:
vendor_id
Set the vendor ID of the device. This value could be entered in
decimal or hexadecimal form, and should be in the range 0-65535
or 0x0000-0xffff, respectively.
product_id
Set the product ID of the device. This value could be entered in
decimal or hexadecimal form, and should be in the range 0-65535
or 0x0000-0xffff, respectively.
max_power
Set the maximum current the device will use, in 2 mA unit. Use 0
if self_powered = true.
manufacturer
Set the manufacturer string which normally holds the name of the
manufacturer.
product
Set the product string which normally holds the name of the
product.
serial Set the serial string which normally holds the serial number of
the product.
self_powered
Specify if the device is self-powered or not. The value should
be true or false.
remote_wakeup
Specify if the device supports remote wake-ups. The value should
be true or false.
use_serial
If this value is set to true, the serial string will be used.
Otherwise the default serial string will be used.
BM_type_chip
This value have to be set to true if you are using a BM chip.
in_is_isochronous
If set to true this option specify that the input endpoint is in
isochronous mode.
out_is_isochronous
If set to true this option specify that the output endpoint is
in isochronous mode.
suspend_pull_downs
If this value is set to true the pull downs are enabled during
suspend for lower power consumption.
change_usb_version
This value has to be set to true if you want to force the USB
version using the usb_version key. Otherwise the default USB
version will be used.
usb_version
Set the USB version of the device. The change_usb_version value
has to be set to true.
filename
Specify a filename if you want to dump the content of the eeprom
into it.
