first step: Build the latest libftdi 1.3rc1 from source
or use at least libftdi 1.2.
For a raw copy of the eeprom content,
create a "ftdi_eeprom.conf" config file like this:
##################################################
filename="eeprom.copy" # Filename to save eemrpon config
eeprom_type=3 # number three is for type R chips
flash_raw=true # raw copy of unmodified image
##################################################
- find your USB device id using "lsusb" command.
Adjust the cmdline below if it's not the default 0x0403:0x6001
- Read out current eeprom. Will save to "eeprom.copy" file
./ftdi_eeprom --device i:0x0403:0x6001 --read-eeprom ftdi_eeprom.conf
This should give you a "eeprom.copy" file with 128 bytes
for type R chips.
- Unplug chip and plug in other chip. Flash the device
./ftdi_eeprom --device i:0x0403:0x6001 --flash-eeprom ftdi_eeprom.conf
You might have to adapt the USB vendor/device id
and the path to ftdi_eeprom according to your specific siuation.
Best regards,
Thomas
