^^^^^
You somehow managed to write a the EEPROM content for at old FT232 style
device. How did you do it? Did you poke with ftdi->eeprom->xx direct?
Can you still erase it? Try also with mprog or ftprog.
The normal sequence is
- Open the device, now libftdi knows the type
- ftdi_eeprom_initdefaults(ftdi, ...) . libftdi should set the right
defaults depending on type
- Set all non standard values. If you compare DS_FT232R.pdf, 8. Internal
EEPROM Configuration with DS_UM232R.pdf 9 Internal EEPROM Configuration
you would need
ftdi_eeprom_initdefaults(ftdi, "FTDI", "UM232R USB <-> Serial",<serial>);
ftdi_set_eeprom_value(ftdi, MAX_POWER, 100);
ftdi_set_eeprom_value(ftdi, MAX_POWER, 100);
ftdi_set_eeprom_value(ftdi, CBUS_FUNCTION_2, CBUS_PWREN);
ftdi_set_eeprom_value(ftdi, CBUS_FUNCTION_3, CBUS_PWREN);
- ftdi_erase_eeprom(ftdi) to erase the EEPROM and determine it's size.
- ftdi_write_eeprom(ftdi);
Now you should be able to read the new values.
Good luck, and keep us informed.
