RE: FT245 unique chip ID

["Marko Cebokli" <marko.cebokli@xxxxxxx>]

I can read that, but I can also change it using the »ftdi-eeprom« program.

However, the ft245 datasheet mentions a factory programmed, non-alterable chip ID, which can be used to identify each particular device.

This is described in the AN232R-02 application note from FTDI.

 

I can see some »random« values in the last eight bytes of eeprom, cuold that be it?   I've run   »eeprom –w«   and these last bytes did not change.

You can read the chips' serialnumber, which is 8 characters in base36

 

ftdi_usb_get_strings(ftdi, dev,
                                     vendor, sizeof(vendor),
                                     name, sizeof(name),
                                     serial, sizeof(serial));

Hello,

Is there a way to read this using libftdi?
Using the "ëeprom"   example program, I can see some random looking bytes at
the end of eeprom, is this it?
I guess it is not the "serial number", because that can be changed?
