Can I just change the VID and PID of FX3 with the help of small EEPROM

Yes. You can do that.

You can change just the VID and PID value of FX3 with the help of a small EEPROM connected to FX3. It should contain the following values in the starting 8 bytes:

1.: 'C'

2.: 'Y'

3.: 0xAB  (EEPROM Ctrl based on the EEPROM that you are using)

4.: 0xB2  (Boot Mode)

5.: 0xAB   (PID LSB - based on your PID)

6.: 0xCD  (PID MSB- based on your PID)

7.: 0xAB  (VID LSB- based on your VID)

8.: 0xCD   (VID MSB- based on your VID)

This will be helpful if you want to load .img file into FX3's RAM after connecting it to host PC.

Thanks,

sai krishna.
