I have 2 questions
1.) in final design fx3 will work as slave fifo and it will be booted from an eeprom through i2c. Does that mean that we need to check the box near the i2c in gpif2 designer?
2.) By choosing i2c in gpif2 does that mean that we are implementing i2c communication to fx3 or only boot option.
1. The I2C, UART etc etc checkbox is to make sure that there is no conflict in pin usage between GPIF II and I2C, UART etc.
2. By clicking I2C you're not enabling or disabling anything, you're just letting the tool check for incompatibilities in pin usage. That is all.
