What do you see on scope? It is trying to write to the 24c02?
You have to use pull-up. Internal pull-ups are disable in this example.
You can enable them in PORTA[PCR] registers.
Can you be more specific? What exactly you need to know?
If you need to use pins 6/7 instead of pins 0/1 which are selected in this example by default, you must change routing of the pins in the pin_mux driver as well.
