- The EEPROM that you have mentioned (AT24C256C) is only of the size 32kB. Please ensure that your firmware size is lesser than this. Most of the FX3 SDK examples are larger than this size.
- Also, to use an ATMEL EEPROM of 128kB size, the A2, A1 pins must be tied to GND and the A0 pin must be left unconnected. Please refer to the below document for more details.
I made a mistake.
I think I used 256Kb incorrectly as 256KB. Again, the memory size is not enough.
