Hello,

I am trying to send data to FX2 - CY7C68013A from FPGA, but FIFOIN is not working.

When i try to program EEPROM by iic file, its failing. What can be the reason here?

Regards,

Avinash

Hello Avinash,

- You can use Tera Term to check if the data is being read. Tera Term does not recognize the ASCII equivalent of FF. So, use the logging feature of Tera Term to save and view the data.

- In case you are using the EEPROM to store the entire firmware file (.IIC file), the address lines of the EEPROM should be A2A1A0 = 001 and the EEPROM should be a double byte addressed EEPROM. In case you are using a small EEPROM to store only 8 bytes of data, the address lines should be A2A1A0 = 000 and the EEPROM should be a single byte addressed EEPROM. Use the appropriate vendor command from the Vend_Ax firmware to test the functionality of EEPROM.

Best regards,
