Hey,

I am trying to implement I2C featured external EEPROM with cc2640 for exchanging data between among them. But when I debug through code I came to know that I2C driver can not be get opened in I2C init function. How should i configure. I have set up my program by taking reference from sensor tag example.

any help?

Make sure your I2C SCL and SDA pins are connected well to EEPROM and have pull-up resistors on them.

Yes It's been properly connected. Hardware is perfectly working fine. I have also followed sensortag example but yet once i write data to EEProm and then when i try to read it back. I am getting empty buffer.

I suggest you to use I2C protocol analyzer to check if you send correct I2C command to EEPROM.

You can use scope instead but you have to decrypt I2C signal manually.
