Hi,
I'm trying to read/write on a EEPROM AT24C256 using I2C function, and it doesn't works. Using pins as GPIO it works. I've tried with I2C0,I2C1,I2C2 interfaces. The bytes are sent but there isn't acknoledge from EEPROM, with ARM working as slave. The test board i'm using is MCB2300 Vers.3
Could any one help me?
Thanks! Regards!
"The bytes are sent but there isn't acknoledge from EEPROM, with ARM working as slave"
The ARM must be master !
Also start with setting the I2C frequency at lower speed like 50Khz. Once you get the results then increase it

...sorry about what i wrote...ARM is working as MASTER...
I have a similar device (24LC1025 from Microchip) working with MCB2140 board using I2C0 interface.
