I am implementing I2c Protocol using Aurix TriBoard with tc357 mounted on it based on the LLD example code. I was successfully able to communicate with the EEPROM mounted on the TriBoard using I2c. But, i have a problem when I try to communicate with an external slave. The external device always replies with the same value for any register read request I send. When I try to monitor the signals using oscilloscope I can see that the first write is sent where "an unexpected Ack occurs" and then it is re-transmitted again and then the response is received which is always the same response regardless of the register value i try to read. Does any one had a similar problem or might know what would cause such a problem ?
