I'm trying to write block data on the ICH6 SMBus controller by using the i2c-i801 module. But I always got error message "Error: no response (0x44)!". A scope shows that only the first four bytes of a data packet, i.e. Slave address, command code, byte count, 1st data byte will be sent. The other data bytes are not sent. I got the same error message when I tried to write two bytes data by using the I2C_SMBUS_WORD_DATA format. Any comments and advices are appreciated very much. Thanks.
