Re: [U-Boot] soft i2c behaviour on address not <ACK>ed

Hello Dirk,

While debugging an I2C problem I found in soft_i2c_read() and soft_i2c_write():

if(write_byte(addr>> shift)) { PRINTD("i2c_read, address not<ACK>ed\n"); return(1); }

and

if(write_byte(addr>> shift)) { PRINTD("i2c_write, address not<ACK>ed\n"); return(1); }

This means that these functions are left without sending a STOP condition to the bus and with SCL held low. Is that really intended?

This seems a bug to me ... could you send a patch?
