[...]although all read operations works fine.


How do you know that?
You don't check whether the memory ACKs ALL the written bytes, i.e. command, address...


I check control byte Ack, then address byte Ack, and ... then I get no Ack for data byte.


I can't see that in the version of code I downloaded... Did you modify it to do these checks?

Can't you go for the edge-by-edge version, simply stepping through the whole data transfer one-by-one, and see what happens directly on the lines (attaching 2 LEDs)?
