For all who are interested in flash memory problems...

Some devices can optionally used in 8 or 16 bit data mode. In my case I use the 8 bit mode. If you can read out your cfi table, you can be sure that your flash device is correct implemented.

But be carefully, on top of this information, you can find a sentence, in my case "found cfi table in 16 bit mode".

This tells the programmer in which mode do you use your flash ram. but in my case was this a wrong information.

You should write your flash in command line mode with the parameter --width=8 ;)

By the way, my flash device is called AT48BV163D
