Willem on Am29f400BB bosch 7.5

[invasione]

hi all ..

I have a willem when I try to write the file ori on the memory is written, checked and read normally, however, when then the balance on the ecu and I read on the tour I can read it only in boot mode and basically, when the identify is missing a number on the end.. reading the file ? completely different from the ecu that I have written ..

where am I wrong?

to make you understand of 3 photos ..

I have to select the chip that I have under am29f400 or 29f400? because selecting only 29f400 if I do ID from the willem nn I recognize the chip while with am29f400 recognizes it correctly then skip write 0xFF must be enabled?
