Ok so on build 282 with firmware 1.09 it reas and writes 100% = Correct
With build 282 with firmware 2.02 it does not detect the flash ? Not Tested
with build 321 with firmware 2.02 it does not detect the flash ? Correct


With build 321 with firmware 3.01 it detects the flash but does not write ?

read ok.

and

write only 00 (zeros)

Ok i will let the developer know and see if he can rectify it .

Did you try it with the 5v setting and dip switches to the ON position yet ?

The developer tested this chip using 5v , now there is a possability he had it as a stand alone chip , If you cannot remove the chip i would not recommend using the 5v then.

I will speak to the developer regarding this and post back once i have an answer.

Did you try with the FCUSB on the 5v setting and both dip switches to the Enable (ON) position ?

I've tried 5v setting jumper enabled and both DIP switches ON, but still No luck.

Try Built 304 w/ firmare 1.09 still no luck

Did you try with just Build304 or have you tried the latest build and firmware as well ?

you have to set up vcc to W pin (9) so you can enable write on chip , without it you would only be able to read from it .
