Device. It is not a supported device so I am trying to create a device for it. I have had some luck using a 16 bit adapter. My problem is both the data screen and programming is not 16 bit behaved. The data looks like normal 8 bit bytes. The problem is programming is writing the same byte vale from even byte to both even and odd bytes. This device is similar to an intel i28f400 device except the micron wants to put the high byte on the upper data lines and the low byte on the low data lines. The intel device uses internal registers to buffer the data as a word vs the micron single 16 bit cycle. The 16 bit tsop 48 adapter gives me close to the correct device code, erases and performs an incorrect byte/word programmed memory. If I use an 8 bit adapter, I cannot find a device that comes even close to getting the correct device ID. I suspect I need a class code different from what I am using. Is there a document about class codes? I am guessing that is what controls the programming algorithm and software behavior. This is the whole reason I bought the programmer but didn't realize the same but different nature of the supported devices vs this one Thanks in advance[?] [/quote]    Insert an Image File Check here to include your profile signature.
