I have a GQ-3X and a ADP-042 and have been trying to read an SST39VF6402
(which is a 64 megabit device) but am getting the error "address exceed range" at 50%.

It does this with or without the adapter inserted, so anyone can try it as a test.

Ive tried it under windows 10 64 bit with signed drivers and under windows xp with unsigned drivers, both give the same error.

If I try and read an S29GL064N90TFI040 (with no adapter and chip inserted as I dont have this chip or the 8-bit adapter) which is also a 64 megabit device it works fine.

Are the address lines A19 A20 A21 connected correctly?

This message show up if you are trying to write the data to a location that exceeds the maximum address of the chip.

The problem may be caused by the device line in devices.txt

That device is there by default.
Please try it for yourself!
