This is on the GQ-4x4
This also seems to apply to the 64mbit one in SOIC16 format as well.
Using ADP-098 as instructed doesn't fix the problem, I had to create my own adapter to go directly to the 40 pin ZIF.

Even though you choose the SOIC16 format, the programmer uses the SOIC8 pin format.

SOIC16 is:
IO3 --- CLK
VCC --- IO0
RST --- NC
NC --- NC
NC --- NC
NC --- NC
CS --- GND
IO1 --- IO2



The adapter I needed to rig together takes the top and bottom two pins on each side of the 16 pin package and put them in the 8 pin configuration per the datasheet.
Otherwise, you get an unidentified (FFFFFFFF) chip and it doesn't function for read or write. Once wired as:
CS --- VCC
IO1 --- IO3
IO2 --- CLK
GND --- IO0

It functions normally. Although it doesn't seem to support dual or quad reading mode

Shouldn't the programmer be using the 16 pin format when you explicitly select SOIC16 from the device list?

Is there someway to update the pin configuration on the device list, or is that locked away in the program? The devices.txt doesn't seem to give any indication of pinout.

Yes, that is the same adapter, but there's no special or relocating traces on the pcb. The way it looks on top is the same way it looks on the bottom.
Testing the continuity from pin to pin shows it's 1:1 from socket to pin.

The pin configuration needed to use the 16 as an 8 was this:

75930 bytes

But my ADP-098 is just wired as a basically mechanical socket type change with no pin reassignments. in other words, it has a SOIC16 socket on top and 16 pins on the bottom for the ZIF, rather than 8 pins on the bottom with the assignments above.
I'll admit it's possible I might have knockoff adapters since the GQ was purchased from amazon as a bundle (but it was registered successfully and authenticates as genuine)

You mentioned a different class for the devices file, is it possible to make the adapter I have work for this without doing any jumpering of wires?




Does it look like this?

If you look at the data sheet of the IC, you will notice the SOIC-16 version of the chip only uses 8 of it's pins to program it.. Therefore what the company has done is made an adapter so that the 8 used pins of the SOIC-16 chip correspond to the pin out of it's WSON-8 counterpart, hence the requirement of ADP-98. If your chip is not being detected then there is a fault with your ADP-98.

The device 'Class' defines the pin-out the programmer uses.

Correct and the adapter can easily be tested with an ohmmeter or the hardware test function of the software.

Thank you! Excellent contribution to the community.
There is some DIP settings to change some pin configurations but I think the sufficient options needs to be set in the device class.
