I have a GQ-4x4 with the 7.11 software. One of the supported devices is the AT28C16 and the programmer can program it, but when attempting to erase the device, it pops up an error about not being able to erase this device.

How can I enable the erase?

Okay, so apparently nobody else has used a 28C16 with a GQ-4x4.

Is there a good definition of exactly what all the fields in the device descriptor file mean? Can I specifically program the erase algorithm, which voltages to apply to which pins, etc? The only documentation I found so far was lacking details. Maybe there is a more detailed explanation of how to add new devices somewhere? If I can find the documentation, I can probably solve my current problem.

Maybe you have an OTP.

Right in the devices.txt.

28C16 is EEPROM chip. It does not need to be erased before write. Fill the buffer with FF and then write will erase whole chip. Also, try slower speed when write fail.
