GQ-4X - Am29F080 1M Flash

General Description

The Am29F080 is an 8 MBit, 5.0 volt-only memory organised as 1,048,576 bytes. The 8 bits of data appear on DQ0-DQ7.The Am29F080 is offered in 40 pin TSOP and 44-pin SO packages. This device designed to be programmed in-system with the standard 5.0 volt Vcc supply. A 12.0 volt Vpp is not required to program or erase operations. This device can also be programmed in standard EPROM programmers.

Adding or Updating the "devices.txt" file

The devices.txt file is a database file that contains all the information on how different devices are programmed. We need to add this flash chip as a new device as it does not use the same pin-outs as the TSOP40 header. It is prudent to make a copy of the original file before adding anything.

This needs to be updated initially for both this chip and EPROM cards.

To update this file go to the installation files, in Win8.1 the default was 

C:\Program Files (x86)\GQ USB Programmer

Right-click on NOTEPAD.exe and  Run as administrator (otherwise you will not be able to save it).

Insert the following line Marked in orange in the FLASH - 8bit mode section.
