How to Modify your EZ-Kit to Use Flash Memory
this page is for the am29f010. If you're using an am29f040, then you should
go here instead.
Hi! In order to use Flash memory, the DSP on your
EZ-Kit Lite has to be able to send the WR/ (
spoken: write-bar) signal
to the flash memory chip socket. The EZ-Kit was
only really designed to work with EPROM/PROM, so you'll
have to make this connection yourself, or have a friend
help if you've never touched a soldering iron before.
So, follow the pictures, and good luck!
Okay, turn your ez-kit over, and hold it like so. Make sure
the serial, audio and power connectors are ALL UNPLUGGED!

What you're going to do
You're going to solder one wire on, and you're going to
cut one trace on the board! The wire you're going to
solder on is the BLUE ONE in the BOTTOM RIGHT of the
picture. IGNORE the red ones and the blue one at the
top of the picture; they're for other weird functions I
can't get into right now.

Cut the Trace First
take a close look at the EPROM socket pins in this next photo...
See pin #1? It has a SQUARE hole, instead of a CIRCULAR
one. Nearby (direction: down), you'll see a scratched-up bit.
This is the trace you must cut. Use an exacto knife, and simply
You will go through several layers. First, you will
scrape the thin green lacquer off. Then, the trace will appear
very shiny. Scrape that shiny, gold-colored trace away. When you
are done, you should really get a multimeter, and VERIFY that there
is no connectivity from one side of the trace to the other! This
is important, because there is so much fiberglass and stuff in the
way, you can't tell just by looking at the board.
Connect a wire
The wire runs from P2 pin 39 (the header on the
ezkit) to the EPROM socket, pin #31.
You can either count from pin 1 up to 39 on the
ez-kit board, or use this picture to help you find P2 pin 39.
It' the 6th one down, on the left.
Again, it's the WIRE on the RIGHT in this picture,
NOT the one at the top.
Use this picture to help you find pin 31 on the
(dig that crazy reflection off of my camera's lens- the
You are now "cool."
