Programming flash connected to CPLD via JTAG

Hello!

I want to revitalise a question at was asked in 2001, because I hope
something changed during the time.

How can a AT49LV001 flash by programmed through a XC9536XL CPLD and
its JTAG-connector with really low cost?

All address, data and control pins are connected to the CPLD, so ISP
via JTAG should be possible.I'm sure there are lots of tools available
at this time for programming, but still I don't want to pay >10k USD.

Does anyone know if it's possible to program at flash with JAMPLAYER
sw from altera? How much effort would it be to implement flash
algorithms?

regards,

Wolfgang

how much would you be ready to pay?

there is/was some example JAM application from some russian site, not sure
if the site is online any more. it contained some flash functions. I have
not tested them though.

writing an JAM app is one choice, doing it from scratch isnt very
complicated either.

I have an Win32 application that programs an AMD flash that is connected to
2 different PLDs and part of the pins to Altera PLD that is not in jtag
chain, so in order to program the flash I load the altera fpga (simple 1
wire from pld to flash bridge) then use JTAG scan to program the flash.

the application is in Delphi6, source code could relativly easy to adopted
for board.

What would you consider low cost for a product like this?

It's not very difficult to do if you have some programming experience.
You have to know the position of the pld in the jtag chain, you have
to parse the bsdl file for the cpld, you need to know which pins are
connected to the flash (possibly parse the edif netlist for the board
or make a separate description) and then generate patterns which will
control the pins connected to the flash to generate write commands
with the data you want to write.

Thanks for your input. It seems that the trial version of
universalscan supports flashprogramming and hopefully my AM29F010 too!
That would be the easyest solution, the price seens to be fair if it
keeps the promises.

and you are ready to go!

We're using Intellitech which was recommended by broadcom datasheet for
FLASH programming with their chip.  It was only US$875.00 and has
models for most FLASH devices.  I looked and the AM29F010 is in the
Intellitech library.
http://www.intellitech.com/products/eclipseboundaryscanflash.asp.   I
ordered it online.
