Can I use JTAG to programme FLASH Memory?

No it's not!

Use a USB JTAG not a parallel one

They tend to have SW available for this.

If you have to ask how to write your it's not worth it. Buy the ICE unless your time is worth Zero per hour .

I assume this device is connected to the microprocessor's address/data lines? If so, use the micro's JTAG to manipulate the address/data/CS lines appropriately to program the device. That's a popular flash chip (don't know about the micro though)--your wiggler might even have support for this so you don't have to write anything. Otherwise, you'll have to write a program to load (clock) the appropriate outputs into the micro.

The Amontec JTAGkey series are generic USB to JTAG solutions.

Try Amontec JTAGkey-Tiny + OpenOCD JTAG server. The ARM926 are supported by this couple -> only ?29.- ;-) See

But if you want

- to be able to debug/flash any ARM7 ARM9 XSCALE

- to download any Atmel AVR

- to download any FPGA / CPLD (Altera Cypress Lattice Xilinx...)

- to customize your own JTAG Boundary-Scan software

- to have an auto-sense JTAG Port from 1.4V to 5.5V ... you should select the Amontec JTAGkey see

SAM-ICE = $129!!!

You would be better off to use an AT45DB161D since you can program that using the UART or USB device using the SAMBA suite (Free of Charge) from Atmel and a serial/USB cable.

If 129 USD is expensive find another hobby.
