Can I use JTAG to programme FLASH Memory?

Started by CC June 13, 2007
Hi,I'am planning to use AT91SAM9260 but i don't have a SAM-ICE which
is so expensive.So can i just use Wiggler JTAG to programme my
AM29LV160D(AMD Boot Sector Flash,16Mbit)?

If i can,how to implement it?

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 . -- \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ \/\/\/\/\ Chris Hills Staffs England /\/\/\/\/ /\/\/ chris@phaedsys.org www.phaedsys.org \/\/\ \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/

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. Jim
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 &#2013266048;29.- ;-)
See http://www.amontec.com/jtagkey-tiny.shtml

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

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. -- Best Regards, Ulf Samuelsson This is intended to be my personal opinion which may, or may not be shared by my employer Atmel Nordic AB

If 129 USD is expensive find another hobby. -- \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ \/\/\/\/\ Chris Hills Staffs England /\/\/\/\/ /\/\/ chris@phaedsys.org www.phaedsys.org \/\/\ \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/
