just ordered ylur jtag and not sure if it supports my router flash chip

rtoledo2002

Hy Tornado I just orderd the bundle universla jtag and I need to write the REDBOOT load strap into a Actiontec mi424wr Router used by Veriozn for their FIOS customers.
the unit has a js28f640 Intel Startaflash ship it's a 8192Kx8 th unit has 128k of flash too on a couple of Hynyx hy57v281620etp-h.
Verizon has disabled TELNET in these units so you can't change the Jungo boot and replace it with redboot
please let me know what software I need to do this too.
спасибо (spasibo) ???

I think I found the answer here
http://www.tiaowiki.com/w/TJTAG
looks like the Intel IXP 425 and the flash chip is listed in teh covered list on the link I put here so good news
hope I g\figure out how to write the redboot to it!

no matter what tjtag does NOT recognise the chip. I have tried both buffered and unbuffured pins looking at the pins used on the db25 on your tutorial for the linksys I selected the appropiate pins on the 20 pin jtag for the Actiontec mi424wr
I put db #2 to jtag pin TDI #5
db#3 to jtag pin TCK #9
db#4 to jtag pin TMS #7
db#5 to jtag pin TRST_N #3
db#13 to jtag pin TDO #13
HELP

Please try zJTAG: http://zjtag.sourceforge.net/
It supports INTEL XScale IXP42X series.
