JTAG error

[gordonc]

well number one don't go from the top use the bottom and make sure your j-tag is facing the right way if it's backwards it won't work hope this helps

[gordonc]

what program r u using and is your j-tag a bufferd j-tag

[gordonc]

well I am not sure about that I have only used a bufferd j-tag and I have had no problems have you ever used that j-tag on your ird before and have it work?

[Darnat]

A "DCU Peek" error almost always means a bad ground connection or some other problem with the jtag interface

[gordonc]

Darnat is there a way to unlock my 4500 ird I no there is no j-tag port but is there anything I can do I fixed my 2700 and 3100 but don't no how to get my 4500 unlocked I used a volt meter to get my boxx keys from the 4500 but can't figur out how to change the location id from 00000000000001 any idea?

[Darnat]

Try connecting it to the actual chassis and make sure you have the correct placement of the wires to pads!

You could try on a different computer! If you have jtag'ed from it before it should be good. I know my hewlett " pack of crap " can not get the job done. I kept getting an " error reading from ird DCU peek". Good luck.

Gord, you can reset the location ID doing the 'Junkyard fix'.

[gordonc]

cool what is the junkyard fix never heard of it?

[Canuk]

yes... you are actually supposed to use JKEYS with the power to the IRD off (and plugged in of course).. Sometimes I have found that JKEYS gives me errors when the IRD power is ON.

If you had a bad write... you can erase and rewrite again...

Hopefully the image you dumped off the get go was a good one.. Did you do more than one dump and compare the two?


If you have a bad dump you will be looking for a valid TSOP image for your receiver.. I have not had to do this yet so I can't help you here..


Good Luck
