Altera JTAG problem

[GĂłrski Adam]

Hi all,

I need help.
How to send single instruction/command thru JTAG interface with altera
tools. I have to send FACTORY instruction and I know binry code for this
instruction but I don't know how to send it.

Or in other words I have to reenable jtag interface blocked because of
anti tamper feature ( in my design )
Please help.

BR

It ain't gonna happen with Altera-provided tools.

I would look for a general purpose JTAG tool, one with application-
level support. Something like this:<http://www.amontec.com/

I solved my problem with Altera support.

Funny is that when flash contains valid image - jtag is almost disabled
in ep3cls family. Only few commands are working.
